Rywire Mil-spec Adaptronic 13/20B Harness


The 13B and 20B are most widely produced engines. They were the basis for all future Mazda Wankel engines, and was produced for over 30 years. These harnesses are warrantied and guaranteed to work, we provide excellent installation phone support and troubleshooting to ensure this reputation for quality, however they are non-refundable.

This is a wire-tuck style Mil-spec engine harness using high quality tefzel wire and DR-25 sleeving.

This is made for a 13B or 20B engine with a s6 adaptronic modular ecu.  

 

Please note that if using this on a 20B engine, you will have to add 2 more ignition output wires, as this harness is only setup for 4 coils. It is already setup for 6 injectors. 

 

Ev14 selection are for id725, id1050x, id1300x, and id1700x. Id2000 use denso connectors. 

The harness has connections for:

  • OEM Coolant Temp (for ECU) Adaptronic
  • OEM Idle Air Control Valve
  • Knock Sensor - Bosch style
  • Injectors 1-4+2 (6 total)
  • 2 Grounds (one per rotor)
  • OEM Coolant for gauges
  • OEM Throttle Position Sensor (TPS)
  • Intake Air Temp (IAT -Bosch style)
  • 4 transmission connections
  • Fan Switch
  • OEM Cam Angle Sensors (2 total)
  • OEM Oil monitoring pump
  • Boost solenoid - EFR Series style
  • Adaptronic Modular EMS plugs with Canbus Deutsch connector ( 2 pin connector)
  • Oil Pressure - Delphi style
  • Fuel Pressure - Delphi Style
  • Flex Fuel Sensor- GM style
  • OEM Fuel temperature
  • Deutsch Ignition Auxiliary connector  (ign1a) plug-and-play sub-harness

 

This harness does require 5 wires to be connected to the OEM dash harness as seen below( ecu power, fuel pump, VSS, Tach, and clutch switch). These are the the loose wires that come off the 20 pin large gray connector( which also has the 2 white connectors).
