530t window module

how do i control the windows down

i have a 791xv alarm, the trunk pop is hooked up to channel 2

channel 4 and 5 are open for use,

must i use a inline relay to activate the window down function or can i just hook the modules up to the 4 or 5 channel output off the viper

if a relay is to be used please diagram it for me if u can as i am new to all this

this is for a 96 impala ss

also, which settign should channel 4 be on validity,latched, lathced reset ignition

Chanel 4 OK to replace chan 1, set pulsed validity, remember though you have to hold it a few secs before it works!
