Rywire Mazda RX7 FD3S 13B Mil-Spec Engine Harness w/Denso Primary & Secondary Plugs - RY-13B-MILSPEC

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)

Linked is the pinout for this engine harness: chassis customers must send in the large BLUE connector near the computer plugs off of their engine harness for us to install.
