Hey everyone, hopefully someone can guide me with my problem.  I took the task of installing a remote start/keyless entry this weekend.  The remote start part is finished and works fine but I got stuck when it came to patching into the door lock wires behind the glove box.  I took it out but did not see those specific wires, I will look again tomorrow.  The other issue is that the RS is for negative locking systems.  According to what I have read this does not work with BMWs but I have not found any clear information on the subject, only wire colors.  I was supplied a DEI 451M but it came with no instructions.  Can anyone point me in the right direction?  How do I take this 451 and supply the correct output to the locks from the negative trigger coming from the RS.  Is it as simple as hooking the RS to the 451 and then patching the correct wires from it into the locking system?  Thanks in advance.
