S13.4 Conversion headlights
 

Hey guys this how you wire up the headlights. The method I used is to go to a junk yard find a S 14 headlight harness. It make it easy to do.
1. The s13 headlight harness varies from year to year.
2. The s13 has 3 wires. Pink and black, green, and red and blue.
3. On s14 harness u have the red and blue and black for low beams
4. S14 has a red and green for the high beams but these also varies from year to year.

1. Take s14 harness low beams, (red & blue) wire into the s13 (green wire).
2. Take the s14 high beam(red & blue wire) harness and wire into s13 (red & green).
3. Take both ground wires from s14 which are (black), and wire into the s13 (pink & black) wire which are ground wires.
(Note: these colors for the wiring varies from year to year. This is for a 91 s13.)
