2008 dodge 2500 parking light trigger

Installing a compustar remote start with EVO-CHR bypass module. I am new to this multiplex system and dont get the whole ground through resistor to relay. So does that mean i branch(splice) off from the WHITE/ green(parking light negative) wire then put a resistor in series to 85 of the relay and complete the rest of the relay as normal, 12 volts to 86 and 30, then 87 output to alarm module? Thanks in advance.

If parking lights from car is negative( cut this wire) 85 WHITE/ green 86 12v.- 30 ground with resistor 87a to switch side of wire cut-from pl. 87 to parking lights(pl)

85 I mean parking lights negative output from alarm

Appreciate the info.
