Hello gents,
I'm chasing wires and the wire loom coming into the engine bay from the driver side fender has some "unclaimed" wires sos to speak. I was hoping someome could point out what wires go where. Also can someone explain what the "pp1" and "f1" connections mean next to the taillight relay on the fuse block on the driver's kick panel mean? I don't know where things are located so I find it difficult to follow and troubleshoot problems. This is for a base model 91, 22RE RWD pickup. Thanks all.

Show the markings..

Show your unknown wires..

Describe exactly what it is you are trying to accomplish.

 

The wires I'm having issues with are the white "esv" labeled wires where they come in through the fender and sit under the air box. I'm trying to piece together a harness from a 94 into a 91 due to the fact that the older harness was all hodgepodged together. Originally I had a code 13, which the wiring could have explained. Now it just cranks and won't start, likely cause my wires arent matching up correctly. I'm sure I'm not making much sense, but i can't describe what I'm talking about cause I'm not even sure what circuit they are part of. I just want to get the truck trunning as it's my daily driver.

Sorry, some of us have trouble seeing words. See signature.

 

What your doing is best done with having a copy of the Electrical Wiring Diagrams for both years the wiring harnesses came out of .

Different years can use different colored wires and connectors making things so very frustrating

If your trying to splice bits and parts even more places for poor connections

If you can`t explain what your looking at How could we have any idea

 

Pp1 and f1 are probably casting marks and not relevant, I don't recognize those as any signal wires...

Autozone provides wiring diagrams for free registration required, but they are also findable on Google.

 

I eventually figured out what I needed to know the name of (junction block #1), thank you all for the help. I understand I didn't give a lot to go on, but until I learn what is what, I'm at a disadvantage for asking for help. I'll try and be more specific for descriptions in the future if I don't know the name of something.
