I have a 05 chevy 1500 2wd. Did a swap with a 01 4l80e trans. I got the frost conversion wireing harness.

My question is: I have 2 speed sensers on the 4l80 and my 4l60 harness only has 1 plug. What do i need to do? I was told it wouldn't shift right unless they r both pluged in. I have been searching, but still don't understand what to do.

 

I dont know about the frost conversion harness but when i put my 80 in i used the stock harness and i had to run the wires from the rear VSS to the PCM and pin them.

 

With the frost harness you don't need the front iss.

 

Are you sure about that? I have been trying to get ahold or frost with no luck. I just don't want to mess up a new transmission.

 

Are you using this harness with the relay?

If so then yes I am sure.

 

That is what i have. Thanks for the help bro.
