Jeff,
Thanks for the reply. I didn't realize junk yard computers were so cheap. I only looked at new ones. Looking on car-part.com I see yards selling them for $20. Will it have to be reprogrammed for my car?
How do you ohm a wire between the PCM and BCM? The leads on my meter aren't nearly long enough. Do you just use a jumper wire?
Do I have to ohm the wires or can I test them by checking for voltage on any of them?
