As part of tearing down my dads S15 Gypsy, I had to take care of some wiring that got chewed up. Now the original set-up had 2 relays (I've been told those are for the A/C & fuel pump). I got a 3 relay block from a '94 Bravada. Thankfully, the 2 relays lined up great. Now I need to figure out the 3rd relay, if memory serves there is a yellow wire, pink w/ black stripe, 2 black wires, and another wire I cant think of.
Can anyone tell me which of these wires does what? I'm asking because I want to add an ooooga horn (hopefully the relay can handle 30amps).


TIA, Jeremiah
