ground wires, fuel pump harness and ignition harness ground black leads to the same

point using clean & paint-free bell housing bolt connection. Alternatively, you may

connect the system grounds to the same point on the engine as the battery negative

lead. Insure that the engine/transmission is grounded to the chassis and body as well.

See Figure 20 for system Grounding at bell housing. Note Negative battery cable and

paint removed from bell housing under terminal contact area.

If space is confined, an alternative method is to run system power to a firewall mounted

insulated hot-stud and a single 6/8 gauge wire to the starter solenoid.

Connect ignition key-switch lead to the operator ignition switch. The switch should

be capable of maintaining uninterrupted +12V power to the system in the “On”

position, “Crank” position, as well as the transition between the two. Many older

vehicles (pre 1974) have ignition switches that bypass power from a ballast

resistor during crank and these systems typically have a momentary “dropout”

between the Run and Crank positions.

These

types of ignition switches ARE NOT COMPATIBLE with your Edelbrock

Pro-Tuner system.

If you have such a switch; it must be replaced with a newer non-interruptible

version for proper operation.

•

Connect remaining wires, including fuel pump and ignition harnesses. Unused

connectors should be coiled and secured away from dirt, debris, and heat.
