Ford B&O Key500 Harnesses

I purchased this harness and the infinite baffle block off plate together for my 2025 F350. Both were super high quality and saved me the time of figuring out what connectors I need and what wires needed spliced to get the feed to my kicker key500.1 amp.

I had a couple other questions and when I called the SGS guys they were super friendly, helpful and knowledgeable on the phone.

Worth every penny. Got me up and running in no time. I paired this with a pair of Rockford shallow 8's behind the seat and the performance is incomparable vs the factory "subwoofer".

Will absolutely go straight to SGS for any future needs.

The harness is exactly what was needed to tap into factory signal for after market amp. Only problem I ran into is my new amp is mounted 2-3 feet away from the factory amp and this harness is pretty short, so I had to go searching on amazon for the 4-pin extensions, which I could only find in 8" segments (made of computer uses). Definitely would be nice if SGS sold some extensions that could be purchased along with the harness so buyers could be sure they're getting the right products and they're all arriving together. But that said, their harness makes life easy, and shipping was fast! Plug and (wait for extensions and...) play! ;)

Harness is perfect!!!!! Made install with factory equipment a breeze!!!!! Recommend to anyone adding a sub to factory set up!!!!! These guys know what's up!!!!!
