Our original wiring simply deleted the OEM 86 fuel pump ECU. While that works fine, it does keep the fuel pump running when the ignition is on but the engine is off. With this relay, the fuel pump primes for five seconds and then shuts off, just like stock. 

See our most recent KPower 86 instructions for installation details. 

Notes:

• This relay is for use only with our 86 Haltech Electronics Package
• If your car has an early V1 or V2 ECU board, this relay is not compatible out of the box. You'll need to upgrade to a V3 board. To check your board version, remove it from the ECU case—if it isn't marked V3, a replacement is required. Please contact us to arrange an upgrade.
• As of November 2022, all 86 Fuel Kits ship with this fuel pump relay kit. If you have an older kit, this is an easy addition.
