Lightbulb 94 thru 97 PCM pinouts w/symptoms and codes

I scanned the 8 pages in the shop manual that has the PCM pinouts and wrote in by hand the differences from the 94 & 95 OBDI pinouts. Or should I say, lack there of.

I've had this manual for 3 years and it escapes me why I never thought to do this before. I'm good but I'm slow

Here's an example of what the 8 pics look like and the information they give you.


I didn't want to use too much band width and show all eight but here's a list of the 8 views. (each connector is split into 2 views)

black1-2

black2-2

blue1-2

blue2-2

red1-2

red2-2

white1-2

white2-2

Notice it gives you the codes associated with each signal AND the symptom each signal would give if it were lost. I think it's great.

I hope it helps someone in the future. Maybe Rob will add it to his website.

Happy Holidays
Dave
