I AM INSTALLING A REMOTE START "VIPER 5101" ON A 2003 FORD EXPLORER.. I WOULD LIKE TO KNOW IF I NEED TO PUT A RELAY OR NOT..

AUXILIARY HARNESS (H2)

H2/1 (-)200mA factory alarm disarm output.. my car has a negative disarm alarm wire. do i still need a relay or i can do it without it???

I don't think you need to hook up the disarm on that vehicle.

you wouldnt need the relay, but try arming the truck and opeing the lock from inside and see if it goes off. locate that wire, and if the alarm does go off, tap into that wire and touch the end of wire to ground, and see if it turns off. if it does, you need to hook up this wire.
