does anyone have any info for this car? i've managed to do almost everything....door triggers, parking light flash, tach, remote start, but i cannot find how to do the pwr locks. everything else about this car is almost identical to the current 3-series bmw, and the dei 555b or the factory bmw key ring antenna work as normal. even the module behind the glove box looks identical. but strangely enough, i can't trigger the door locks. anyone with some experience on this vehicle or technical info to help me out?

thanks in advance!

those are the wires that i've tagged, but for some unexplained reason, it doesn't work. i've made sure all the doors are closed, ignition off, no key in ignition barrel, etc. i must be off my rocker or something, because those wires work just fine on all the other 3-series vehicles. i don't have an explanation. thanks for your responses though!

i have recently done alarms on the 3 series and had some trouble with the locks i found that the negative pulse on the wires to lock and unlock the doors had to be very strong and ended up using relays to strengthen the output also the doors must be closed which you said you did so check the strength of the lock outputs good luck
