Hi, Can anybody get the wiring scimatic for a 2010 silverado
tow/haul switch, from PCM to gear shift lever ? need help badly.
Please send to turboal@aol.com. thanks in advance.

 

good luck thats the same thing im looking for. its a white an black wire outta the steering, dunno after that

 

What are you guys trying to do?

 

I want to help you guys out so I'm just gonna post up what I was able to find. This isn't my area of expertice so I'm not sure it's going to help but you can't say I not trying.

 

I am trying to make my 6spd manual mode work without having the BCM reflashed. if not possible, then ill just have my BCM reflashed with the 6L80e option. i guess you can say i need the TCM wiring harness and the manual switch button wiring diagram. on the shifter, its only 4 wires. 2 white and 2 black. 1 set is to the tow/haul and the others are the up/down of the manual shifter
