  • ECM Location and wiring...

    I can't believe so many people here are almost done with their systems including me. Wooo Hooo!

    I opted for the Do It Yourself kit that Affordable Fuel Injection offers.

    I thought I would start a fresh thread for the ECM and wiring.
    Here's a picture of the hole I cut in the firewall for the harness. It comes out behind the glove box. From the inside it was just wide open, push a couple wires out of the way. Once I got the hole cut I went back with the hole saw nice and slow and made a nice hole in the insulation as well.
    I chose two inch because everything would fit through it and I had a two inch grommet that will fit the hole. (from NAPA)
    Once the grommet is in you cut an X run wires and seal with silacone.


    I'm also going to sacrifice my glove-box for a control center. With a center console it's no big deal.
    The big hole will run all the wires into the glove-box and the holes on the top should keep it plenty cool.
    Besides the ECM inside I'm going to keep the fuses, fuel pump relay and aldl port in there as well.
