relay blocking or use of a diode?

So I have a 03 dodge.  There is a 4.5v rest resistance on the parking light circuit.  I put a 1.4k resistor on it, but i am getting feedback and it is not only clicking on my parking lights when I click lock or unlock, but it is also switching on my headlamps.  help?

BTW it is a -200ma trigger to -parking lights

u would use a relay and a diode. If your parking light output is only 200mA, i suggest you use a relay. But im sure compustar have built in relays for parking lights.

if you dont have an onboard relay from the compustar, connect up a relay like so.

85 - constant 12v

that way, when you dont use your remote start, the fucnition of the factory lights can be used accross the relay. Once the relay is active (from lock or unlock), the relay is triggered to send 1.4k ohms to your parking light wire.

parking lights are high current drawing devices and can load out the coil. Well use any diode that you have.

any of these will work just fine

1N4002

rectifing diodes. you can use any of those, but if u would like to play it safe, go with the 1N4004. that is what i use most on my installs for isolating circuits.

The diode wouldn't be necessary here.  Any device that is designed to drive a relay (ie 200mA output, ) will have the diode integrated with the drive circuit.
