another 5.3 in an 85 c10
all right, i finally got the motor/trans shoved into the truck tonight. for mounting i am using ls to smallblock adaptors with the original clamshell truck mounts. i am reusing the th350 mount. i moved the motor mounts up a 1/4" to compensate for the adaptor plates. looks like im gonna have to move the crossmember forward an inch. i checked the driveshaft and still have plenty of engagement. here are some pics....
c10 swap hello jomomma. keep up the good work. you mite be on the road b4 me. my '87 c10(5.3/4l60e) is in the shop be rewired. i had wires everywhere. in '87, c10's came with tbi. im having all that trash removed. please keep the pics of your conversion coming. its very inspiring. also r u upgrading anything? heads/cam. if so give me some ideas. power potential specs. very thanks. decc010974

When I put the LQ4 in my 84 K25 Suburban all I did for motor mounts was build a 3/8" steel plate that extended forward about 2", bolted it to the 4 block bolt holes, set the motor in on the original buckets bolted to original mounts, after setting it in I just marked and trimmed the bucktes around the bolts and then welded the buckets to the steel plate. The 4L80E even bolted up in the same place as the 700R4 did - to easy!
it is almost too easy! well, i just got back in for the night. todays progress includes , reinstalling the fuel tank, running new fuel lines, pump and filter, fitting and welding out the exhaust. tomorrow i plan on tackling the wiring.

Verdad Gallardo i finally got some pics of the work i did this weekend.....
i just finished fitting the headers up. passenger side went on fine. drivers side, i had to clearance the frame rail just a little.
here, i fitted up the fuel filter and an inline walbro 255lph
i just finished getting the intake on.
this is a pic of the power steering connection. i used a couple of metric to -6 an fiitings.
here, i am using a lokar 36" ls1 throttlecable to hook up to the throttlebody.
heres where i am currently. i still got some wiring to do!

Wires removed from 2001 A4 harness for conversion
________________________________________
Okay, checked out my wiring harness conversion and found quite a few wires removed.
2001 LS1 5.7L with 4L60E A4 Transmission
Blue connector....
23 - Low Reference
25 - HO2S Low Signal Bank 2 Sensor 2
28 - HO2S Low Signal Bank 1 Sensor 2
32 - CPP Switch Signal ? what is CPP?
65 - HO2S High Signal Bank 2 Sensor 2
68 - HO2S High Signal Bank 1 Sensor 2
70 - Oil Level Switch Signal
Red Connector....
4 - Air Injection Reaction Solenoid Relay - Coil - Control
13 - Cruise Control Engage Signal
34 - Evaporative Canister Purge Solenoid Control
36 - AIR Pump Relay Control
37 - Cruise Control Inhibit Signal
45 - Evaporative Canister Vent Solenoid Control
46 - MIL Control ? what does MIL stand for?
53 - Ignition Retard Signal
54 - Fuel Level Sensor Signal
64- Fuel Tank Pressure Sensor Signal
2001 LS1 5.7L 4L60E four speed automatic
Removed pins and wires from Blue PCM connector....
23, 25, 28, 32, 65, 68 and 70
Removed pins and wires from Red PCM connector....
4, 7, 13, 34, 36, 37, 45, 53, 54 and 64
Bundle these wires together and route into the cab of vehicle.....
Blue 33 - Purple - TCC Brake Switch Signal - to brake switch - normal 12v positive and Zero
Volts when brake pedal is depressed .
Blue 34 - Orange/Black - Neutral Safety Switch
Blue 46 - Brown/White - Malfunction Indicator Light
Red 17 - Green/White - A/C request switch
Red 30 - Dk Blue - Fuel Enable Control - to VATS if not disabled in the PCM
Red 42 - Tan or Tan/Black - TCC Solenoid Valve Control
Red 50 - Green/White - Vehicle Speed Sensor Signal
Six fuse power block....
12V - Red - always "ON" from battery to three fused outlets
1. 30 amp 12V from fuse to terminal 87 for low fan relay
2. 30 amp 12V from fuse to terminal 87 for high fan relay
3. 10 amp 12V from fuse to PCM Blue 20 and 57
12V - Pink - from ignition "ON" switch to three fused outlets
1. 20 amp 12V from fuse to A/C relay terminal 87
2. 15 amp 12V from fuse to PCM Connector Blue 19
3. 15 amp 12V from fuse to Fuel Pump Relay terminal 87
Bosch Type Relay 1.
Low Speed Fan Relay
Terminal 85 connect to PCM Blue 42 - Dark Green
Terminal 30 Connect to Fan positive
Terminal 86 Connect to constant 12V Power Supply
Terminal 87 Connect to Switched 12V Power Supply
Bosch type Relay 2.
High Speed Fan Relay
Terminal 85 connect to PCM Red 33 - Dark Blue
Terminal 30 Connect to Fan positive
Terminal 86 Connect to constant 12V Power Supply
Terminal 87 Connect to Switched 12V Power Supply
Bosch type Relay 3.
Fuel relay
Terminal 85 connect to PCM Red 9 - Dark Green/White
Terminal 30 Connect to fuel pump 12V input
Terminal 86 Connect to Ground - black/white
Terminal 87 Connect to Switched 12V Power Supply
Bosch type Relay 4.
A/C relay
Terminal 85 connect to PCM Red 43 - Green/White - A/C Clutch Relay Control
Terminal 30 Connect to PCM Red 18 - Dark Green - A/C Compressor Clutch Supply Voltage
Terminal 87 Connect to switched 12V Power Supply
Terminal 86 Connect to PCM Blue 19 - Pink - Ignition 1 Voltage
My only concern is Relay 4. I don't see the logic there. It seems to me that Terminal 86 - Blue 19 - should have 12 Volts at the switch unless it is 12 Volts output from the PCM instead of input into the PCM. GM has always used the pink wire as switched power, red as constant 12V and Purple as the main starter solenoid lead.

