im confused on where the 86 wire on the relay is supposed to go. the instructions say it goes to pimp pin 52 but im not sure which wire that is. if anyone has a pic of how they wired the stock fan on a na 92 lx that would help a lot

The harness connector that plugs into the ECU is numbered in the corners (1, 20, 40, 60). That gives you the ability to count from 60 back to 52 to locate pin location 52.

im just trying to wire in the relay to control the fan. i figured it would be a wire under the hood with the rest of them

Many wires under the hood go to the ECU. It doesn't matter if you connect to it at the ECU or at the other end of that wire under the hood, the end result is the same. The 91-93 Mustangs use pin 51 for fan in stock form. So you're moving pin 51 to 52 or 55 (whichever one you didn't move pin 32 to when following the DIS specific section of the startup guide). The relay is in the IRCM "box" on the passenger side strut tower so you don't have to add a new relay (though you can if you'd prefer).
