BEAMS AE86 Swap wire harness kit

BEAMS AE86 wire harness with ECU

Availability: In stock




  If you're doing a BEAMS swap in your AE86, the wiring will be a big question to answer. This all new wire harness and ECU kit for the BEAMS is the only plug and play solution and sets the benchmark for quality and value, adding one of these to your build will make the instalation go a lot easier!!   

General Fitment

   The harness is designed to fit nice and clean on the motor and fit under the factory valve cover plate. The overall length is designed to route the ECU inside the cab on the right hand side of the car, typical to LHD chassis. The length of the plugs are configured to be as clean as possible without extra wire making unsightly loops.

    You willl need to install our BEAMS throttle lock (T-TL-S1) to convert the throttle body away from drive by wire. You can also replace the throttle body to a cable only type or convert to ITB's.  

    This AE86 specific harness is designed to plug directly into the AE86 body plug and run off the original key as well as run the stock gauges. The tach will require a resistor mod (included) or a tach adapter (not included). There is also a wire provided to tap into the factory relay to power up the fuel pump. 

GT-S or SR-5 Windshield wipers

   If you have an SR-5, the wipers are a seperate harness from the engine and you don't need to do anytihng. If you have a GT-S, the wiper wiring is routed through the factory engine harness. When you do a motor swap, you need to reroute the wiper wiring if you want wipers. We offer a GT-S wiper harness kit for motor swaps, it's needed with the BEAMS, part number L-PW-AE86-GTS-W

Set up and Expansion

    Right out of the box the harness and ECU will run full sequential injection and sequential ignition as well as the dual VVT. The Monsoon ECU also has an onboard MAP sensor, so elimintaing the MAF won't require additional wiring and adding of a new sensor.

   As a standard, we load the ECU with a start up map for running the stock intake. We can also load an ITB map if you'd like to go that route or upgrade in the future. All start up maps come with a 3000 RPM rev limit that allows you to run car right away. We recommend all motors to be tuned if you choose to raise the rev limit, due to differences in all instalations, our tune is not set up to run all motors.

   If you plan to go ITB's, the harness has a stand alone intake air temp sensor for the elimination of the MAF and the on board MAP can be used for smoother idle tuning.

   If you want to go boosted, the on board MAP sensor is ideal and the auxialry 2 wire or 3 wire plug can be used for boost control.

   Want Nitrous? The auxialry 2 wire or 3 wire plug can run nitrous solenoids and fuel pressure sensor mapping as well.

  Harness Manufacturer

     The harness is made in the USA by Panic wire at their facility. Panic wire has been in the wire harness business for over 12 years and making BEAMS specific harness's for 6 years. The concept behind this harness and ECU package is to deliver an affordable and effective  package with a bit of room for expansion and simplicity in installation in a mutitude of BEAMS swap applications.
