Im looking to install a Compustar DC3 in my 2004 Ram 3500. I looked over the idatalink install guide and it shows 2 relays used and one 330 ohm resistor. The resistor appears to be for the parking lights. Looking through the posts here I have read more relays and resistors will be needed for the locks. Is there a wiring diagram for the DC3 that shows relay connections for the locks?

the dc3 has a door lock mux wire that should do the lock/unlock. yellow wire m4 and hooked to purple/ltblue in the drivers kick panel. shouldn't need a relay
31 years as a installer. Favorite thing to install/topic are remote starts/car alarms. Stop using test lights!!!
