96 F350 Remote Start Question

I have installed a Crimestopper Remote Start Alarm system, but can't get the accesories (A/C) to work when the rmote start is used. I hooked up the accesory wire from the m to the grey / YELLOW wire at the steering column and the fan comes on, but the A/C clutch doesn't engage. (And yes, I have the switch turned to A/C). On this site it says the wire to turn on the a/c & heater the accessoriy wire fromthe alarm should go to a blue/green wire at the steering column, but wire is like a 24 gauge wire and doesn't do anything when I connected to it, in addition, it only has 6VDC when the igntion switch is turned to on.

Any help would be much appreciated.
