Hi guys.

For the past month ive been trying to find vacume leaks on my 86 2.8 that might have been causing my backfiring prob. Only to find out that the wire i thought was the est plug was ...not. Ive been in several junk yards i have seen several of these est plugs however when i return home mine is not present if i had a camera id show that none of the wire looms on the passenger side are safe from my searching but still no est plug to be found... i was going to just cut the god damned wire and install a quick disconect but i also can find no tan wire with a stripe in it to save my life. I have come so close to taking my jack bar to the windsheild of this thing its not even funny. So i come to you to ask which wire from the distributer is it so i can trace it back a little and chop the damn thing any help on the subject would ever so greatly appreciated

 

The tan one with the black stripe, found in the 4-wire connector on the module...
