Wiring Job/Write up on my '72 Camaro with '06 LS2 engine Dear all,
Two weeks ago I started modifying my stock engine wiring harness.
I started this job by asking some help on this forum in identifying some connectors https://ls1tech.com/forums/conversio...onncetors.html
Now I have some new questions and I am starting this write up to help others as well.
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
Since my car is a '72 camaro I don't have to worry about any 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. Later on more about that, now some wiring...
First Step:
I plugged in all connectors on the engine and routed the harness to the spot I wanted to enter the car. Which is right below the rear passanger side head, in the transmission tunnel.
Second Step:
I took some hours of unwrapping all the wires by removing all tubbing and tape. Sticky job, but very revealing and helpfull understanding all the wire routing.
Third Step:
I removed the engine from the car and put a table behind it, so I could work a bit easier on the harness.
Fourth Step
After some good adivise on this forum and with the kind help of member CalEditor - A.J. who send me this Word file http://kandycamaro.louispeperzak.nl/...6_LS2_Vett.doc
and I used these files on LS2.com http://www.ls2.com/boggs/c6/Fuseblockc1c2c3.htm
and http://www.ls2.com/forums/showthread...hreadid=405808
With those documents printed, I started identifying the conncectors and wires.
Fifth Step:
I began labeling and referencing all wire I knew. What a hell of a job... pfff
very time consuming and confusing. I learned a lot of new termology, like TFT is not a screen, but Transmission Fuild Temperature.
Every label is refering to the connector and pin it is from and it's function.
Then I started cutting some wires and connectors off, which I am positive I won't need, I think...
Sixth Step
I setup an Exel sheet and put in all wires I knew.
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
(I will also put down this file in writing in this thread also, later on this week)
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 to 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 and assigned some, but I need more info. I will post a list on what I will remove on wires and what I will have be removed on programming.
And I started unwraping my 4L60e harness, but I haven't found any connector/ pin file on that one...
I will update this thread as soon as I get a step further, till then I can use all the help I can get.
Thanks Guys!
Peter

hee my57120&56gmc, I wish it was that easy... you also need all the underhood fuseboxes and probablly you need the BCM harness aswell...
AJ has helped me out a lot, but I haven't been able to do everything jet.
I am really busy right now at work and i am doing some house rebuidling at my girlfriends mother... so unfortunadly I don't have any time to work on the car.
as soon as I have an car update, i'll let you guys know.
