Hey guys going to do a 4wd conversion in the spring I have a whole donor truck just got the trans looked over all electronics redone pump run kit in the tcase and beefed up a little. Have the 4wd buttons and tccm just wondering if the plugs for the buttons are tied up somewhere since it's all connected to the main harness for the dash, I got a harness from an 03 but it was cut off the main dash harness so I'm not sure where everything goes can anybody help?
