I am installing an alarm/starter combo in a 2004 chevy express van 3500 and I was wondering if anyone had a wiring diagram. I have a 2003 diagram but this install needs a Passlock II and the diagram I have does not coincide with the 2004 van. My wire colors are ORANGE / white, yellow, and tan. I don't have the yellow, ORANGE / black, and black. I am having trouble with the passlock II wires and the tach wire, everything else is all set. Thanks.

What bypass are you using?

Save money by use two relays and a resistor and its the same as a bypass module and better than some modules

That is if U have the ability to DMM your PASSlock 2 and purchase the Relay & Resistor, wire it in & hope U have the right resistance. Although it may save you money, the cost is not that much higher to purchase a PASSlock 2 module considering the time it would take a person who does NOT Install on a regular basis

Best bet to buy a bypass and be done with it! .....MO12v is correct!

Use the PLDATA. It's the best module and it's sooooo user friendly with on y 4 wires to hook up. Even newbees can install this without any problems : ------------- Jeff
