They are a significant improvement in volume and attention getting.
Although I have a seperate wiring harness, relay and fuse for them, I have started by just using the stock wiring. Specs say they draw 66w or about 5.5A at 12v. The OE horn fuse is a 15A fuse, so I am hoping the circuit will handle it without issue. If not, I will wire in the dedicated relay and fuse later.
well aren't you special,nice set of horns.
Nice going Ken, thanks for flogging this ride,
it always seems to come back for more,
and to think it has over 200K miles on it

Update on this:
I did go ahead and add in the relay with a direct tap to to jumper post under the hood. I didn't feel I was getting the full volume effect, and wanted to make sure the horns were getting as much voltage as possible. Bolted the new relay to the old horn mounting point and used heavy gauge wiring with soldered connections where possible. I also reinforced the mounting with secondary brackets.
Needed to address two HVAC issues before it got too hot this summer. Note: The system is still R-12 and still blows very cold.
1. I was dealing with the all/nothing issue for A/C. The moment I moved the slider off coldest setting, it mixed in full hot air.
2. The blower motor was really starting to squeal, squeak and chirp. I had lubed it before as a temporary fix, but I knew it was planning on dying on the hottest day of the year
The all or nothing issue was broken sensor wire for the sensor in the alternator hose. I don't have a picture of it fixed, but it involved pulling out the connector pin and re-soldering, then adding strain relief to prevent breakage in the future and a good dose of shrink tubing.
For the blower motor, I bought Rogers blower motor upgrade kit combined with the heavier duty wiring harness from Greg Brown to handle the additional amperage. General notes:
-It may be possible to remove the blower motor with the hood still on, but I don't see how;
-Eternal curses on the Porsche engineer who put that one blower assembly screw in the blower opening where it is impossible to reach directly and the screw drops into the bowels of the blower if you slip;
-the Greg Brown electrical harness was straightforward;
Getting set up, with the blower out:
Old motor, look how far down the brush is in its travel. End of life:
Cage off to be re-used. Used old rotor as working surface:
New motor installed, with just a smidge of axle poking out:
Working with the 8-Pin connector per GB instructions
I replaced my left front splash guard while I was in there with a nice used one from 928 Intl ( new is NLA ), and while waiting on that part, ( idle hands are the Devil's tools) decided to clean up my hood latches.
The top latch went fine:
The bottom latch needed love too:
The bottom hatch went..not so fine.... It turns out the set screw for the cable on that was broken off, so I had to drill it out. I have about a 25% success ratio with "easy-outs", and this exercise did not help that ratio.
I eventually drilled out all of the screw, but destroyed the cable in the process:
A fresh cable from Roger, and little fun with powder coating, and I was good to go:
Sorry if this has been answered...I couldn't find it. What wheels are those...the black ones on the car? I know I've seen that style, but I don't know that I've ever seen them in black, and I'm constantly looking for what looks good in that color for when I get around to upgrading my stockers...
