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 |

B,
Have you opened the PDF of the wiring diagram I sent you? The dual relay is not that complicated. Relay 1: Feeds power to the resistor pack and to pin 10 of the ECU. The Power is supplied by th elarge red wire. The coil of the relay is energized (+12v) by the black coil wire that terminates at the dual relay. ________________________ Relay 2: Feeds power to the fuel pump (Black/red wire), and feeds power to the Aux Air Valve. The coil of this relay is energized in one of two ways: With the key in the on position (relay 1 energized); 1) The flap in the air flow meter is slightly opened closing a switch. Power is fed from the output of relay #1 through the switch in the AFM and powers the coil for relay #2. 2) The starter is bumped (yellow wire energized). This will energize the coil on relay #2. Without the ground for the dual relay, neither coil will operate as they share a common ground (according to the diagram). I sure hope this helps. |
