85 cab wiring questions. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I replaced the cab and front clip on my 74 with ones from an 85.

The steering column was hacked and a push button was installed for the starter. I replaced the column with a good one and everything works as it should, but the neutral safety switch is bypassed and I can't find where the wires for it have been spliced together. Where do these wires enter the under dash harness, or where do they go?

The horn also does not work. Where should the horn relay be located?

Hi

I'm a novice so this could be wrong, but you might look at thing shown in the fourth photo in this post. http://67-72chevytrucks.com/vboard/s...15&postcount=3

I can tell you the poster of the photo and text didn't know what he was talking about because it was me.

In my case it wasn't the relay. It was a simple fuse in the fuse box.

I have the horn problem figured out. The turn signal cancelling cam is broke where it holds the wire for the horn button.
