I wasn't aware there was a base model- is it leather?The nnbs base model one only has 2 wires like the nbs so trial and error is the same since mark already figured out the 4 wire plug lol.
I call it the base model cause I figure the +/- version is an upgrade option.
I actually have 2, one with +/- one without. But not an esky one. Either way the nnbs look and feel better than the nbs imoView attachment 186797
Edit: my wires were black , blue, pink , and purple . I hooked up the black and blue for the tow haul View attachment 186798
Also edit: it looks like the 4-wire shifter in the picture has white and black wires? Also, why do you have a separate wiring harness that looks like it goes between the shifter and the truck? I see it has white wires on one end. That's confusing since the shifters don't come with that white connector do they?
