All online orders are for our default harness length. Our default harness length is approximately 42" from the passenger side rear head and mounts the modules under-the-dash. If you need a custom layout to mount the computer elsewhere, call to order.

Tap shifting Option:
If you add our 10L floor shifter with integrated tap shift we can't use a truck tune. This means further tuning maybe needed by your own tuner of choice to get dialed in.
