Default Horn relay hookup
I recently replaced engine harness on my 71 with air. I did take pictures but the pic of horn relay isn’t clear. I have 5 wires going to the 2 screws on the relay. 4 are heavy gauge red the fifth one is actually 2 wires together orange and black. I know the red ones go to the starter, alternator, blower for ac and left side firewall tcs switch I think. Does it matter which of the 2 screws on the relay all of these individually go to?
Thanks
Fred

Thanks henrikse for your quick response. I’ve checked the aim diagram but it doesn’t show all of those various wires I listed and which of the two busses they attach to on the relay. I know they all fit but I don’t want to attach to wrong wires together or on the wrong bus and burn something.

Thanks sullyman. When I expand the picture the actual hookup is fuzzy. Can’t tell which terminal wires are hooked to, fender side or engine. I know it’s a lot to ask Is there anyway you might take a closer pic of the front? Also if I traced your wires right the fused wire is ac blower, the one over the vacuum tank is to starter and the one going back into your harness with the orange and black is to alternator is this correct? The one wire that I don’t see that mine has goes to a relay by tcs box on left side of firewall by brake booster with a red and an orange wire going into firewall. Does any one know which terminal it attaches to?
Much thanks
Fred

I see the alternator wire and orange and black connection not sure what the bottom wire goes to. That does give me the location for those two. Thanks for the picture chazde.

This may work better for you. You are correct about the wires in your previous post.

I finally found out the wire in question comes from my power window relay on firewall, it has an orange and red wire. Does anyone have power windows and this relay if so can you tell me which terminal the red wire connects to on horn relay?
Thanks
Fred
