Guardian 911, 1988 Ford Bronco

I have a 1988 Ford Bronco Eddie Bauher and Just installed a Guardian 911 security system, every thing works great but i cant figure out how to hook it up for the keyless entry. on the security system there is a 3 prong plug with 3 wires for the door locks (red, blue, green). According to the manual i have what they call  a 5 wire reversal rest at ground system.  What exactley do i need to get my keyless entry to work? Can anyone help me get this thing working? This is exactley what it says:

"Examine the wires on the back of the switch. Normally 5 wires will be found. Of the wires, one will be constant 12 volts positive, regardless of the switch position. Two wires will be grounded regardless of the switch position. Of the 2 remaining wires, one will show 12 volts positive when the switch is pushed to lock and the other will show 12 volts positive when pushed to unlock. When the correct wires are found, they must be cut."

What next? Do i need relays for this type lock system? Im really dumb when it comes to this stuff. Like i said the entire alarm is installed execept for the keyless entry . can anyone please help me?

Hope this helps.

We have a 1988 Ford Bronco. I installed a security system on this truck but I dont like the siren. Is there a way I can do away with the siren and use the horn for the security siren. How do I go about doing this?
