Rear E-Locker

[ChevyHighPerformance]

Wow, strong opinions either way - I don't know what the right answer is, but I will add it is very difficult to design a traction system for all surfaces.

The TC switch shuts off both the stability and traction systems.

There are two wires going to the e-locker: light green and black (I think these are the colors). +battery is switched to the light green wire and the black wire returns to the transfer case shift control module where it connects to ground through a resistor/current limiter. The final circuit will be pretty simple but you need to do serveral tests first to understand what is inside the control module.

For example, you'll need a diode to clamp the inductive current for the e-locker coil to prevent an insulation breakdown when you interrupt coil current.

TC Switch?

[ChevyHighPerformance]

Sorry, I wasn't clear - Traction Control System - TCS switch.

[HummBebe]

On which model H2 or H3?

If H3, what switch are you referring to?

[ChevyHighPerformance]

I was refering to the H3. This is the rightmost switch - picture of a car with squiggly lines underneath it. Hold it in for 5 sec and this will disable the traction control and the stability system (if you have it).

That is the stabilitrac switch. Different system than the traction control.

You cannot turn off the traction control

You are incorrect sir/maam ()... there is a switch on the column... the ignition switch! That will turn off the traction control. But I don't think it's useful over 5 mpg (I could be wrong )!
