SuperDuty Upfitter Wiring Harness

More stock due by the end of April 2025

Version 2 of this harness is now up for order!

Revision changes:

• extended the ground leads by 6"
• increase wire lengths on the connector side of the harness by 2" so that connectors have the ability to spread out a little more.
• removed the PTO/B+ connections
• added a butt connector to the ends of the positive legs for the harness and both legs of the pigtails(no more solder shrinks) 
• Caps are also now included along with heatshrink to cover the butt connections

Turn the short, poorly placed, hard to get to factory upfitter wires into easy to access, plug n' play connections to easily add accessory lighting and other electrical accessories to your factory upfitter switches. 

This harness takes your 6 factory upfitter wires and converts them to 6 x 2 pin(power and ground) waterproof connectors. Adding auxiliary lighting couldn't be any easier. 

All connections are labeled with switch # and Current Rating for that switch. 

Only Tools Needed:

Wire strippers to strip the factory wiring

Heatgun/Hair dryer or lighter to shrink shrink tubing

Wrench to add ground lines to battery negative terminal

Also included are 6 x 2 pin female connectors with pigtails to splice to any accessories that don't come with this type of connector so that hook up is easy and fast. 

Note: harness received will have braided wire loom, not the corrugated that is shown.
