Well, if you're on the other side of the pond, you'll have to try wrenchead.com or something. Just order an EEC-IV for a 1989 5.0L, and it'll work fine. At least I can tell you mine is working great!!! Oh yeah, I bought mine from a friend who got it out of the junkyard, along with the MAF sensor. Good luck.
