I'm not a professional installer, but I've installed dozens of alarms and multi channel modules in my time. I've got one that's throwing my for a loop though. So I need help.
I've got a 99 Taurus. It's my daily driver. The car has power door locks, but was not built with any factory keyless parts. I want to be able to work the door locks with a remote. Don't care about the alarm portion, or light flashes, or horn honk. Just want remote door lock operation.
The car uses a lock and unlock relay under the dash, that receives a negative signal from the GEM module to activate the relays. I verified this by grounding each of the two wires, which resulted in the door locks locking and unlocking. My plan was to get a simple receiver that outputs a negative pulse, and then tap into those two wires from the GEM module to the relays.
The first unit I bought was a cheap $15 Bighawks keyless module. I wired it up and it you could hear the internal relays clicking, but nothing was being output. I figured it was just a cheap unit and wasn't working.
So I sprung for a DEI made unit, and chose the Avital 2101L. The 2101L says it has internal relays that can directly run door lock actuators. A nice feature, but I don't need to go that route since I have factory lock/unlock relays. So my plan was the same.... trigger the factory relays with a neg signal from the keyless unit.
I wired the 2101L like this... H1 (red) to 12+. H5 (GN/BLK) to the lock trigger wire from the GEM to the lock relay. H8 (BL/BLK) to the unlock GEM trigger wire. H7 (P) and H9 (P/BLK) to ground. H11 (BLK) to ground.
My understanding is the relays in the 2101L work like a Bosch 5 pin. H7 and H9 are your source inputs (circuit 87, going to ground since I want the relays to output neg). H5 and H8 are your outputs (circuit 30). Circuits 85 and 85 are internal to the unit. 87A should be not used.
But when I wire it up like this, I don't seem to be getting any negative outputs to the wires going from the GEM to the lock relays.
Am I missing something here? Do I not have it wired properly to do what I want? Or should I be installing this unit a completely different way?
Thanks for any help :)
