Thanks all. Glad I joined the forum. I am working on getting some pictures put together of the final product. The Yukon has been in the family since 2011. It has survived many adventures and one teenager so far. The next one is about ready to drive. Hence the paint job to spiff it up a bit. Next on the list is getting it lifted, then the interior.

Thanks! Got any pictures? We should post a thread with all the GMT 800 sensors like that and sticky it.
