Sorry about the missing digit but like i said it also could have been updated with later years My coverage only goes to 2010. anything newer then that i don't have so have them look for title no crank, no start, discharged or low battery. maybe something might come up.

Any idea what it costs to get this updated? My Denali is showing the same symptoms and has the rear heated seats. Battery goes dead in minutes. I've had alternator and battery tested.

GM part #25825642 positive battery cable. http://www.amazon.com/ACDelco-25825...=UTF8&qid=1345638137&sr=8-1&keywords=25825642

GM part #25876896 negative battery cable. http://www.amazon.com/ACDelco-25876...=UTF8&qid=1345638137&sr=8-2&keywords=25825642

GM part #14005061 battery hold down. local GM dealer about $5

GM part #11509853 hold down bolt. local GM dealer about $1

10 x 1.5 x 25 mm bolt and washer - Lowes

This is all that is needed plus batteries. The positive battery cable routes under the motor at the front of the oil pan near some other cables and includes clips to attach it to a plastic piece that already has holes in it for the cable clips. It then attaches to the starter on the same stud as the main battery. I attached the negative cable to the motor at a threaded hole in the head near the alternator with the bolt from Lowes.
Getting a wrench on the lug nut at the starter is the only difficult part. It is REALLY hard to see and get to due to the frame etc. You will need ramps or access to a lift.

Hate to ask a dumb question but I'm going to anyhow. When I replace the negative battery cable, do I actually get rid of the old one completely or just add this one in addition to what is already there?

No, you do not replace or get rid of the one already there. This is in addition to the one already there and goes to the second battery only.

Ok, I was under the impression that some of this could be caused by a faulty negative battery cable so I purchased a new one and was going to put it on. I currently don't have plans to do a dual battery system at this time. Think I should just return the cable?

Anyone know what this type of labor should cost? I called around to local dealerships and they all quoted me 95 for the diagnosis and then an additional 1-2 hours of labor for programming the rear heated seat module.

Anyone else have this done? If so, what did it run you?
