Doing a remote start/alarm on a 2003 Dodge Ram Pickup. For the parking lights it states that it is a purple / YELLOW in the headlight switch and is negative trigger. I'm using the directwire sheet. For the notes it states "Parking lights require a negative trigger thru a 330 or 1.4K ohm resistor. There is a rest resistance on the wire, so MUST use a relay to isolate away from the switch". First question is Which resistor should I use the 330ohm or the 1.4k ohm or does it not matter. Second how should I wire up this relay to isolate from the circuit. Thanks.

How do i know which resistor to use for this vehicle? What should the voltage be once I test it. Also I thought for isolating the circuit you needed to use 87a on the relay.

That however is a very nice diagram. Where did you get that from.

yea i got that form bulldog, i though DEI had one and i though code did to. when all eles fails i look up bulldog crap, but the diagrams do coem in handy, to lazy write them out :) plus when peole see a dirgram it easier for them.

It did make it  a little easier. The parking lights rests at 4.7v and go to 2.5v when energized. So which resistor should I use.

try 330 ohms. The higher value will trigger the headlights.

allright thanks guys for the quick response. Can I get one more member to confirm that the diagram that swamprat supplied is correct. I'm not saying your wrong, i actually really appriciate it  just better safe than sorry.

Its correct use the 330 ohm resistor and you'll be stillen'
