99 Integra Keyless Entry

Well I would imagine you could diode isolate it and run it to another relay where you could wire it for negative output. Have a look at the relay section here as well as the diode section and it should help you.

OK, so since my lights are + trigger, and the horn is a - trigger would it work to hook another relay up like so:

85 :spliced from trigger wire from unit

Hey guys, I've been having some trouble getting the horn to work right.  The relay doesnt seem to be wired right so I guess I'm doing something wrong.  I tried hooking it up like the following, and didnt get anything..

30: Ground

In theory it should work - I can even feel the relay click.  When 12v is applied to 86, a connection should be made from 87 to 85, grounding the horn wire which is all that should be needed to get it to honk.  Am I doing something wrong guys??  All your help is appreciated. 

OK, heres for future reference.  The wireless/keyless unit is actually grounding the wire already so heres the answer..

86: signal wire (its actually -)

That worked like a charm - only trouble is now I need to reduce the time the relay is open (horn is too annoying).  Like the capacitor idea stated previously.  Could anyone elaborate on that one?
