The only one I'm not sure of is 86.... connect that one to the hot wire that runs into the old horn?

The ground wire that runs to old horn don't get used?

Man I hate this

yes - 86 goes to the wire that is +12V when you press the horn button.
the old horn ground is not used.

Need to swithc 87 and 30 then switch 85 and 86. Go to howards horn website and they have color photos of the relay hooked up you can tell which post the positve battery side is hooked to.

in reality - i don't see an issue with using the old horn ground as the connection to 85, rather than running 85 directly to the battery. running 85 directly to the battery low side seems way overkill to me

5 connections:

1. low side of compressor to ground.
2. high side of compressor to relay 87
3. +12V from battery to relay 30 (I'd fuse this unless the compressor has a fuse)
4. hot side of old horn to relay 86
5. ground side of old horn to relay 85 ( no need to run this to the battery)

I agree with 87 and 30 but think you have 85 and 86 backwards by looking at the diagram.
