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.

  • 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 a On/off switch to send 12v to the fan. In this mode without the use of a relay, the swirch may illuminate anytime the fan is on from auto mode. 

On, Off, On Auto - Wire the red and blue seperterly using a on/off/on switch to have 3 choices. The red wire should be the demand lead. The blue wire is a supply. A 12v line will need to be a supply also. 

Note: Factory fan operation recomends the use of a relay with no less then 15A fuse.
