does anyone know if a 2003 dodge truck has positive or negitive switching on the headlights? I want to put wig wags on there but need to know that.

mabey thats what im tring to ask. do you know what im tring to do?

hot is switched in any application I'v ever seen.

i am a firerfighter and want to put more lights on my truck. The module boxes they sell have two types pos and neg

check the wires coming off the headlights, if 1 of them goes into the metal, that is a ground, and no way could be switched. I would wire it, hot wire switched. I guess when you get into some older import cars, some used positive ground and therefor, the negative would be switched, but never seen it on anything american.

The 2003 Dodge trucks have a trip fire ign. system that is closed loop. I would S T R O N G L Y suggest that you contact dodge motor co. before introducing anything into the electrical system for advise.

ok thanks for the info. do you know any tricks on making your own stobe lights or alternating flasher units?

thanks to you to hambiskit. what does closed loop system mean?

most anything that workes off of the computer on the newer cars is ground sw, ac. fan motors, heater, door locks, most everything now. if i was ordering something for a new car I'd let the co. I bought it from tell me what i needed.

Closed loop firing system is the combination of circuits that must work at all times with the computer in order for the ignition to release fire to the cylnders. Interupt the wrong wiring loop and the truck won't run. I have seen this to include door opening sensors, brake safety switch's, as well as fuel pressure switch's.
Chrysler changed a lot of their systems with the introduction of the V-10, and has changed them again every 3 years or so "trying" to improve on the "bugs"
I am sure that you can get this from Dodge for your model.
Good Luck

ok i will contact the dodge dealer. the truck i have is a 3500 dully with the hemi. i will let you know what i find out just to pass on the info

Hey Thanks

I am a volunteer firefighter here in southern Indiana. I also have a Dodge Ram, but I don't have wig-wags on my truck, as I live about a block from the fire station, and don't get to run my blue lights very often. If you go to www.galls.com, they have a self-contained wig-wag set up for 19.99. We have one of these installed on our '99 Ford F350 first out truck, and it was pretty simple to do, and works fine. They also have strobe kits, or pieces to build your own set up. Hope this helps!
