Hi I need some good help out their. I would like to run my headlights instead of my parking lights. I have a parking light output that has a relay in the module. I was told I need to add a bigger relay to support the headlight amp something like 30/40 bosch relay. The problem is I dont know how to hook up the relay. I have a 99 ford taurus se there's to red wires at the headlight switch both (+). Can anyone help me!! thanks!

Do you mean you want them to blink when you arm and disarm, or you want the lights to turn on when the car is remotely started?

Well, I show that the headlight wire is a RED / yellow (+) wire, like you said. I guess if you need to add another relay, even though there's one in the unit, you can wire it like this (assuming the parking light output of the module is +):

Pin 85 = Connect to (+) parking light output of module
Pin 86 = Connect to ground
Pin 30 = Connect to 12volts(+)
Pin 87 = Connect to headlight wire
Pin 87a = Not used

Hope that helps.

yes,I want them to blink when arm and disarm and also when triggered. I tried it before but I burn out the internal parking light relay. So I heard that to accomplish this I would need to increase the amp and use an external relay and yes their both (+) thanks! let me know if the relay wiring you gave me is correct I'll try it tommorow and see if it works.

Yea, as far as I know then, that should be correct. I would put an inline fuse on the power wire, just in case. I guess you could try it to see if it works, and then fuse it if you keep it that way.

Since you said you burned out the internal parking light relay, does the parking light output still work?

I'm wondering, though, if you would have any adverse effects from this. I'm wondering if you just turn on your parking lights, if that would automatically turn on your headlights, too, because of this relay configuration. I'm almost positive that's the correct configuration, so I guess you can try and see what happens posted_image
