1G Cut wire harness

[Thungar]

I have a 91 gsx i just got a wire harness for free from a friend from a 1991 gst and its ecu. but its missing some connectors. i need help identifying the missing connectors. Sorry for the pics they really don't show enough but maybe someone is a genius with these.

What is this yellow butt connector?

No idea on the yellow the three are AC coolant temp and ecu coolant temp sensor if I'm not mistaken.

I would lay out the harness on the engine bay, and see what meets up and whats missing. Once you have everything mapped out it will be easier to figure out what is missing. Then, the number / color code of the wires should be able to help narrow down what all you need.

For the first one, check C-56.

For the second three, check B-29 through B-31.

For the third, check A-13.

I think on the last one is A12 break fluid level sensor. c56 is o2 sensor check. do i need to hook any of this back up some how? Are any of these missing connectors worth replacing?

Oh, that one. Yeah, probably.

C-56 is normally an open connector. Of the other three, the one that is important is B-30 for ECU control.
