I really need help identifyng the extra wiring in an 91 Z harness. I've gone thru the harness an labelled all the connections I have prints but here are still some left. At that critical point, also what did you use to remove the terminals from the 15 pin and fuse block connectors? Thanks D

 

To remove the pins from the firewall connector remove the outer plastic piece that has the locking tabs then remove alot of that nasty grease. Now you should be able to see on one side is a little white strip, just start pulling a little at one end then move to the middle then move to the other end.when you get that out you can then release the retaining tabs for the pins and pull them out. to get to the release you go in from the pin side of the connector.

for the 15 pin if you are referring to the one near the ECM just release the two tabs on either side to let the pins slide out the back after you release them from the front side.
Hopfully this helps and makes sense to you

 

Thanks for the help, I have all the bulkhead pins out, starting on the 15 pin connector. D

 

What connectors are you trying to identifty?

 

I have all the connectors i.d'd per the ecm schematics, there is still 4 connectors unidentified. Also, I do not see an connector for the alternator, need to id starter circuit if installed. Not familiar enough with F-bodies to determine. D

 

Starter wire is a large gauge purple wire in the driver's side wire bundle coming out of the bulkhead connector. There's also two or three large red or orange wires that connect to the main post of the starter along with the positive battery cable.

You still didn't describe your 4 unidentified connectors.

 

I have all but 2 connectors identified, they are: 1) single white connector; tan/white wire coming from bulkhead fuse connector 2) 4 pin connector, 2 wires, large red wire leading to starter terminal, small brown wire goes to splice, with wires going to both fan relays then the bukhead fuse connector. Thanks for the help D
