if this vehicle is a 6.6 diesel the wire for the glow plug light can be found behind the instrument panel

and is blue with a negative signal.

most remote starters accept his input signal.

if the vehicle is equipped with factory keyless the doorlock/unlock wires will be positive

these are normally

lock----light blue drivers kick panel

unlock----white drivers kick

PCM, blue plug, pin 52, lt. Blue (+). This is the output from the glow plug relay. Here is some additional info but there is conflicting information on this that has not been validated

found wait to start behind the cluster, dk. Blue (-) there is no wait to start light on this one
it doesnt need to wait.

This information was from a previous post from another member, so please verify this with a DMM.
