Day 2 - Carbot PC Install - False Start
So Day 2 is a bust. Finding a good Key 12V+ wire is nto as trivial as it was on my old GTI. I went on-line and asked the almighty google and it failed me. Rather than poking around like a blind lepper in search of hot ignition goodness, I decided to actually find a witing diagram or at least someone who knows exactly the best place in the dash to splice into. Tomorrow we head off to Houston for some humid golf nirvana so Day 2 will actually be day 5. Ok too much math. Back to Google.

I have had difficulty in this as well. The issue with new cars is that the PCM or BCM (Power or Body control module) constantly tests the draw on each circuit and if a circuit draws more than it is allowed, the PCM/BCM will kill the circuit.
On all my GM cars 2000+, I have usually found a HUGE positive wire underdash, near the column which is hot all the time, and usually in that bundle you can find a true 12v+ that is not metered by current draw.

The Yukon is similar enough to my Bravada, so I will dig into my notes and find where I hooked my XM and Val1.
My brother has a Tahoe also, he might have an idea
