How To: S13 to S15 High Beam Wiring

[KiLLeR2001]

After following the wiring diagram from Yoshi's website... Yoshi's S13-S15 Conversion

I noticed that when I would switch on my high beams my low beams would cut off. Doing some more research I realized that this is not how the S15 headlights are suppose to function as the low and high beams should be on when the high beams are on. This is because the way the S13's sealed headlight functions.

So if you want a quick little fix on how to have your highs and lows on when the high's are triggered read ahead...

Things you'll need:

2 Bosch Relays
8 gauge wire
12 gauge wire
30A Fuse
Soldering iron / solder
Electrical Tape
Wire Cutters

Assuming you've already followed Yoshi's diagram to wire up your headlights, simply follow this diagram of how the relay's are wired up and everything will work properly. Shouldn't take too long to finish, I did it in an hour or so.

you can also use the power wire from the headlight motor to power the headlights.

then you when you put the high beams on the headlights will stay on.
