So then why does my 88 hf have the blue plug too?
Also i looked into what that blue plug plugs into and and it has a wire coming from it that plugs into a light that is for the up-shift light so i don't know what thats about. If u asked me i would say that blue plug is just for the upshift fuel economy thing but i don't know.. And the wires in my dash include the blue plug so i don't know.



if that don't work try pasting this """http://community.webshots.com/storage/1/v4/9/85/22/54498522RGkDzo_ph.jpg"""
