avital 2101

I installed an Avital 2101 Keyless in my 94 Mustang GT. I have everything hooked up but trunk release and horn honk. They both are a negative 300ma trigger output. I used relays to change polarity to positive and it still will not does not work. I am using a siren instead of horn honk but when I trigger remote I still have no output when testing after the relays with test light. What am I doing wrong?

The horn is a straight (-), Yellow wire to the right of the steering column.  Relay conversion to (+) isn't needed.

The Trunk Release is (+), Purple / YELLOW low in the Drivers Kick Panel.  Wiring for the relay should be:

Relay Pin 85 to Avital Trunk Release OutputRelay Pin 86 and 87 to +12v constant thru 20A fuseRelay Pin 30 to Mustang Purple / YELLOW Trunk Release wireRelay Pin 87A not used - insulate

Soldering is fun!

This is the way I wired the relay, i got this from this site pin 86 & 30 to fused 12 volt + pin 85 to negative trigger pin 87 to trunk wire pin 87a not wired are they wrong

here is the link to their diagram https://www.the12volt.com/relays/page1.asp

Kreg and your relay diagrams in this case are BOTH correct but I would modify them to retain the circuit and protect your alarm's circuitry. Cut trunk release feed, then: Switch (front end) side to 87a. Trunk side to 30. RED / white from Avital to 85 via a 1N4004 diode, band towards relay. Constant 12V+, fused at 15amps to 86 and 87.
