Hey I purchased a raptor HID kit 35w HI and LO beam from DDM tuning.. And i purchased the HID 35w fog light kit from DDM tuning. As soon as i installed them my hi/lo beams work great as long as my fog lights are not on. But as soon as I turn my fog lights on with my headlights my headlights start to act crazy. For example when my fog light switch is on inside the truck and i switch my lights to high beam the passenger headlight stays on hi beam and the driver side will switch back and forth from lo to hi when i hit the switch. And sometimes both of my headlights will stay on hi beam when the switch is on low beam. As soon as i turn my fog light switch off inside the truck my headlights work fine on lo and hi beam. There is only one relay and fuse for the headlights and fog lights. Do i need to have a second relay for just my fog lights? Or do i have a short somewhere? If anyone has any suggestions let me know please

Make sure you have a solid ground on your hi/low beam. On mine I brought the negative back to the battery for both. If not that could be a bad relay. Ddm is pretty good about that and should send you a new relay.

Had the same problem, ended up putting in two relay harnesses got the from e bay 25 for both kits has two 30 fuses in each the factory harness cannot handle the power up

Thanks I will give that a try. Now once I have my fog light switch on my hi beams stay on when I turn the switch back to lo beam.

I tried running both the ground wires to the negative side of the battery and that did not fix anything.

What kind of relay harrness did you buy? And did you hook it up the same way you hooked up your headlight relay?

A hid relay kit that I found on eBay nothing special just make sure it is fused with two fuses for when they first turn on as for the fog lights I cut into my marker lights so they stay on for hi and low.

I already have one relay and fuse for my headlight HIDs. My fog lights are wired up to my stock plug. So I need a second relay and fuse for just my fog lights? Also I found an error free load resister for my fog lights that I could use.

I just did the Bambi mod and it fixed my issues.
