I used it on a 1985 stang the only thing I noticed different (from 86-93) is the fuel pump relay is with the wot cut out relay right under the maf. chris
for 225.00 or whatever the current price is you get the "main harness" which is the harness off the computer straight down the r/h side of the eng compt to the maf and 02 sensors. across the aft engine firewall (not included engine harness)around the master cylinder and down the l/h side to the coil and solonoid. it does not come with any thing else except some fuel pump stuff. chris
