OK I dont know where to post this. I know someone has done it but having a tough time finding it. I have a '99 psd f250 crew cab lariat, I just purchased seats from a 2005 F350 that are lariat heated and power. My seats are power but non heated is there a way to hook everything up and if so has anyone done this

 

Hopefully you got all the controllers with your new seats. Go to Autozone's site, I am sure they have all the diagrams for the 2005 seats. If I remember right, all you need is a fairly heavy circuit for the heat controllers and a smaller key-on circuit to trigger it all. You can come right off the battery with two 30 amp circuit breakers, run two 10 gauge wires from those into the cab, and supply the controller in each seat. I am going by memory on that also, but if it only takes one 30 amp circuit, you could do that also. Just copy what the diagrams have, though I would not try to tap into the existing fuse box for this(except for the key-on power), too complicated.

 

all the controllers? Like what.... I have the switches that are connected to the seats and thats it. What else do I need to grab, I can go back and get the parts from the guy I got the seats from I just need a list of what I need. Thank you

 

See that box? They call that the "heated seat module". I am not sure, but I am thinking it's mounted on or under the seat somewhere.



Here's the pass side seat. Looks like you only need one 30 amp circuit.



Here's a different diagram they have in the same section. This looks like the simpler version, I don't know what you have there, you will have to check the wire colors with the diagrams.
