Default Help Request | Electrical Relays | Novice

Vehicle: 1970 Corvette
Goal: Fix horn


1 - Can someone tell me what this circled in photo is for? Red wire goes to horn relay; not sure yellow. I have the AIM but not seeing any pages on it.

2 - , I replaced the relay which got it working except when battery is connected is goes off which I assume is a grounding issue. I wired it up per diagram and now doesn’t go off with battery connected but also doesn’t work with wheel button pressed. The steering wheel button parts look good.

What could I be overlooking?

my chevelle had a ground wire in the steer wheel button but watching videos didn’t see anyone else with a c3 have one.

3 - per the other image - the relay originally when I got it had two wires going to the left screw and two more red wires going to the right screw.

in diagrams original image in white text it just shows one wire to each.
