So after replacing the main engine wiring harness and re-wiring both ETAs I took my 1994 SL600 out for a test drive today. ASR light still on and car still in limp mode. I could have lived with that and started looking for the next problem but on the way home I hit a bump and my horn came on and won't turn off! Luckily I was only a few block away so it was a short, slightly embarrassing ride home.

For now I will probably just disconnect the horns until I figure out if I can get rid of the ASR issues. Anyone know the best way to do that? The fuse seems to control a bunch of stuff so doesn't seem reasonable. Is there a connector that is reasonably easy to get at to just disconnect the horns? Where are the horns?

Thanks in advance.

Disconnect the fuse for the jammed horn. The fuse is usually located on the underside of the dash just beside the steering wheel. Just remove the cover to expose the fuse box. If this doesn't work try disconnecting the horn's wiring found in the car's hood or just disconnect the car battery. The horn may need replacing already. Have a mechanic check it just to be sure.
