I've been searching the forums for the answer to this, but was unable to find it. This is probably one of the easiest uses of these parts, but I want to make sure I understand everything before I operate.

I am going to trigger the pulse timer off of the factory keyless entry system (the wire which corresponds to the lock/arm function) The pulse timer will send a signal to the widow module to roll the windows up.

The only part I am really confused on is the pulse timer wire configs.

Which wires do i connect to the window module. I know how to use the +/- and trigger but here are the others:

Orange 87A (normally closed)

Brown 87B (normally open)

Yellow 30 Common

My assumption is that i will use the orange, but what does the common do?

Thanks in advance for your help!!!

First you'll need to find a wire in the car that either goes to ground momentarily when you lock the doors, or goes to +12volts. Then, the BLACK/ white wire from the 528t will goes to that wire. The red off the 528t goes to constant +12volts. Black and Brown both go to ground. Finally Yellow gets hooked up to that tiny orange wire off the window controller. As for the blue loop, if the wire in the car that switches goes to ground then leave it alone. If it goes to +12volts then cut it and isolate the ends. The orange wire on the 52t you will not need.

Cause I'm So white and nerdy...

oh, and also - what is the easiest way to use a multimeter to test all of these wires? Do i have to find a point of termination and test there? or is there an easier way

Whats the make/model/year of the car?

You can typically strip back the wire at a point its easy to test. If its not the right wire just wrap some electrial tape around where you broke the insulation and move on.

I am supposed to use the Brown (the normally closed). Does this mean that it should go to activate a circuit that is normally closed? I'm kinda confused.

is this true with this?:

When the coil of the relay is at rest (not energized), the common terminal (30) and the normally closed terminal (87a) have continuity. When the coil is energized, the common terminal (30) and the normally open terminal (87) have continuity.

Yes this is true for the 528T. It is basically a standard relay but with an adjustable timer on it. It functions the same as what you described. It holds the connection open or closed for 1-90 seconds. The common you asked about is a wire that is common to both the open and closed wire. You always hook one side of the wire your connecting or disconnecting to it. The other side of the cut wire goes to either the normally open or normally closed wire. If you want to supply the yellow window module input trigger wire with a ground for a period of time. You hook the common to ground and the yellow wire to the normally open wire. This way when the timer is triggered by the lock the adjustable timer triggers the window module wire for the amount of time it needs to roll up all the windows and then disengages the trigger wire after the timer elapses.
