Honda Pioneer 1000 DIY Fan Override T-Harness. 

This T-Harness gives you the ability to rig up your own fan control switch. Wire it to come on upon demand, turn off upon demand, or keep factory auto mode. No need to splice your factory wires. Just unplug the factory fan harness and plug in this T-Harness to gain access to fan control. No cutting of the OEM harness is required. 

You must provide your own switch and power management system. Fues and relays. 

Choose year:

  • PIONEER 1000-3/5, (2016-2021). 
  • PIONEER 1000-3/5/6, (2022-23)

* WILL NOT WORK with the Pioneer 700, Pioneer 500 or Talon models.

Wire Identification: 

  • Red wire leads to the fan. Apply 12v and the fan will come on.
  • The blue wire is incoming from the factory auto-fan relay. 

2 ways to wire it up. 

On, Auto - Combine both the blue and red together to create a Fan Override keeping factory auto mode. Use an On/off switch or relay to send 12v to the fan. 

On, Off, On Auto - Wire the red and blue separately using an on/off/on switch to have 3 choices. The red wire should be the output. The blue wire is the factory supply input. And you need a 12v supply line. 

Note: Factory fan operation recommends the use of a relay with no less than 15A fuse. But most quality rocker switches are capable of handling this load.
