    Pic request: Mounted DBW throttle in an 88-98

    I started working on my interior wiring today and found that its not going to be possible to mount my pedal directly to the firewall. Does anyone have pics of how one could be mounted? also the pedal I have seems to have very little range of motion. Is that normal? Thanks

    I was going to go this route. I had the harness and the only thing I didnt have was the pedal and the box for the DBW.

    Found it easier to get a standalone harness and go Cable operated, but I bet you got all that with the engine you bought.

    Good luck!

    I already have everything for DBW, I wanted to go cable but it didn't work out that way.

    Trust me, go cable. DBW is a pain and you can't even manually rev the motor. you have to press the gas pedal. and the pedal looks like poop in our trucks

    Yeah but like I said I already have everything and don't really want to have to hunt down another reworked harness, tuned PCM, throttle body and all of the cables and brackets needed for DBC. Unless someone sees this and wants to buy all my DBW parts? I'm sure someone has done a DBW swap that could post some pics.

    i built a bracket to mount the pedal to the firewall, and then cut the new pedal off of the assy and welded the stock pedal to it, worked great untill the truck was stolen.

    Thats probably what I'll end up doing. Sorry to hear about your truck.

    I actually like my DBW.
    My swap isn't in a 88-98 truck, but I still had to modify for the DBW. I was able to get the top bolt of the pedal assembly to line up with the top hole on my floor/firewall so that was good. But the pedal length was a little long so I ended up cutting it off, and fiddling around with a set of vice grips holding the two ends together until I got it where I wanted, then welded it up. Doesn't look there's much welding done in this pic, but the other side has more weld so it's all good. It was one of those, "It's 1:30am, I can get this done before 2." kind of things haha.
    Here's the pic:



    Oh, and with my pedal out of the car, I thought that it didn't have much travel at all either, but there is more than you think once it's mounted and you're using your foot haha.
    There's no replacement for displacement.
