I'm a little late to my own party, but I did finally install the horns on my Lincoln:
Like the English Chap, I managed without drilling any new holes, although some locations are currently less than ideal. My 20 amp circuit, however, has been sufficient so far. The Delco Remy horns are from '80s Cadillacs or Buicks - I can't recall at this point - so they ground through the mounting bolt. At some point in the '90s I believe they must've switched to a two wire setup. But the Lincoln's fenders are already grounded for the stock horns, so the single wire horns weren't a problem. It also made for simpler wiring. I grabbed the horn 'harness' from an '80s Eldorado to swap out with the stock wiring from the point of the header panel connector, near the factory engine bay relays. GM used a slightly larger wire than Ford, but since they're both 20 amp circuits I'm just going to run the stock wiring from the connector back and not worry too much about it.
Three of four Delco Remy horns. The fourth note came from a different model Cadillac, and while it was still a one wire unit, the mounting bracket was a little different. They all had tabs to help locate them on the fender, and as I assume the English Chap did, I ground them off to make a flat surface for my own car.
Right two horns. One is obscured by the header panel and battery, but you can see the mounting bolt just above the battery's positive terminal, as well as the green horn wire snaking through the fender.
And the left two. The Eldorado harness just barely stretched between the horns mounted in this way.
The stock notes are high 'A' on the passenger fender and low 'F' on the driver's side. Ford mounted horns from below, while GM liked to mount from above. Without drilling new holes, finding workable locations meant some compromises in orientation. I put the new 'A' and 'F' horns in their stock locations, but pointed forward instead of down. 'C' and 'D' were bolted to the header panel, with the 'D' horn being the only one to actually point down, but at the cost of being closest to the ground. Whether any of these locations or orientations cause shorter lifespans for the horns remains to be seen.
Finally, just for the hell of it I pulled out my piano tuning app while testing each horn and took stock of where each one was relative to its nominal note. All four of the Delco Remy's were between 4-10 hertz sharp, and if I ever find myself with absolutely nothing to do one day I might try to tune them.
C - 523 hz - I couldn't get a good reading on this one
A - 440 hz - 450 hz actual
F - 349 hz - 356 hz actual
D - 294 hz - 290 hz, slightly flat
