i bought a e-locker with switch and ecu wires cut. as far as wiring goes it looks like u can ground 2 of them for the 5mph and something else. my question is do u just wire it up and send 12 volts and a ground to it. i would like to test the operation before installing, all the youtube stuff is kinda vague. schematics are good just wondering if someone could simplify for a newb.
