Notes:

*1 The coil wires exit out of the rear center of the cylinder head.  *2 Use both and diode isolate each.  The PURPLE / red is in the drivers kick and the purple is in the passenger kick.  *3 To interface with the negative ignition wire to remote start, see directfax document #1500 for wiring information.

You can just make a few modifications to the Viper's existing relay pack. Follow the two thick red wires, the ones with the 30-amp fuses. You'll see that they go to terminal 30 on all the relays, and then there's a thin red wire with a 3-amp fuse; this goes to terminal 86 on all the relays. Reconfigure things so that 30 on all the relays sees ground, but all the 86 terminals still see positive. Now, your pink, pink/white, orange, and purple wires will function as negative outputs. However, there's one more thing you must do. For a number of reasons, the brain of the unit must know when the car's ignition is switched on....this is what the thin yellow wire in the relay pack's ribbon harness is for....but this wire is looking for a positive input. You can add another relay to convert your car's negative ignition wire into a positive, and then tie the output of the relay directly to the thin yellow wire. (You would cut the yellow wire away from its current spot in the relay pack.) Or, see if you can find a positive ignition wire elsewhere in the car---maybe you'll find a source of ignition at the fuse box...and then you can tie the thin yellow right in there, without the relay.
