New to the forum. I have visited this site many times but never registered. Being a newbie not sure if this is where I should start. I live in Roseburg Oregon and have a 2006 Silverado 2500 HD 6.6 Duramax LBZ. Love to fish for halibut and tuna off the Oregon coast. I have a 8,000 lb boat that I tow behind my truck regularly. This truck is a pulling machine. Anyhow the truck, now at 168,000 miles had a meltdown. Burnt the transfer case controller and some wires. Needless to say I have been working on the wiring the last couple of days and have the wire repaired. Now to put the new tccm in and power up. Not sure what all I should check before I hook up the batteries. Any help would be great!
