Hey all,,, I'm going to install a 5.7 LS and 4L60E in my 32 Coupe and havae several questions about getting this going. Currently I need info on getting the ECU information on pin outs and the like. There are lots of guy's on CL that will do a harness for a pretty price and being a little bit of a DYI guy I'm really interested in making my own. I've watched several YouTube videos and it doesn't seem to need a PHD to get it done. Was able to get a whole donor car so everything is there to pull that I could need. It ran fine when we fired it up. It was wrecked on the left front and right rear. The axle broke and he went for a ride to the guard rails on the freeway.

I plan on mounting the ECU behind the seat using the interior frame and running the wiring under the carpet (protected) up to the firewall then use cannon plugs to pass through the firewall and attach on the other side for running to the individual components. I'm aware doing it this way will require the wires to be spliced and made longer. I'm not sure if that will affect the way the computer reads signals.

So here come the needs.

Where can I find a wiring schematic for a 2002 Camaro Z28, mainly the ECU and trans harness?

Can anyone point me to online links that show how and what circuit wiring to remove that will not be needed?

Is there a good information source that can be found for doing just this kind of thing?

All input is greatly appreciated,
Back to ya'll.
