[QUOTE="machoheadgames, post: 431728, member: 18789"] Unfortunately 91 is the weird year where the gauges are still old front-lit style and a mechanical speedo yet has all the fancy new fuel injection. As a result, the wiring harnesses almost from 91 almost never match the other years. A lot of the functions are the exact same but wiring colors are not. You might try to ebay find a 91 PDC (the relay/fuse box you're talking about). If you cant find them, you'll have to start figuring out things with a meter and lots of detective work to figure out what all of the old wires did and what you will splice them to on your own new wiring in the box.
