    Grounding Question

    I'm building a new engine harness and I noticed that there are several grounds that run through it from almos every connector. Should
    I run a big fat ground on the engine harness and connect it to the block or the transmission so I can have a common grounding point?
    The Ecu has injector ground, input ground, output ground and cpu ground.
    At the schematics all of them are grounded through different courses to the block. I suppose I can do what I want right?

    Generally you want to have a common return ground for all sensors running back to the ECU and then the ECU grounded with some big wires to both the engine and chassis.
