Speedway New 12 Circuit Wiring Harness?

This is for "general" electrical discussions. Audio, security, remote start, and power accessories should go here, since they don't seem to fit anywhere else. Not for diesel-specific (like glow systems), or gasoline-specific (like ignition systems) topics.

Speedway New 12 Circuit Wiring Harness?

Postby zster » Mon Feb 26, 2018 6:54 pm

Hey y'all,

Been a while since I've been here. Had other projects on the top of the list. I'm in the process of deciding if I should give up on my LUV or keep fighting for her.
She's been having serious electrical gremlins and electrical is so NOT my forte or my interest.
It's a 1980 chevy luv 4x4 that I did a diesel swap into. kept the original wiring harness and now everything is going haywire.

my buddy pointed me to this:

Anyone had any luck with these?

thanks for the input.

I'm trying to clean up my wiring from a previous owner of my 81 Diesel LUV. I'm getting to the point of just getting something new to put into it. Have you gone with the speedway harness? Did it work for you, any issues?
