Alright, having FUN wiring up my 96 LT1 with LS1 Conversion, needing to see if I could get something similar to the following link on shoebox's site but for the LS1, he has everything listed for the LS1. The pic shows some of the connectors in question. Not sure if the numbers are the same for the connectors on LS1 as LT1 ex. c100 etc. If someone could please provide this I would really appreciate it and would make my wiring life a bit more easy. 98 LS1 connectors (c100, c105, c210, c220, c230) Thanks

anyone know if this is correct info for a 98 or what year this is?

OEM LS1 Harness ID & Connectors...

The LS1 harness basically connects to the rest of the car thru a few specific connectors. The first four are located in the area of right shock tower...
...C100...black 10 pin connector.
............A- pink (bank 1 ign/inj switched 12v 15amp power in)
............G- pink (transmission/EVAP switched 12v 15amp power in)
............J- dk green (cooling fan 1 relay control out)
...C101...grey 10 pin connector.
............B- pink (bank 2 ign/inj switched 12v 15amp power in)
............D- dk green w/ white stripe (fuel pump relay control out)
............E- pink w/ black stripe (switched 12v 15amp power for PCM in)
............G- orange (constant power for PCM 12v 50amp power in)
............H- black w/ white stripe (ground in)
...C102...
............A- purple (starter solenoid "start" power in)
...C105...black 8 pin connector.
............B- pink (trans/stop lamp/heated o2/MAF 12v 20amp power in)
............G- white (tach signal out)

The other two are located behind the firewall, inside the passenger compartment, on the other side of the firewall grommet.
...C220...natural color 10 pin connector.
............E- black w/ white stripe (ground in)
............G- brown (to back-up lite switch 12v"+" power input)
............H- lt green (from back-up lite switch out to lites)
............K- dk green w/ white stripe (VSS signal 4000ppm speedo output from LS1 PCM)
...C230...blue 10 pin connector.
............B- brown w/ white stripe (MIL lamp)
............E- dark blue (VATS fuel enable input)
............K- dk green (serial data class 2 output from LS1 PCM to OBD-II connector)

The only other two points that the LS1 harness needs connected are down by the LS1's starter...
...purple wire... needs to be connected to the starter solenoid's "S" terminal.
...open ground lug... needs to be connected to a block ground.

The GM color code for wiring is very consistant. When in doubt, the following applies to any loose ends you might end up with in connectors C100, C101, C105, C220, and C230...
...red wires...all loose red wires should be connected to "12v+" protected by a fusible link.
...orange wires...all loose orange wires should be connected to "12v+" protected by a fuse of at least 10a.
...pink wires...all these wires in the LS1 harness should connect to a 12v "switched +" power source hot in "start" and "run".
...black...all these wires in the LS1 harness should connect to chassis ground.
...black w/ white stripe...all these wires in the LS1 harness should connect to engine ground.

I'm working on a 1998 F-body harness now for my BMW swap. I have a damaged 1998 harness I am trying to sort out. I have the GM Service manual, and have done some screen caps (some of the info was cut off on the right side, I think it is still OK though) of the several connectors listed. My harness has C100, C101, and C105 connected, the others were cut off. I'm guessing at the missing ones. I hope this helps you:
C100:


C101:


C105:


C210:


C220:


C230:


I have deciphered the power feeds as well. The above is not really any help to tell you what the pink or orange wire does:
C100-
A, Pink, 15 amp switched, powers bank 1 injectors & ignition
G, Pink, 15 amp switched, powers Evap/EGR

C101-
B, Pink, 15 amp switched, powers bank 2 injectors & ignition
E, Pink, 15 amp switched, PCM ignition feed
G, Orange, 10 amp constant, PCM battery feed
H, Ground

C105-
B, Pink, 20 amp switched, Sensor power- O2, MAF, etc. & trans rev. inhibit, skip shift

I will update as I go through the manual.

Yes worse (meaning more re-pinning involved) there is a website that AutoZone sponsers or owns (as much as I HATE Autozone) that you can pay like $20 and get access all pinout info for your year model and the engine year model as well....I only used it a couple of times trying to run down a wiring problem I was having during my swap. I forgot the website off the top of my head...I'll try to dig around for it when I get a little more time.

It's a shame someone couldn't post pics of the needed connectors/pinouts so he could save the $20 .

In a nutshell, here is the generic 1998 info to wire the harness into a vehicle (auto trans stuff, fuel tank, AIR and EGR wiring are not included here, refer to above pinouts to add as needed) :

C100 Black color
A: Pink-15 amp fuse, bank 1 injectors & ignition
B: Green/White- AC compressor relay
C: Dark Green- goes to compressor + wire (PCM can tell when AC clutch is engaged)
G: Pink- 15 amp fuse, evap/EGR
H: Dark Blue- Cooling fan #2/3 relay
J: Dark Green- Cooling fan #1 relay

C101 Gray color
B: Pink- 15 amp fuse, bank 2 injectors & ignition
D: Green/White- fuel pump relay + signal
E: Pink- 15 amp fuse, PCM ignition + feed
G: Orange- 10 amp fuse, PCM battery + feed
H: Black/White- Ground

C105 Black color
B: Pink- 20 amp fuse, sensor power

C210 "Neutral" color
B: White, cannister vent solenoid

C220 "NAT" color (natural?)
A: Red- alternator to dash lamp + side, must have idiot light or resistor in this line for alt to work properly
B: Tan- Oil pressure feed for gauge
C: Brown/White- Low oil lamp + feed
G: Green/White- speedometer output
K: Dark green- Coolant temp feed for gauge

C230 Blue color
B: Brown/White- SES lamp + feed
D: White- Tachometer feed to dash
E: Dark blue- Fuel enable feed (VATS)
F: Dark Green/White- AC request
K: Purple- Signal to datalink/ALDL connector under dash

is the pcm power wire the wire that has a single connector with orange seal on the pass side coming out of PCM wiring? I think its S106??? Anyone?

circle connector by oil cap in pic above.

