I have most of the drivers side harness hooked up to the 350 after swapping from 305 cfi to 350 carb but there are a few loose ends that i am not sure what they go to. the red single wire is on the drivers side on the firewall behind the wheel well. the other single wire is on the passenger side and comes out of the harness. thanks for any help.

first one not sure
second one no picture is showing
third one is to your a/c compressor clutch

 

thank you for helping me cross that one off the list.

Red one by the C100 is the fuel pump test connector to the relay.

2nd one I think may have been the timing disconnect for adjusting base timing.

Could also be an O2 sensor plug, need a shot from further away to know where its actually located.

 

I dont think it went to the o2 sensor but i will double check it tomorrow against the o2 sensor. Everything i read on this swap said that the ecm harness (passenger side) was no longer needed but from what you said and my own examining the sensor it seems like the fuel pump and oil pressure gauge were in that harness. Am i better off hooking the ecm and harness back up to have the fuel pump relay and oil pressure sending unit connection or is there a more common fix to this? I cant seem to find too much info specific to swapping a crossfire motor, mostly just unanswered questions or answers beyond my ability to understand. Thanks for the help.
