In this video I have a look at a customers GMC Yukon Denali with the big 6.2 that was towed in for a no start not crank. I have seen this enough times it's just as easy to take a guess rather than busting out the tools. Not to mention we already did a video on one of these.
Enjoy!

UPDATE: Customer had me bypass the connector and throw away the module and the battery light went out after tightening up the positive terminal. I just had it resting on there when I went out in the lot to bring it in. Now he can go get a sticker on it and get it on the road
