Dave,
Today, I followed your suggestion to flag each wire on the 4288 ECM harness with old and new locations in black and red or blue ink, respectively. Interestingly, I found some variances between the listing and my ECM harness. In a few instances, there were no wires in the locations due to the function(s) not being available on my S10, i.e., Charcoal Canister Purge Solenoid (A3), A.I.R. Converter/Port Solenoids (C1 and C2), Power Steering Pressure Switch (C8), MAT (don't know what this device is) Signal (C12), and Injector "2" Control (C15/D14)...OK no problem! In 1 or 2 instances, there were wires of different color and guage.
In general, what do I do with pins and wires which I do NOT need? Do I just move them to the side and tape the pins and bundle them?
With regard to the Swap Notes:
1* I have a 700r4 but no TCC light so what do I do with this wire?
2* Have no clue what I should do.
3* My 4.3L does have a single wire Knock Sensor. Do I re-pin this B7 (red)?
4* No wire and no A.I.R.
5* My S10 is a automatic 4x4 and there is a high/low gear switch. What do I do?
6* No problem...no wire.
7* What is meant by "store in small connector?"
8* No problem...no wire.
When I re-pin the harness and install/connect the PCM 8625, what happens to the ALDL...will it still function? How do I get codes and will the Check Engine Light still work? And lastly, just out of curiosity, what kind of on-board diagnostics (OBD) will I have?
Thanks.
I double checked the flag notations and will make another pass tomorrow. After that, I will prepare an exact listing and post it.
