I have a 1999 f250 psd 6spd4x4 the wiring harness is shot on it I bought a wiring harness that was suppose to be right but the harness says it is for a 2000 f350 auto 2wd I was just wondering if it would work

 

I got both the under the hood harness and the cab harness also the fuse boxes

 

Are you talking about the engine harness or truck harness? Early '99 or late '99? I think that the L99 has an AIH and I know that the E99 does not.

And here's a BTT for you.

 

The truck harness I'm thinking it's a L99

 

I can't tell you for certain but The engine harness should be the same. Can you find part numbers on in? As far as the cab harness goes I don't have any idea but again, is the parts tag still on it? It might still be there.

 

I got it all in today all the plugs were the same.but now the truck won't start with the key it will at the seliond and the instrument cluster none of the gauges work I'm gonna check fuses tomorrow
