I purchased the HT800D from Ebay. I've installed the options I want, however I can't seem to figure out how to hook up the power door lock/unlock feature. There are two wires that come out of the unit, one for single pulse the other for double pulse. My daughter's vehicle is a '95 Eagle Talon with a negative trigger for both the lock and unlock feature, on seperate wires. How do I tie the single pulse trigger into two (2) different lines? Any suggestions? Thanks in advance.
