okay, so I know that L-jet uses the point pulses to fire injectors...my main relay is working, so what connections do i need at the coil?
i already have the tach wire, the point wire at the neg and nothing at the positive.... but i have a brown wire and two black wires joined to one both sets of wires having 12VDC on them....what gives? b |
