Re: [Chevelle-list] Horn Relay Hook-up on 66 Chevelle

[Larry Shouse]

Thanks to everyone who responded. David Hanks and Ed Riggins were both able to tell me the correct connections. After many emails off list between Ed and I last night, we figured out what caused this confusion. M&H wiring harness seems to be manufactured correctly, but the AC Delco $50 horn relay terminal had the raised "key" stamped onto the wrong terminal (on the unused #4 terminal).   I verified our findings this morning by ohming out the relay and then hooking it up to a battery for proper relay operation.   One step closer to bringing this car back to life...   Thanks Again, Larry Shouse  ----- Original Message ----- From: Larry Shouse To: Chevelle List Sent: Wednesday, April 19, 2006 5:30 PM Subject: [Chevelle-list] Horn Relay Hook-up on 66 Chevelle Time to pick your brains again...   Please take a look of this picture:  http://www.fuglybrothers.com/images/horn-relay.jpg   It's a picture of my brand new, upside down  $50 horn relay (subject for another day). I need help with the connections. Here's what I think I know. Please correct me if I'm wrong, and fill in the spots I don't know...   red wire - 12vdc goes to battery through the junction block, and a few other places. Hooks to terminal 5 (spade) as I have them labeled.   black wire with white stripe - goes to fuse block on firewall. Hooks to terminal 3 (spade) as I have them labeled. (tied to 5).   double green wires - 12vdc going to the horns when relay is energized. I THINK it goes to terminal 1, but not sure.   black wire - I think this is the horn ground, which completes the relay circuit, which applies 12vdc from red wire to the double green. I don't know where this hooks to.   When all pictured wires are connected, if my count is right, there will be one terminal unused. What goes there?   Thanks for your help.   Larry Shouse
