TOPIC: what does the fuel injector and ignition harness connect to?

what does the fuel injector and ignition harness connect to? 03 Jan 2014 12:52 #16518

I honestly am not the best at reading electrical diagrams. I am considering replacing both the fuel injector harness as well as the ignition harness on a '89 along with all the sensors. Is their a list anywhere that brakes down what each harness connects to?thanks

the FI harness wraps back into the fuse panel and the electronics be the fuse panel. The ignition (or if i read you right the main harness that connects around the motor to the 10 pin connector) wraps from under the motor though it to the 10 pin (and fans). If you mean the other main harness in the car under the dash... that bitch connects to everything and I do not recommend replacing that unless you have the desire to take most the car apart... I have never seen a harness go so many places without breaks/connectors.

I just pulled a full set of harnesses out of my 89 parts car. What are you looking for... I will make you a deal on them depending on what ya need. emerald (att) adair (dott) net

I would suggest that you need to be really, really certain that you need to replace the harnesses. This is not a trivial task - it can be expensive in time, money and effort.

A very specific, detailed description of your problems might be a good idea first. It is very possible that the problems can be solved more easily.

Can you better describe where this "10-pin connector" is located? Is it the connector on the US passenger side, next to fender wall and part of the hot start post, that most people refer to as the "14-pin"? Under the plastic cover at #15?
