I’m rewiring my car with a new harness as what was left of the old one was more bits of wire nuts, appliance and lamp cord, than harness. I’m installing an authentic cloth-covered reproduction and so far all of the color coding and sizes are dead-on accurate but I’m puzzled over what to do with what appears to be excess length in certain areas. For instance, the branch that goes to the horn relay looks way too long. But it has connectors at the end so I’m inclined to believe it’s supposed to be that way (?). Also, where the wiring for the horns branches off from the headlamps (both sides) looks too long as well. Finally, per my picture below, the wiring that all goes to the dash seems to be about 30" in length. Is that correct or am I supposed to trim all to a shorter length? Was it meant to be that long so as to make dash removal easier? The car wasn’t left with enough of the original wiring to use as a reference.
To those who’ve been down this road before, I’d appreciate your input. Thanks.
