Hi guys,

I just got a new F150 KR with 3.5L EcoBoost and need a little help.

Am going to tow this behind my bus and need to tap wiring into the rear tail lights. Does anyone know the color of rear turn signal wires and colors of brake light wires?

Also, Is there a tuner that I can get some more HP? Looking for 50 HP or so, without hurting the engine.

Any help is appreciated.

 

Welcome to the forum.

 

I have no clue about your tail light wiring question. However, I do have an answer to your other query. Ford offers performance tunes for the EcoBoost trucks. There is a separate physical tuner, and then the tune itself. You can find the package here.

 

I would not tap into your rear brake lights. Almost everything runs on a canbus system, and most likely it will cause issues with many other seemingly unassociated modules, meaning you will start getting messages for many faults. I would consult someone knowledgeable, camper dealer, etc. These new vehicles are not like days of old when you could tap into almost anything without issues. They are very sensitive to even the smallest additional current draw, and it confuses the heck out of them.

Thanks for the info on the Ford Tuner, no tune later then 2023 (sad)
