    i believe nelson charges 450 to rework your harness and 650 for a new one. or something like that.

    Since I am having nelson do my harness now, I think I am going to switch to drive by cable while I am at it since I dont have a ecm yet. So my electronic gas pedal (has been modded to fit obs truck) and the gas pedal control box (with wires) is probably going to be up for grabs. I plan on getting a DBC ecm and 96-98 vortec throttle cable to run with a LS1 DBC throttle body.

    Anyone see problems that I will run into?

    Ok Ill keep that in mind, UNTIL I get ahold of Nelson's ( They aren't answering their phones for some reason today, or returning my messages) I am going to hold on to it until I know what my plan is for the harness and DBW/DBC. Ill get some pics of my setup for ya soon. I got it setup for WOT once it hits the carpet and I have it setup with 2 bolts one of the very top and i drilled the bottom one in the firewall and put a nut on the other side

    Will the tps swap over to the dbc from the dbw? Or will you have to get new sensors as well?

    Nope, I am having my harness made for DBC from Nelson's. So I will have to get new TPS and IAC Sensors for my DBC TB

    Got a LOT done on the old harness last night. Have a few questions. What is the relay on the firewire kind of by the brake master cylinder? Is it a relay for backup lights?

    And do I use all my old t case connectors? Anyone have diagrams for the tcase?

    One last thing is how do i get my reverse lights to work? Any diagrams for that as well?
