00 mercedes c230 locks

Hi, I am installing an alarm into a 00 mercedes c-class I am using the directechs map and the locks are supposed to be in the driver door module or at the pump module in the back (black and blue negative trigger) but I can not locate them at either location. I was wondering if anyone has any info or suggestion to finding these lock wires? Everything else is done (triggers, trunk release, etc) the only thing left is the locks. At the pump module in the back I got all my triggers and my trunk release, there are only 3 wires left (aside from the power wires) but I cant seem to get any signal from them for the locks. One wire is the dome light wire (BROWN / green) and then there are 2 twisted pair wires (one brown one BROWN / black) that rest at ground and I cant seem to get any signal from them when using the locks.. can anyone please help? Thank you very much

Does anyone have any info to help? Thanks again

i dont know much about benz but i know that the locks are probably vacuum operated, single wire, i ran into that a couple years ago on a 300E. sorry i cant help much more than that.

Very hard to find, this is for right hand drive (UK) so mirror this, also, only used up to '98 so it might be can system, 2 ways:- 1)  Go to wiring conduit at carpet edge and look for a sub-loom joining main level with front of driver chair coming up from floor. The lock wire may be extended for close and both neg. make sure door shuts are pushed over, you might also disconnect door contact switch to be safe, and remove key from ign.  (all to emulate closed door) 2) Go to switch on dashboard, white green or green white (not sure). Again neg but neg to lock and neg through 200R resister, if low current lock outputs boost with reays both sides,N.B. might be other way round, TEST.
