Guys I just started unwraping my stock LS2 manual corvette harness and I really need some help...
I will be converting this harness to work with auto trans aswell, any help/advise?

Can some one help me identify these connectors??? (they seem to be going in front of the motor)




And please identify these... these three where half way on the main string close to the computer plugs. 1 anf 2 fit together, but I can't imagine it blongs that way...?




Thanks

This is all ABS/TC stuff

1. EBCM -- ABS/TC Module
2. Battery Supply Positive Voltage Connector
3. WT & Brn = Variable Effort Steering Solenoid
4. D-Gn & Tan = Wheel Speed Sensor Right Front
5. L-Blu & Yel = Wheel Speed Sensor Left Front
6. Brake Fluid Pressure Sensor

I don't think you need them

I can get you the information on these connectors. contact me at caleditor@airfueltuning.com

1. C184 - Transmission Harness to Engine Harness
2. C180 - Instrument Panel Harness to Engine Harness
3. C186 - Engine Harness to Forward Harness

You wouldnt need any of the first harness.
Some of the wires on 1,2,3 you will need that will pass through firewall eg starter relay sig, GM LAN, APP wires, etc.
I would remove these from the connectors and figure out a different way to get them where they need to go.
A multipin bulkhead passthrough connector maybe a good choice

pjtimmer

Thanks alot for your help guys!

I went straight to the garage and cut the ABS/TC connectors out, offcourse I labeled the wires first. I thought they had something to do with the fans wiring....?
And only two twisted wires went to the main PCM/ECU, they came form connector one in the first picture, what are they for?


Next questions:
I could also need some help with identifying the wires in the fuse box and advice what to do with them.



Can I use this C2 diagram: http://www.ls2.com/boggs/c6/Fuseblockc1c2c3.htm

or does my year has another diagram?????? I have a '06 manual corvette harness.



Another question, I can't seem to find any connector that fits my pedal assembly? did that came from another harness? where can I find the right connector? and which wires to use?



Thanks again guys.

I will work up a new word doc today with the schematics and some more pinouts.

pjtimmer

Thanks a lot, you have been a great help!
I almost labeld everything last night with your lists.

Now I have even more questions, like: what is low reference and 5 voltage reference? and what to do with it...


I will post a concrete list of questions later this week and I will start a write up on how I did everything with pictures and such.

Did every thing work out?

pjtimmer

Thanks for asking!

Your help on those connectors was great, I think I found every wire description, but...
Could still really need your HELP, but I wouldn't dare to ask again.

I need to find out what to do with all those identified wires...


Here are my Specs:
- '06 Corvette LS2 with stock 'manual' wiring harness + E38 PCM
- '05 Corvette 4L60e with stock harness + TCU (and GTO belhousing & tail)
- BRP engine mounts and transmission crossmember
- BRP Longtube headers and
- Cadilac CTS oil pan
- Autometer gauges (oil press, oil temp, water temp, trans temp, fuel press, volt, fuel level, tach, speedo)

Since my car is a '72 camaro I don't have to worry about any (european) modern emission regulation, so no EVAP and no rear O2 sensors.
I also removed the AC. I did add some sensors for my autometer gauges.

Questions:
- What to do with all those identified wires?
Please find all wires in my Exel sheet The file is organised in Description, Wire Color, Connected to, Pin, What to do with it? Xls Version-001 http://kandycamaro.louispeperzak.nl/...ions_V-001.xls





Now I know many of the wires, but I still don't know what to do with it...
- And I have a lot of new questions; like what is Low Reference? and what is it used for and why I have so many?

- Or what is 5-volt reference is used for? what to do with those?

- Or I only found one Fan wire, I have two cooling fans, how to get two speeds out of the compter and what wires to use?

- I have pink wires comming from the engine side, which all need some ignition power and should e fused, but what to do with the pink wires from the PCM? hook them to the ignition wire also?

I removed some wires and assigned some, but I need more info. As sson as I have the answers I will post a list on what I removed on wires and what I will have removed on programming en how I did all this, so everyone has this info.


Thanks

I was helping a few projects and I guess I forgot to send Schematics. No problem I will get them out to you.

pjtimmer

Thanks for your help again!

Now I realize I really have to learn how to read those schematics...

I will put up a list as soon as I understand them myself

Peter

CalEditor

Use the Schematics and the Connector Pin-Out I sent you and you should be able to understand them much easier.

The 5V and Low Ref Busses will go to a lot of the sensors.

pdsq98gt

The 3 wire sensors have to have a power wire (5v ref), a ground wire (low ref), and signal wire (the output voltage to the pcm)

pjtimmer

Thanks guys,

All the engine sensors are in the engine and hooked to the harness. I need to find out what to do with all wires that are left.

I've put them in my exel sheet:
http://kandycamaro.louispeperzak.nl/...ions_V-001.xls

Here is a print screen of the document:


I got a lot of wiring schematics from 'CalEditor' so I will try and figure out what to to with my questions above, but if anyone knows allready, I really could use the help.

Thanks

Peter

pjtimmer

Well, I have tried to figure out how to read those wiring schematics... unfortunadly I don't understand what to do with my questions in the above picture.

If you guys can help me again? answering the questions in white in the picture above, that would be great.

thanks, I will be awaiting your responce

The Fuel Level Sensor MUST be hooked up to the PCM.

If you don't do this it will hurt performance

pjtimmer

Good to know, I use a custom fuel tank with a 0 to 90 Ohm fuel level sender for use with my autometer gauge (two wire)

should I hook those wires to the two PCM wires? Does it matter which goes to which wire?

How about my other questions?
Caleditor, I wouldn't mind paying you a symbolic $ amount for all your help. Certainly not if you can guide me true this proces until my first start!

thanks

The server is down I will get this out to you soon

pjtimmer

Thanks man! Let me know if I can get or sent you something!

I need to know the Terminal of the PCM for the one you have listed as Fuse box C2 E5

pjtimmer

Thanks AJ!!!!!!!!

Now I am a few steps closer to a working harness...

The terminal of the PCM for the one I have listed as fuse box C2 E5, is: C1#59 I got the description wrong, it should be Ignition 1 Relay control... sorry.

BTW I don't use AC.

You mentioned I DO need evap canister control... but why? I will add a CharcoaldumCanister next to the fuel tank. Can't I just delete EVAP?

Thanks alot!

Peter
