Diablo Chip Codes
A friend of mine has a 02 ranger with 4.0 v-6 and he is trying to order a Diablo chip. does anyone know where he would find the computer code at. Motorhaven said it was suppose to be under hood on passenger side on fire wall but there is no sticker there. Any help would be greatly appreciated. Thanks

 

The computer box is on the top/center of the firewall, offset slightly to the passnger side. It has a wiring harness bolted to the center of it with a 10mm bolt. The code is on a white sticker on that box. Also, on the passenger side door frame.
