The truck got a brand new harness installed, how ever the truck wont accelerate when you press the gas. The brake lights seem to be stuck on, my key wont release when you turn it all the way back.

I've tried a new gas pedal, that didnt work. Its not throwing any codes, and a mechanic said the the throttle body was fine.

Anyone able to help?

Take that bolonie somewhere else. You are full of it.

LOL. OP, you need to give more detailed sentences if you want help on the internet. Nobody here can see your vehicle. What brake light do you mean? What harness was replaced? What situations are causing these weird issues like not releasing your key? Etc.

Sounds like you have a bad shifter switch, perhaps, and/or brake switch. But, that's based on basically no info in your post.
