help id these connectors?
pic 1 - 16 wires from the same bundle as the pcm connectors (connector missing)? Both Blue and red wires are accounted for. Edit-Got it, this goes to the TAC module, I had to buy a new connector from GM

pic 2 - two connectors A-B (passenger side fuel tank)? Edit I found 'A' it goes to the harness on top of the tranny. 'B' has the same pins as the tank but both connectors are female. Unless something goes between them?

pic 3 - four connectors A-B-C-D (passenger side front of car and one green plug in the background)? Edit-these go to the dash harness...

pic 4 - 3 connectors A-B-C (Near PCM) ? Edit-these go to the dash harness...

Pic 5 - 5 connectors A-B-C-D-E (Near PCM) ?
Edit-these go to the dash harness...

In this pic you are missing the red connector that goes to your PCM. For information on wiring this connector, you can send eurospec1 a PM. He changed his 97-98 PCM over to a 99-00 and will have some good info to share.
For the rest of the pics, Bill Curlee is probably the man to contact. I'll PM both of them and make them aware of your thread. Both of them are extremely helpful guys. Good luck.
You wouldn't happen to be building a GTM would you?

Hmm this is quite the interesting question!
First i have to ask what year is that harness?
Second that blue PCM connector is broken, your gonna need to replace that.
For those 16 wires in your hand near the PCM connectors your probably gonna have to get a pcm pinout of the exact year of your harness, and go through the PCM connectors 1 wire at a time and figure out which ones are missing, from there you can probably go by wire color and figure out where those go, those are pins that go into your PCM.
let me know what year that harness is and ill try to help ya out.
