So today I had an old, broken alarm removed from my 1988 Prelude.

Everything was good afterward. The car doesn't seem to have the electrical issues it had so much as it did when that horrible alarm was in there.

Two problems though. I haven't looked much into them yet because it got dark out.

Headlights
I went to turn the headlights on and the headlights didn't pop up. I checked and my taillights work perfectly. My brake lights also work. The headlights do pop up if I used the button to make them do so, but the headlight combo switch doesn't make it work. So the headlights don't pop up and also don't light up.

Horn
My friend's little boy was beeping my horn, which I'd always thought was single tone, and suddenly a deeper tone came in too (dual tone? since when?). Soon after it stopped honking altogether. I read the horn and brake lights are on the same fuse, but they work.

The dash is still torn apart after the alarm install. The two relays or such on the the kick panel are currently plugged in though (I know one is probably a dimmer relay, judging by if you unplug it the dash lights stop working). I saw a small blue plug (6 slots, only saw 2 contacts in it though) hanging freely. I don't know if that's what the problem is with the headlights, but perhaps that needs to find it's home?

Still unfamiliar with the vehicle... Thanks for any help.

 

Figured it out. I didn't notice since it was dark. The big green plug was unplugged still. lol

Well, at least if anyone else screws up, etc. then this thread is here to help.
