ok well i can help with that...mine is a 92 but i think they are the same....... if you look under the dash and you see the clutch switch there are two wires coming out of it.... blue and black....those two wires go into a white connector next to the clutch switch and come out of the white connector as a green and black....splice into the green wire with a scotch lock, (that is what i call them), and run that wire to pin 104 at the ecu....i would put a diode in the wire that you run to the ecu so there is no chance of a back feed of voltage...if that makes since....
pin 104 at the ECU is in small connector and the color is black and yellow.....it is the second wire on the top row..
