Electric Pump Wiring Harness With Sealed Fuse & Relay For Bosch PCE Brushless Circulation Pumps

This harness is designed to operate the Bosch PCE brushless fluid circulation pump when adding a supercharger and turbocharger with a liquid to air intercooler to your vehicle. Heavy duty construction includes an OEM style sealed relay and relay holder and a sealed fuse holder and properly sized wire to minimize voltage drop and maximize pump performance and durability. High quality automotive grade TXL wire used for added durability.

PSS Part #: PSS-PCE-1002

Wiring details:

• Wire lengths:
  • Pump connector to relay length = 36"
  • Overall power side wire length from ring terminal to relay = 24"
    • Relay to fuse 12"
    • Fuse to power ring terminal 12"
• Ground wire ring terminal to relay = 24"
• Pump relay activation wire length = 36"
• Wire size
  • Fused power wires = 12 AWG TXL
  • Ground wire = 16 AWG TXL
  • Relay power and ground to pump connector wires = 16 AWG TXL
  • Relay pump activation wire = 18 AWG TXL
• Fuse = 15A

Note - wired for simple on-off control (fixed speed). The speed control pin is empty so the pump will run at full speed after a short start up delay. If you want to run variable speed control you can run the PWM speed control signal to the additional pin location (not required). Most OEM intercooler systems run the pump at full speed under all operating conditions.

Compatible with the following Bosch PCE pump part numbers:

• 0 392 024 058  (12V pump)
• 0 392 024 078  (12V pump)

May also be compatible with other pumps and devices that use a 3 pin TE Connectivity MCON 1.2 connector.
