Dunc

Thanks again. I'm going to check with some local dealers, maybe I'll get lucky and will find a damaged housing that I can buy to do some testing on first.

Thanks! This should be pretty close, it might actually fit with the stock dust caps. Time to break out the credit card and start buying components

Does anyone currently have a stock projector laying around they can measure for me? I am curious what the measurement is from the mounting points on the stock projector to the rear (without the bulb in it.) I'm trying to get a more exact idea of just how close/far my personal setup will be from using the stock dust cap. That way I can compare this measurement to the projectors/connectors I'm going to use so I'm more prepared before I open up the housing. Attached is an example to show the measurement that I am looking for. Thanks! EDIT: And now that I think about it, an overall length would be nice to have as well.

Thanks. I sort of looks like it is using a D1S bulb type. If that's the case then I'm definitely going to ignore that setup all together. Thanks!

Do you have a part number you used to find the ballasts? I'm curious as to which one they are using.

Has anyone seen the '15 Yukon ballasts? I was at the dealer today checking on other items and seeing a Yukon with HIDs peaked my interest. I'm curious about the wiring harness and ballasts. Perhaps it is something that could easier be converted to the Sierra? I'm guessing not, but it just made me wonder.

Is this possible if there is the linex spray in liner already installed from the factory? I haven't looked yet, but I would think the linex is sprayed over the bolts and I wouldn't be able to remove that tailgate panel. EDIT: Nevermind, the factory doesn't go over the bolts.

Yep, everything functions normally once I put the key in and start driving.

It's only 39 here currently. I double checked and the HVAC heat comes on, but the heated seats definitely are not warming up even though I have the setting turned on.

I've noticed the same thing and we have the same vehicle. Would love to know what defines warm/cold. The heat comes right now, but I'm thinking that the seats are not coming on as well.
