Keyless entry installation help

Hey guys, im having some difficulty installing keyless entry in my 1990 300e. I purchased an OMEGA EXCALIBUR REC-43T it requires 2 relays to run our vacuum system. I have it wired up like this http://www.bulldogsecurity.com/diagr...UM%20LOCKS.pdf

I have researched this subject and have seen installations of these systems under the dash, under the rear seat and at the trunk lock. The easiest I think would be to do it at the trunk lock actuator. I have it wired up and the power on the unit comes on and I can program my remotes. So i know the power/ground is ok but everything else is obviously wrong because it isnt working. Does anyone know where I need to go from here and which of the 3 wires going to the trunk lock i need to use?? Any help would be really appreciated.

Try this guy:
stereoinstaller1@gmail.com

He might help you - he's very active on other forums.

He just wired up my W124 500E, last weekend.

Door locks and lights work perfectly, nice job.

It would be helpful if you could provide him with whatever wiring diagrams you have.

Good luck.
