Horn doesn't work- ground issue on horn button wiring.

Hey guys, first post here, I know this is the 100th horn doesn't work thread I've googled just about all of them on here lol. I picked up and 88 T-top and am having some trouble with it but I've got it narrowed down pretty far.

So far I've followed the electrical testing steps on here, ran a jumper wire directly from the battery to the horns and they operate just fine.

Fuse is good.

I've picked up the foam replacement kit from LMR.

I got under the dash and checked the yellow/green wire with a test light and the blue/white (I think) wire and the test light lit up with both of those. I went ahead and replaced the relay.

This car has the cruise control removed. If I run my test light from ground and probe the purple wire coming off the horn button wiring the horns sound. I've traced this thing all the way to the steering wheel. That means the little black wire, which follows to the copper wheel behind the steering wheel with the 3 prongs, I'm not getting a good ground somewhere. Since the cruise control buttons and horn wiring are all integrated into those 3 prongs where does the 3 prong wiring ground at? I even touched the 2 copper plates directly together with the foam removed and am still getting nothing, but and like I said if I touch the purple wire with the test light the horn works. I'm stumped.

G201 says the LH fender apron, any idea if that's inner or outer? Car has a wire tuck done on it.

Ok thanks, I'll double check it, I'm highly doubting that's it because if it was than everything else that grounds to G201 wouldn't work either. I'm going to pull the console my whole ashtray and lighter assembly are missing so they could've used that wiring to ground something else aftermarket the put in.

Ok I'll run all those checks, I just replaced the relay this week so it's already out from under the dash. Probably wire 6. 20a fuse is good.

Cigarette lighters been unplugged, just the connector sitting in the console by the mirror switch.

The cigarette lighters been unplugged, just the connector sitting down in the console area by the mirror switch, does the lighter need to be plugged in to close the circuit, if the connector is unplugged wouldn't that be an open in the circuit?

Ok everything checks out. Wire 1 honks with 12v and wire 6 honks with 12v to safety pin and ground. Time to start tracing. I'm still honking all the way up past this connector into the purple wire just behind the steering wheel by grounding the jumper wire and using a safety pin so I know the connector is good. I'm still having to ground the jumper wire this far up though which means there's something not grounding between here and the steering wheel.
