notes: I've had an electrical problem for months (low volts, very slight miss in idle, ALDL cannot connect to ECM) battery, alternator all check fine.
I inspected more of my main harness going to the ECM as well as the wires at the ALDL connector and behind the radio/console; everything looks good. I found out that my ECM is remanufactured. So since everything looks good, I checked with my local auto parts store and I can have it rebuilt for $100. I explained to them how I can't connect through the ALDL and they think it sounds internal. I'm thinking of doing it, what do you guys think?
Also, while looking around I came across this...what is it?
it plugs into here:
