along with you its been a few years since i did major installs... after thinking about it you shouldnt need to add resistance to the headlight circuits off of the alarm module... and the relays should wire right inline to the exsisting lock unlock circuit.. its funny when you dont do something for a few years how much you forget.. if you gimme the model number and more details i can do more homework.. i still got good contacts with other intsallers that are WAY better than me..
