High Low Horn question
I have a pair of high low horns laying around. My truck is a 68 so it doesn’t have the option for both horns. My question is what do I need to do wiring wise to use both of these. My current harness only has the 1 green wire. Do I need to splice in a jumper wire to the other horn off this green wire? If not can I use just 1 of these horns and does it matter which one?

Re: High Low Horn question
I've thought of doing this on my '68 as well. I don't see why splicing a jumper into the green wire wouldn't work. Not sure what the bracket would be to mount both, though - the one thing I would have to figure out..

Re: High Low Horn question
Here is a photo of my 67 dual horn set up. It uses a common factory jumper wire and plug to hook the two together. If you look close on the bottom horn you will see it. I didn't install them but I have seen the jumper on other GM vehicles.

Re: High Low Horn question
Nice I’ll give that a try. Also noticing my horn brackets are shapped a little different. Instead of having a L at the end mine are just straight. Either way I think I can make it work. Thanks for the photos.

Here's a picture of a factory jumper wire itself.

Re: High Low Horn question
I’ve noticed some core supports are pre drilled for the dual horns others not, I located a set of duals with jumper but my gmc core is not drilled for the second horn.

Here's picture of my current core support from a '71 or '72 showing the mounting positions for the 2 horns. Also note that my '69 still had the washer bottle on the core support. Most later '69s I've seen had them relocated to the fender. |

Re: High Low Horn question
I found the dual horn wiring harness on the Lectric Limited website for $20

Re: High Low Horn question
My GMC is a 71, no provision for second horn. The dual horns I located where from a 69 C20, even listed on spid.
