Default 1980 pace car horns

I am wondering if any one can provide a picture of the two horns needed for the 80 pace car

I need to see exactly how they mount

I have 1 wire with 2 female leads and that is it

F body warehouse shows 1978 to 1981 A note and F note total of 2

Also if any one has the 2 horns for sale

As always thanks again

this shows the general mounting location, theres a small ear on the horn bracket that goes into a hole in the center bar to locate it, the bolt goes in from behind. & make sure the bolt hole threads, & metal area under the bolt head are clean metal, that show they ground. & i suggest buying a GM service manual, it has almost all the info you need to work on or restore the car. can buy them on CD for about $20 on ebay or other places.

the wire has a jumper on it for the other horn, connector with 2 wires in it goes to the pass side horn.

they are A & F.

i have a bunch of horns but havent tested them all yet since pulled off parts cars. i can test some if you dont find good working ones elsewhere.

I've noticed that one horn mounts straight down, the other turned about 5 degrees. I'm not sure if this is intentional or correct, just those I've bothered to notice.

GM Delco replacement horn part numbers:

Low "F" note horn 1892163

High "A" note horn 1892164

Some cars used:

Low "D" note horn 1892162

High "C" note horn 1892246

The parts book didn't specify which models receieved which note..

https://www.ebay.com/itm/39323980717...AAAOSwl2pgcOBQ

https://www.ebay.com/itm/26505739842...IAAOSw1EFgLUGd

These are the correct horn bodies, but as with all NOS Delco replacement hoens have a universal bracket with a threaded boss spot welded to the horn body. You CAN drill the spot welds and R&R your original mounting brackets by rewelding them to the horn body..

The horns both have two prongs for aligning and a single bolt hole. They come as a left and right assembly. And they simply mount onto the face of the plate that is part of the core support bracket that has 6 holes in it.

The horns actually have a nut that secures them to their mounting brackets but normally don't come apart. That possibly explains why one side also turned slightly as nipped up tight by hand.

Default Question

Does the main front wire harness for the head lights etc.

Go in front of the main bracket engine side or

Does it run behind the bracket nose of car side

The reason I ask is mine is on the nose of the car side but I see a plastic harness clip on the metal bracket that looks like it is for the harness

Thanks

Will send a pic when home later. Do you have the 1980 Assembly manual?
Headlight loom runs along top, horn harness uses retainer behind upright.

Not sure why I've added convoluted tubing over the hood cable. From memory it was damaged on each end and the tubing helped keep it to a smooth S shape to operate, it's gone now, only just noticed that. Funny looking back at photos and picking up errors or things that weren't quite done.

I noticed that the part of the latch that bolts to the header panel is natural

I am going to believe that is factory

great information for my detailing

The latch is normally blackened housing and gold cap plated workings, both of which fade back to a grey metal over the years. Mine is still plated but looks silvery grey in pic. The cable retainers were also blackened normally, I had one that had plating, appears to be the one in pic.

From my 1977. This is an NOS unit. Gold cadmium plated mechanism parts and black phosphate dipped main body. It has a dark grey crystalline appearance. That hood cable clip was also the same black phosphate dipped.

John, a few more original pics from 77-78 models, 80 should be the same. Note the wiring harness on these run down to the square retainer clip near the horns and back up.
