PLEASE READ!

Chrysler uses Canbus for the headlight system. HID conversion kits are well known for their flicker/strobe and Lampout light problems when used on Canbus equip'd vehicles. These problems vary from one manufacturer to the next.

There are ways to eliminate both of these cases.

They include:
1.) Relay harness (most sellers can provide these with their kits only if you ask). The relay harnesses will eliminate the strobing effect in most cases. I suggest everyone use a relay harness with resistors.

2.) Resistors (Quality 50w..6ohm can be purchased online for pretty cheap.HERE.). These turn off the Lamp out illumination bulb for guys using a relay harness, and store no codes of High Resistance in the computer(06+ guys) which may cause to the circuit to be disabled after a while(no lights at all). Resistors are used on EACH lowbeam wire and EACH Highbeam wire because the driverside and passengerside are on independent circuits(for safety reasons) You need a total of FOUR resistors to get the job done. Resistors get hooked to power feed on one end and get ground on the other.

3.) Capacitors aka Cancellors. These are premade plug-in units that eliminate the flicker/strobing for plug'n'play applications(No relay harness used). I advise against not using the set-up of Plug'n'Pay and cancellor kits due to the massive spike in electrical current on start-up(Inrush current). Capacitors charge up very fast and will draw more current than your switch and circuit is capable of supplying. This rush of charge is actually what tricks the pcm into thinking there is a good bulb drawing current on the other end. This problem will likely be prevelant overtime as it will begin to wear down the contacts of switches and any contact point.

*Fogs are not canbus on any Ram 2008-older.
*You still should use a relay harness with the fogs even though they don't flicker/strobe when installing a pure Plug'n'Play kit. HID technology draws signiciant amount of current upon start up to heat up the bulb. The Inrush current can be up over 15A on some of these kits and cause popped fuses or circuits to be electronically shut down by the tipm. Just because HID lights use Less power(35w) and draw less current at operating temperatures, doesn't mean they are safe for the electrical system which isn't designed for it. The High inrush spikes slowly wear down electrical contact points. This includes the headlight switch, the Instrument cluster, the fuse panl or 06-08+ TIPM($$) module. Put the HID's that shouldn't be directly plugged in along with the capacitors that draw lots of current and you could have one big mess on your hands creating electrical trouble. I'm just sayin.... They'll directly plug in and work like a charm, but for how long? I'd say it depends on the kit and how many times you turn the lights on/off?
Using a Relay harness avoids any hard strains on any of the factory components. Everything functions as it should and componenets will last much longer.


Make this list of items to get:
4-50w 6ohm Resistors (they're all over Ebay)
1-Relay harness (Make sure this comes with your kit)


All Dodge Ram 2002+ have canbus system for their Headlights, therefore, the headlight circuit will need to be corrected. All Dodge Rams 2002-2008 DO NOT have canbus for the foglights.
