autopage rs660 remote start

ok, this remote start to my knowledge does not have a wire for a 2nd accessory, however, i was told that my 99 alero needs to have a 2nd accessory wire hooked up to get the unit to activate.  how do u get a system w/ only 1 accessory hookup to utilize a 2nd?

Use the first accs. wire from the remote start to trigger an extra relay for second accs.

Ground to 86, 12volts fused to 87, your 1st ign. to pin 85, (as well as to your ignition wire on your rig) pin 30 goes to the second ign.
