using my 4th channel for rear defroster:

1st of all as for the programming. You -don't- want to use latched because it will require you to manually turn it off. Either reset with IGN or 30 delay would work depending on the defroster. If the defrost is the old style where you flip a switch and the defroster stays on until you turn off the swith then you would want to use the "Reset with ign" only. If the defroster was timed (like momentary push button) and shut it self off then you could use the 30sec timed output. Using the "reset w/ign" should be ok since hopefully the windows would be defrosted by the time you enter the car. If they weren't then you could just hit the switch to finish off. The 30 sec wouldn't ever work in that type of system. I also don't think you wired the relay right as above. 85 - positive 86 - trigger from alarm 87 - positive 30 - to switch under yours the output from the alarm would have to be (+), normally it (-).. Good luck.

i see, thanks.  that pretty much took care of what i needed.  ill play with it when school gives me a chance.
