Need help I am truly stumped w/ dome lite

To you gods of cars,  This has me just perplexed.  On a 96 chevy blazer, I have installed an impulse alarm w/ remote start.  Once the install was complete, The dome light came on and would only go off if The blazer was remote started.  Starting with the key would not turn off the light, and the floor lights are on too.  Once I killed the RS, If i open the back door, there is no problem.  The light comes on and then goes off when the door is closed.  Once I open either front door, the dome light comes on and does not go off again until the remote start is engaed.  I did not hook anything up for dome light supervision. 

The blazer has factory installed keyless entry

What has me realy stumped is I cut the wire going to the door pin and it had no effect on the problem. 

Please help!!

Drive it like you rented it!!

Ok this might be a solution, but don't quote me on it.

Are you using a white wire as your door trigger? If not I'm stumped...

If you are however, the white wire reads a domelight delay, what you need to do is install a diode inline your connection to the trigger. To keep the alarm from reading the delay, place a diode in-line on the white door trigger wire with the anode towards the white wire. Attach your door trigger wire to the cathode side of the diode.

You may be getting feedback which might keep the light on.

Just my 2 cents.

thanks for the help....   I dioded the line and replaced the door pin that was faulty and all is good.

thanks
