I'm looking for a wiring diagram for the ECU on my 2003 Cav, I'm hooking up my GReddy E-manage. If anyone out here has any info or can get them for me that would be awsome. Plus I'm wondering where the ECU is located.

I went to Mews in Ottawa Canada, and they gave me diagrams for the PCM (Powertrain Control module)??according to them my car doesn't have an ECU, just a PCM. I find that hard to belive......

Thanks Guys

Check out this website, I believe it still has a walkthrough in the library for the Ecotec emange setup. http://www.ny-jbodies.org Good luck!

The ECU is located next to the passenger side strut tower just above the header a square looking thing with two connectors on it

ECU and PCM are the same thing, just an acronymn used interchangably.
