dei 530t

Thanks again for the reply. This is just a diagram I drew up on ms paint. The vehicle I am working on is a custom wiring project so there is no true vehicle diagram. I will be basing the design off a 2002 pontiac firebird. I plan on using the factory alarm and keyless entry system to trigger the 530t. I will use the trunk pop feature of the remote for the aux channel and the bcm i am using has a ground when armed output. Aux channel for vent and gwa for windows up alarm armed. You are correct in that I plan on using a 528t with this configuration. If appropriate i can draw up a complete diagram and submit it for review.

Good, PM me with your email address, I'll run up a diagram sometime today and email it back to you, bare with me because I'm 5 hours ahead of the Eastern Seaboard.
