Default 1977 Wiring Question

OK on my 1977 Camaro, something chewed the light wires under the hood, where they go thru the firewall just under the brake cylinder on the driver's side. I pulled the plug and connected the wires back, the problem is, I have more wires than go in that plug. The lights and blinkers work, but there are four wires that I don't know where they go, there is 2 dark blue and 2 black with a light stripe on them, and they all run in the same loom as the light wires, and are about the same length as the wires that come from the plug. Anybody be able to look at theirs and see if there is something else in that area that these wires connect to.

Thanks for any help you can be.

Mystery solved, I decided to find out where the wires ran to under the hood, so when I started checking the wire loom, the wires just ran a little way and doubled back, so looks like there was 33" of extra wire, that was folded over in the loom. Anyway all of the lights are working, I just have to figure out what is wrong with the horn, that was one wire that had not been chewed all the way thru, but I cut it and put it back, and the horn still will not work, I jumped the wire to the battery and the horns worked, so not getting voltage from the button.

Thanks

You will probably have to pull steering wheel and look in there for worn out parts.

The steering wheel switch simply grounds the horn relay circuit, so if there's a break there the horn wont work. You can check the horn circuit by looking at a diagram and see what color feeds the steering column and then ground it to honk the horn. If it works with that test, then the horn button is bad. If it doesn't, then you've lost the wire that feeds the horn button.
This diagram will show you what colors the horn and horn relay use:

I got the horn working, pulled the relay and checked hot wire, it was hot, checked connection from horn button, and it was good, so then checked the relay, and it was good. Put it back together and the horn worked, relay must have been stuck or bad connection. Thanks for your help in this matter
