Yes it does. It is on the left side of the TBI housing. That is the thing that looks like a carburetor, it will have a electricial connector hooked to it. It is not the long piece that comes out of the left top side of the TBI with a wire hooked to it. It will be on the SIDE of it towards the bottom, It's not a big part. It will have 2 small screews that hold it on.
