03 savana urgent

I'm now working on 2003 GMC SAVANA for remote starting. I bought a 555L for PASSLOCK 2. But I don't know the color code for the wire I need to connect in the car. Please give me urgent help ! Many Thanks !

The directions for the 555L should come in the box with it and have the wire colors you need to know

Not sure of RS installed:

555L:Red = RED Constant at Ignition SwitchPink = PINK at Ignition SwitchBlack = ORANGE / Black (or Black) PASSlock reference wireYellow = YELLOW Key side of CUT PASSlock wireBLACK / YELLOW = YELLOW BCM side of CUT PASSlock wireBlue /Black = Negative Output while running from Remote StartIn your Ignition Switch harness you should find a thin Yellow wire and a thin Black / Orange (or Black) wire.  These would be your PASSlock 2 wires.You will cut the Yellow wire in half.Follow your 555L instructions

i know what you are going through. take the column apart and look at the back of the key cylinder, there are 4 wires, green,beige,yello,black, the yello and black are the passlock 2 wires you need, also DO NOT go to any other sorce for a tach signal....especially the computer under the hood near the front of the van, it may work fine but give it a week, all sorts of codes set off the engine and abs lights, and eventually prevent the van from starting. go only to the purple of any one of the injectors.....it is more awkward to get at but well worth the headache saver.sweet.
