Finally got all the wiring on the front end of the Stang done today.

Stared the headlight harness and alternator harness at about 10 p.m. last night when the boys went to bed. I had already installed new park lights the other evening and had put on a new high and low pitch horn the other day. When I bought the car it had one cheap / plastic aftermarket horn on it that didn't work. Wires for the other horn were no where to be found.

Worked till about 1:30 a.m. then realized that my 5/16 deep socket had walked off. So a fast trip to the store today to purchase a new socket and it is done. Hate being 3 bolts away from having a job done then having to leave it for the rest of the night.

At any rate, I started it up and let it run for a while to make sure I had the alternator hooked up right. My guess is that if it was running and not charging the battery it would have died after a few minutes. Let her idle for about 15 minutes in the drive way. I had to read the wire diagram closely because they had some half baked hack job on my alternator....got rid of all that splicing and restored to correct connections with correct color codes on the wires. Everything (except the horns) appears to work on the front. I tested the lights on both high and low beam, the turn signals, etc.

The biggest problem I had was the part of the harness that runs through the tunnel under the radiator to come out over by the alternator. What I finally did was straightened the wire handle on an old fly swatter. Basically, that gave me a long coat hanger that had been straightened. Put that through first, electric taped the wires to the coat hanger and pulled it through. Still had a heck of a time getting the wires out of the small hole on the other side but finally got it worked out.

Done with that piece so after I figure out my floor pan issue I hope to move on to replacing the wire harnesses on the rest of the car. 42 year old wires = not good. Have to admit I am tempted to pay someone to do the under dash harness since that one looks a bit more complicated. However, I took some good advice from someone and purchased the shop manual for the electrical system on a 1966 Mustang.

Only have one question left. I purchased the new park lights, retaining deal, lens, etc, etc. The complaint I have is that the rubber plug on the parklight wires is smaller then the hole it is supposed to plug on the car.

Is there any sort of glue or something of that nature that I can buy to "stick" the rubber plug in place? I was thinking maybe some of the adhesive they sell to put on the chrome trim pieces.

Any ideas?

 

nice going :-) can you make a picture of it? don't really know what you mean here

 

Thanks Kalli.

A tip for anyone planning this any time soon. I would have left the old wire harness in the tunnel that goes under the radiator. If I had it to do over again, I would have cut it on each side then attached the new wires to it to pull them through there. Live and learn but it would have prevented a fly swatter having to give its life for the Stang...LOL!

The deal I am talking about is circled in this picture.



Basically, you mount the park light body then the wires go up through the fender to plug in to the headlight harness. The rubber plug is supposed to seal the hole. However, on mine the hole is much larger than the rubber plug.

I was hoping to find something that would make it stay but at the same time not be so stuck that it would be super difficult to remove if I ever had to take it out of whatever reason....for example I will need a paint job sooner or later.
