Make sure to be very careful in older cars when you wire tuck. esspeically if you are just moving a few stock wires/harnesses. I had the worst luck and ended up breaking my main alternator wire. Damn thing sent me on a wild goose chase. Alternators do crazy **** when they aren't charging anything.

 

how did u manage to have an alternator problem? u really dont have to extend any wires on the motor harness.

 

Yep, no need to extend but when u pull the harness into the cabin don't think those old wires are as flexible as the used to be.

 

when i rewired my engine harness, i cut wires at the sensor and used new wire. i ran all my under hood wires through a single loom through my firewall. all other under hood wires the frame horn exiting behind the headlights.