Please take the time to review the pinout pics I provided above, as well as the simplified data in my second post. The answers to everything you have asked are there, and I have included the proper size fuses called for in the service manual.

The PCM gets switched (i.e. key on) power from a pink wire at connector C101-E and constant (i.e. battery) power from an orange wire at C101-G. The only single connector in the area of the PCM should have a large purple wire attached to it that goes to the starter. This is connector C102. I did not see enough of the connector by the oil cap in the pic you provided to know which one it is, but from what I can see (purple wire?) it looks like the starter wire.

Service manuals for your '96 as well as the '98 would be of great assistance when doing something like this.

EDIT
I just realized this was posted in the wrong forum. You should check in the conversion/hybrid section, there is a FAQ that also answers these questions. Here is a link to a good thread with another link to a 1998 overall diagram (see post #5) :

i have all the diagrams and pinouts, ive looked over everything, and it doesnt say that the pcm power is in connector 101. Says fuse output connection ignition and batt but didint say if it was PCM or what so I didnt really know. All I know is pcm got its batt power from 20 on one of its connectors and it said S106. I will go by wat your saying.

So as far as all of them that say fuse output, could you tell me exactly what they run, I see yall have most listed but like on 230 i dont know what it is and on 105. thanks for the help.

The GM service manual in the pinout table does not come out & say this wire provides power for this function... that would be too easy. The above info was found in the diagram sections of the service manual. It is like learning to speak a new language. I have not looked into the naming of these parts, but from reading the manual "S" listings like S106 appear to be where wires are joined (soldered?) together, and "C" listings are where there is a connector. If this is the case, S106 would not be a connector, it should be two or more wires joined together.

All the power functions come from the 100-101-105 connectors. The 210-220-230 are the ones that went inside the car and provide info to the dash, gas tank info, etc.

I think you will find many of the wires from your '96 will crossover for function for the '98 harness. This should be a lot easier than say a Toyota, Mazda, or BMW harness since the same company made both. You need to compare the pinouts from the '96 C100-101-105 connectors (these are probably on Shoebox's website, don't recall if he had the OBD2 96-97 cars there) to the '98 ones I provided above.

Worst case, you can probably find someone here that has a '98 LSx in a 96-97 F-body & see what they did.

after finding more info, this is what ive come up with, that wire im talking about is the starter wire, im guessing i wire that up into the dash where teh LT1 starter wire is.

Mike96z

iTrader: (78)

a few questions.

C100
D. Reference voltage feed 5 volt (where would i get this 5v reference?)

E. LT1 is Air Pump, LS1 is TPS, (so how would I go about wiring this up? Find where LT1 TPS is wired to?)

K. Is sensor return, guessing that was for TPS, so does E go to TPS and K comes back from it?

C101
K. Where would I get the ignition retard signal from?

C220
C. LT1 says Oil level feed to cluster, LS1 is low oil level indicator lamp, i think these are the same, just worded dif, anyone confirm?

E. LT1 is PCM ignition fuse, so I think i would take the pin out of C101 and wire it into the dash where the power for pcm is coming from?

J. What should I do with that? What exactly is it for?

C230
G. They are diff on LT1 and LS1, could they actually be same? LT1 is power feed from sensor fuse #10, LS1 is fuse ignition 3.

C210

How would I wire this all up for the LT1 fuel pump.

C105
A. I put diff because LT1 is TCS spark retard, LS1 is TC Indicator failure, are these the same?

B. Different, but they are both from fuses it seems, could be the same, worded diff.

C. LT1 is TCS Position, LS1 is TCS switch signal, what to do as far as this.

G. for LT1 is TC active, LS1 is tach signal.

So im thinking the TCS for LT1 could be wired to E on C100 for the LS1 and the TC Active is the same as LS1 TCS switch Signal?

the rest are the same and wire up, anyone know where to buy the tools to help with pinning and repinning the connectors? Thanks

I have attached a MS Word 2003 document with all the info I could find based on the service manuals and other sources. There will be a lot of work if you want to hook everything up such as fuel tank info, AIR, etc. You can probably do without this, but will need HP Tuners or LS1 Edit or someone to cut out the SES codes. The main things are the power and ground for the PCM as well as the fan controls. All of these are covered.

As was stated in another thread, the body harness is different, and I have no way of knowing if the gauges use the same data or if the datalink connector is wired the same.

Mike96z

iTrader: (78)

Datalink connector is wired up the same way, not using AIR, EGR, A/C and the fuel gauge will read but wiring the fuel pump is a question. I found grounds and power to PCM and the fans hookup the same as the LT1 so no probs there. The body harnesses are different but most of the connections are the same as you can see on my diagram. The ones that arent the same are in question.

How many wires are suppose to go into the PCM from connector C105? I only have two going into the connector and there is four on the other side of the connector. The Pink one was till in tack, but he tan/white one was out, but these are the only two I saw there, is ther suppuse to be a third or even a fourth? It is a 1998.
