CompuStar option button 1&2 with a relay

I need to drive a relay 12v  relay with button 1 or 2 on my 2way remote.  I have a 2WSS-AS in my truck. I need it to toggle (latch until i push the button again) each time the button is pressed.   I can't find my manual to see if this is just something i can change the brain's program.  If i'm remembering right it can either toggle or momentary contact depending or what it's pregram is set at?  Mine is still set to factory default whatever state that would be.  ANyone have the web address to see the program manual and  the wireing diagram?  If memory serves me right the connector for the button 1 and 2 are (-) right? I could look at the brain but it's crammed under the dash right not and a little too cold to dig for it.  haha  Thanks for any help.
