Mil-spec Tucked 13B Harness

This is a factory replacement style, wire-tuck Mil-spec engine harness using high quality tefzel wire and DR-25 loom. Factory layout for the FD3S, but slimmed down of the un-necessary twin turbo sensros.

This is made for a 13b engine, in a Left hand drive RX7 FD3 chassis. Intended for single turbo application only. AUTO Chassis have different engine harness connections.

The harness has connections for:

• Coolant Temp (for the computer)
• Knock Sensor
• Injectors 1-4 -2 leading, 2 trailing
• Ground for the computer
• Oxygen Sensor - Single wire narrow band
• Coolant sender for gauge
• Throttle Position Sensor (TPS)
• Intake Air Temp (IAT)
• 4 transmission connections
• Fan Switch
• Cam & Crank sensors - Trigger 1 and Trigger 2 for the computer sync.
• Oil metering pump
• Boost solenoid
• 2 computer plugs & 2 chassis plugs
• Idle motor (IAC)

This wire harness is made specificly for a RX7 FD3 Chassis, not intended to be used for a 13b standalone engine harness.

For "Right hand drive" customers, the computer type will be for the earlier model
(Our harness does not support the Austrailian 16-bit computer's from 96-98)

*Auto chassis customers must send in the large BLUE connector near the computer plugs off of their engine harness for us to install.

Below are some examples of how the fuel injector connectors will look. Please select the type that match your injectors.
