Ok well I have 2001 GMC Sierra and I bought some denali projectors for it but the low beam connection from my truck does not fit the bulb that the headlights came with Im not sure what to do because I thought I heard it was direct plug and play? Can anyone please help me? Anyone who has done this modification to their truck.

Thanks

 

Mine plugged in directly. The 9005 bulb for the low beam had a small harness on it which ran to the bottom of the light where it accepted the stock 9006 bulb. Did your headlights not come with these little harnesses (they are maybe 3" long?) Are they OEM?

 

did you buy them from the dealer or somebody else. mine just plugds right in too. no problems.

 

Well I know that they are OEM because they have the orange reflector and I plugged the high beam harness on the low beam for the projector and it fit right in. Do you have any Ideas on what I should do? Or maybe the part number for the high beam wiring harness?

Thanks

 

Well actually they did not come with the harness it was just the housing and the bulbs. Man Im confused

 

Sounds like you didnt get OEM units. Where did they come from?

 

I had OEM's on my '03 GMC and they plugged right in also

 

Well I got them off ebay. Well is there anyway that I could change the low beam harness a high beam harness. Well where does that wire harness connect on the opposite end of the housing? Maybe I can try to pull it off and look for one like one on my high beam because I plugged in the high beam connector from my truck to the low beam bulb that the denali projector has and it went right in nicely. Do you all have any idea of a price for the harness.

Thanks

 

No idea on the price of the harness. It didn't really look like something that would be sold seperately either. Do you have a picture of the back of the headlights? That would help out alot...

 

Well here are some pics but Im not sure of how they came since they were taken with a cell phone. But the thing that is strange to me is the fact that you guys say that they plugged right into your harness and the low beam on mine doesn't even want to go into the bulbs that come with it I mean they are both 9005 but the harness plug for my low beam is a little bit more bigger than the one for the high beam. But what I dont understand is that all denali projectors have 9005 right so how is it different for you guys and for me if the bulbs are the same size on all trucks and cars.
