actually matt you are wrong.....86-91 under the seat.....92-93 below maf....there was a location change in these years.....so if it's not under the driver seat, he got the right one as long as he didn't replace the WOT/A/C cut switch

time to start searching for that short. i would get your hands on some wiring diagrams and start tracing the + wires to see where its getting its power from, a simple test light will help you with this.
