The following is a "how-to" on wiring your bricks up the way Nissan intended!
Materials:Silvia non-projector headlights wire cutterswire stripperselectrical tape (pick a your own color)soldering iron (optional)male & female spade connectors (also optional)
The 240 harness has:red/blue wire (+)red/green wire (-)red/white wire (ALT)
The non-projector lights have 2 harnesses:
two wire harness:red (+)black (-)
three wire harness:red (+)black (-)green (ALT)
First off, don't be a dummy. Disconnect the (+) on your battery.
Second, strip all wires exposing at least an inch of wire on all of them.
On the stock 240 harness for the headlights there are 3 wires attached to the 3 prong (H4) connector, get it and cut the adapter off. you won't need it anymore unless you either plan on keeping the ugly flip up headlights or the equally ugly projector lights. If you wanna swap them out later, it will be plug-n-play. All you have to do is splice the wires a little instead of cutting it completely.
The bricks have 5 wires total. The colors are black, red on one harness and black, red, and green on the other harness. This will be easier if you separate the two harnesses' wires.
Take the black wire from the two-wire harness and twist it together with the red/green wire (-) from the 240 harness.
Then take the black wire from the three-wire harness and twist it with the red/green wire from the 240 harness also. You can solder it then tape it or just tape it.
Next take the red wire from the two-wire harness and twist it together with the red/blue (+) wire from the 240 harness. Solder and tape it or just tape it.
Now that the two-wire harness is finished, take the green wire from the three-wire harness and twist it together with the red/white (alt) wire from the 240 harness. Solder and tape it or just tape it.
Now for the red wire from the three-wire harness. This one is completely optional. If you twist this together with the red/blue wire from the 240 harness then when you put your high beams on the low beams will stay on. If not then tape this wire off somewhere out of the way.
Now plug the two- & three-wire plugs into the corresponding places on the non-projector headlights then install the lights onto the Silvia brackets and fenders.
Guess what? You're done. Install HID look-a-like bulbs and enjoy. Now you can see when there are no street lights on at night without sitting up close to the windshield.
**Note** I left the spade connectors optional because they can be substituted for soldering.
