Compustar CM-800 Blue Wire?

Hello all,

I'm installing a Compustar CM-800 in a custom build Jeep MJ that has a 1993 Jeep XJ wiring harness. My question is on the CM-800 connector 1 pin 5 blue wire. I'm not sure if I need it, see below. I'm assuming I don't but I'm not 100% sure and if I do what would it go to? Thanks!


Connector 1 (CN1), 8-Pin Ignition Harness

Pin 1 Red - Constant 12V positive (+) power input. This wire must be connected. The proper vehicle
wire will test (+) 12V at all times - while the key is in the off position, the on position and during
crank.

Pin 2 Green/White – This is the positive (+) parking light wire that triggers when you lock and unlock
the doors and remote start the vehicle.

Pin 3 Red/White - Constant 12V positive (+) power input. This wire must be connected. The proper
vehicle wire will test (+) 12V at all times - while the key is in the off position, the on position and
during crank.

Pin 4 White - Accessory 12V positive (+) output. This wire must be connected to the vehicle accessory
/ HVAC blower motor wire. The proper wire will test 0V with the key in the off position, (+) 12V
while key is in the on position, 0V while cranking and back to (+) 12V when the key is returned to
the on position.

Pin 5 Blue - Positive 12V (+) output that powers up during remote start. The behavior of this wire is
selectable by a jumper inside the control module. By default this wire powers up as a 2nd Ignition
trigger. It is changeable to a 2nd Starter or 2nd Accessory.

Pin 6 Yellow - Starter 12V positive (+) output. This wire must be connected for remote start. The proper
wire will test 0V with the key in the off position, 0V while the key is in the on position and (+) 12V
during crank.

Pin 7 Green – Ignition 12V positive (+) output and input. This wire must be connected to the vehicles’
ignition for remote start and valet / remote programming. The proper wire will test 0V with the key
in the off position, 12 V (+) while the key is in the on position and 12V (+) during crank.

Pin 8 Black - Ground negative (-) input. This wire must be connected to the vehicle’s ground.

Forgot to say it's a 1988 Jeep MJ with a 4.0 that's out of a 1993 Jeep XJ and we are using the wiring from the XJ as well the build is heavily modified.

That thick Blue wire is typically used to power an extra ignition wire. If your Jeep only has one Starter, one Ignition and one Accessory wire, then that Blue wire is not used.

Soldering is fun!

Thanks for confirming my assumption.