let me take a min to explain what that means (i know i wish someone did that for me first.. lol)
when you get a pullout that has the harness on the car, everything is connected except:
3 connectors that were underhood. (named C100,C101,C105)
2 connectors that used to connect under the dash (220,230)
so these 5 connectors are teh ONLY wires we're worred about.
in a nutshell... give ignition power to the pink wires, constant power to the orange ones, take off VATS, and it runs.
the other wires you hook up are just gauge wires, reverse lights, ect.... nothing hard.
its ALMOST a stand alone harness already... only diff is it will have a couple extra wires left after its hooked up.. not a big deal..
theres one more wire not listed there.. its a thick purple wire that goes to the starter.
when it gets +12v, the starter turns the motor over.
also, i bought HPtuners... you will either need HPtuners, or have your PCM flashed to remove the trouble codes and VATS.... if you buy HPtuners, this is NOT hard to do.. i could give you a step by step on doing it easily.... but HPtuners is a little pricy. a tune is a cheaper route, but HPtuners gives you the scanner thats very useful.. along with the ability to change stuff at will... your call on that.

Removed pins and wires from Red PCM connector....
4, 7, 13, 34, 36, 37, 45, 53, 54 and 64
Bundle these wires together and route into the cab of vehicle.....
Blue 33 - Purple - TCC Brake Switch Signal - to brake switch - normal 12v positive and Zero
Volts when brake pedal is depressed .
Blue 34 - Orange/Black - Neutral Safety Switch
Blue 46 - Brown/White - Malfunction Indicator Light
Red 17 - Green/White - A/C request switch
Red 30 - Dk Blue - Fuel Enable Control - to VATS if not disabled in the PCM
Red 42 - Tan or Tan/Black - TCC Solenoid Valve Control
Red 50 - Green/White - Vehicle Speed Sensor Signal
Six fuse power block....
12V - Red - always "ON" from battery to three fused outlets
1. 30 amp 12V from fuse to terminal 87 for low fan relay
2. 30 amp 12V from fuse to terminal 87 for high fan relay
3. 10 amp 12V from fuse to PCM Blue 20 and 57
12V - Pink - from ignition "ON" switch to three fused outlets
1. 20 amp 12V from fuse to A/C relay terminal 87
2. 15 amp 12V from fuse to PCM Connector Blue 19
3. 15 amp 12V from fuse to Fuel Pump Relay terminal 87
Bosch Type Relay 1.
Low Speed Fan Relay
Terminal 85 connect to PCM Blue 42 - Dark Green
Terminal 30 Connect to Fan positive
Terminal 86 Connect to constant 12V Power Supply
Terminal 87 Connect to Switched 12V Power Supply
Bosch type Relay 2.
High Speed Fan Relay
Terminal 85 connect to PCM Red 33 - Dark Blue
Terminal 30 Connect to Fan positive
Terminal 86 Connect to constant 12V Power Supply
Terminal 87 Connect to Switched 12V Power Supply
Bosch type Relay 3.
Fuel relay
Terminal 85 connect to PCM Red 9 - Dark Green/White
Terminal 30 Connect to fuel pump 12V input
Terminal 86 Connect to Ground - black/white
Terminal 87 Connect to Switched 12V Power Supply
Bosch type Relay 4.
A/C relay
Terminal 85 connect to PCM Red 43 - Green/White - A/C Clutch Relay Control
Terminal 30 Connect to PCM Red 18 - Dark Green - A/C Compressor Clutch Supply Voltage
Terminal 87 Connect to switched 12V Power Supply
Terminal 86 Connect to PCM Blue 19 - Pink - Ignition 1 Voltage
My only concern is Relay 4. I don't see the logic there. It seems to me that Terminal 86 - Blue 19 - should have 12 Volts at the switch unless it is 12 Volts output from the PCM instead of input into the PCM. GM has always used the pink wire as switched power, red as constant 12V and Purple as the main starter solenoid lead.

let me take a min to explain what that means (i know i wish someone did that for me first.. lol)
when you get a pullout that has the harness on the car, everything is connected except:
3 connectors that were underhood. (named C100,C101,C105)
2 connectors that used to connect under the dash (220,230)
so these 5 connectors are teh ONLY wires we're worred about.
in a nutshell... give ignition power to the pink wires, constant power to the orange ones, take off VATS, and it runs.
the other wires you hook up are just gauge wires, reverse lights, ect.... nothing hard.
its ALMOST a stand alone harness already... only diff is it will have a couple extra wires left after its hooked up.. not a big deal..
theres one more wire not listed there.. its a thick purple wire that goes to the starter.
when it gets +12v, the starter turns the motor over.
also, i bought HPtuners... you will either need HPtuners, or have your PCM flashed to remove the trouble codes and VATS.... if you buy HPtuners, this is NOT hard to do.. i could give you a step by step on doing it easily.... but HPtuners is a little pricy. a tune is a cheaper route, but HPtuners gives you the scanner thats very useful.. along with the ability to change stuff at will... your call on that.

yup.
all i did was go into the junkyard and grab one off of a GM ODBII car.....

fuel pump jomomma, why didnt you install the walbro in the tank? on my conversion thats what i did. the fuel keeps the pump cooler and you eliminate that winding pump noise. i hated the sound of the holley blue before i converted to the 5.3/4l60e. the only time i hear the pump is when i turn the key to the on position when the fuel system pressurizes.
i just had one sitting in my shop, so i used it. i dont think the inline walbro is very noisy. im sure the in tank version is much quieter though! and genIIIdude, your a freakin life saver. i think i can work with this info! and i have a data port also.
Launching!
