    i have a Nelson harness too & didn't have to hook anything up to the brakes, & i don't have a neutral safety switch, & mine shifts & stops just fine.
    how's your idle when you try to stop, is it high?

    My idle is just fine. Warm and cold. I dont have a accurate reading bc My tach is way off and I need to call Nelson to see if they can fix it/ recalibrate it with me sending my ecm back in. But I do know its idleing about right. Sounds like its between 600 and 1000. When I try to stop it might rev up a tad because it wants to leep forward but then ends up stalling if you dont put it in neutral.

    More pics and another question

    Does anyone know what this connector is for?!?? It is braided and shielded (has a protective caseing around it) And then it also has a black wire with a white stripe. What Im trying to figure out is where that black wire with the white stripe goes. I want to say its a ground but I am not rreally sure. The 2 wires coming out of that connector is purple w/ white stripe, and green with black stripe.

    the first pic is an exhuast bung for my air fuel ratio gauge.
