Calling all aftermarket keyless entry gurus
 

I have read as much as I could online but have not found anything concrete. Not sure if this is the correct place to post. I'm just a little stuck and don't want to mess anything up. I purchased a very simple and inexpensive keyless entry system for my w201 190e 2.3 16v. I am a little confused as to which wire I should connect my yellow lead from the keyless entry to blue, green, yellow on vac pump! Also there is a gray that goes to a "motor switch" which is connected to the air compressor which apparently needs to be cut? No idea if I'm reading that right? I have uploaded a diagram here. An annotated in the red box what I have followed. Here is what I am reading:

yellow/black - 12v+
yellow - blue, green or yellow on vac pump?
green and brown - connect to each other
blue - ground
gray - ? motor switch ?



I know there is a plug into the pump with the blue, green and yellow for the right left and trunk locks.

There is also a plug with a brown and red into the pump. I assume that is 12v+ and the brown is my common wire from the motor switch?

Is that the wire I then cut and connect to the gray?

Got it figured out if anyone needs help! :)
