I dont get it your saying take off the solder 1-9 and solder the 7 back together can you show the complete piece how you have it.

Ok stock comes soldered from the factory 3,4,5 and 7. Pay attention to what i circle and say in the pictures. NOt the actual picture its just for reference.

Heres a list i put together

This is what i got from my testing, the resistor on j2 needs to be placed no matter what. These are the switches that need to be open or closed.

18s with j30 rear gear
switch 7 soldered
all others open

18s with stock 4.08 rear
switch 7 , and 5 soldered
all others open

17s ie 245/255 35-40 sidewall with stock 4.08 rear
swtich 6, 7 soldered
all others open

stock 4.08 rear with stock wheels and tires 205/55/16
switch 6,7 soldered
all others open

These settings should be pretty spot on, at worst 1-2 mph off. You can fine tune it adding more or less percentage but that should pretty much get you where you need to be.
