Oh my gosh, I'm trying to do as much of this mini electrical restoration as I can and I keep running into electrical gremlins.

The horn does not work and it's clear there are 3 male spades on it not being used.

The picture below is of 2 male spades and then a red wire just exposed.

Can someone please post a photo of the color wires on the horn relay so I can at least make a successful attempt at getting the horn to work without shorting the relay.

Thanks for all the help board, I'll post back to confirm it's working again so future searches have positive test results.

69 Horn

Damn, I think I found Horn wire 3 the black one, then found horn wire 2 the greenish one. The greenish one on terminal 2 would click when it touched the terminal.

But I can't find the black/pink wire that goes on terminal 4 (top), damn. No horns but I'm getting close.

Thanks for the tips, I'll eventually get my guys at Blackdog to complete this for me. Gotta honk the slower cars to get outta the way. Hahaha

This shows up to 1968 and then from then on with part number ending in 75.

I have 2 wires factory color and the rest are spliced into, damn. I'm gonna see if there's a way to get a horn wire kit that I can get and redo it like factory. 👍

My 68 GTO, built 05A has the newer 875 relay even though the older relay replacement was effective June 1 '68. No evidence of the older relay ever being installed.

Thanks for that, I have the power seat and now know that combo wire connector is for that. Great

Its borderline disturbing how many accessories can end up feeding off that one orange wire.
I'm sure there have been plenty of melted connectors back in the day.

Here’s another pic of horn relay and wire connections. I have power top, windows and seat. The orange wire and dash harness are original. Engine and all front end harness are repops from M&H.
