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.
