Important notes on OBD0 and OBD1 fuel injection differences

• You may use low impedence type fuel injectors with an OBD1

ECU but you MUST use a factory resistor box.

• MPFI models have a resistor box in place from the factory.

• DPFI models DO NOT have a resistor box from the factory.

• If you are using high impedence fuel injectors, REMOVE the

resistor box from your vehicle.

How to remove a resistor box from your MPFI vehicle

• Unclip the resistor box connector.

• Unbolt and remove the resistor box from your vehicle.

• Cut the resistor box connector off of the engine harness.

• Splice together ALL the cut wires that were going into the

connector. We recommend soldering the wires together. Use

electrical tape or heat-shrink tubing to insulate the connection.
