on my 87 GT, it was directly above the computer probably about 5 or 6 inches. Might be easier to take out the dash speaker on the passanger side and reach down to it like that.
6" up the wire harness or from computer in mounted position. Reason i ask Is because I pulled the computer and followed the harness 12-14 inches with my hand. Also is it bolted to somthing or free?
It is up there, it is secured in place by a plastic tree type fastener like the one used to hold the trim panel on. Removing the passenger side dash speaker helps to see it.
