1972 Wiring Harness Questions

[Glen C.]

I started today to try to sort out some electrical gremlins and found some strange "bubba" work had been done on my front wiring harness. Two extra horns had been mounted and wired, the harness was not secured once it turned at the front fender and was laying across the bottom radiator mount. There was a lot of patches using electrical tape. I think the best fix is to get a new forward harness and clean it up rather than trying to repair this one. I did have a few questions that I was hoping someone could help me with:

1. Who maked the most correct wiring harnesses?

2. My clips are in place along the driver's fender but once the turn is make across the nose of the car they are missing. I know from the aim there is a clip next to the horn that has a bolt through it. The other holes do not seem to be threaded and I see some plasic barb retainers taped into the existing harness - are these retainers correct for the non tapped holes? What is a good source for whatever clips or retainers that I need.

3. The installation under the hood looks fairly straightforward but the AIM shows one section going through the firewall with a grommet. Withoug a lift how difficult is acess to this penetration going to be.

4. I'm planning to send the correct horn off to be restored and would like to go ahead and send the alarm horn as well. On the alarm horn are ther any tips to accessing the mounting bolt?

5. Is there anything else I should change out or check while I'm doing this work that I'm not thinking of?


Sorry for all the questions but I want to get this right.

Thanks for any advice,

Glen

Hi Glen,
Happy New Year!
I'll try a couple.
#1 Lectric Limited is a good source for a new forward lighting harness.
#2 I believe there are 4 of those barbed fasteners taped into the harness and they hold the harness in place once it's through the core support and past the last J shaped clip that's mounted on the forward side of the left hand apron. No other clips are used along the headlight header. There are also smaller clips lower down on that apron and the passenger's apron that are used to contain the wire leads to the side marker lights and parking/signal lights.
#3 I believe the only part of the forward lighting harness that comes through the firewall is the bundle of fiber-optics cables... does your car have fiber optics?
#4 ?
#5 ?
Good Luck!
Regards,
Alan

Hi Alan,

Happy New Year to you also. Thanks for the info. I'll look at aim again as I don't have fiber optics. I need to look for the lower clips as I don't remember seeing them. I'll check with Lectric Limited on the harness.

Thanks and have a great week.
