This is assuming you have a stock and fully functional S13 coupe and a stock and fully functional stock Silvia S13 triple projector front end.
Your old front end has side markers for parking, low/hi in the popup, and parking/signal combo in the bumper.
Your new front end has white corner light for parking, low/high/fog in the tri-projector, and parking/signal combo in the bumper. There is also an amber portion in the corner light as well.
There is no one way to wire up the front end. The following is the way I recommend. It's not necessarily right or the only way.
Bumper lights are plug and play. Use everything up to the bulb in the new lens. You may even be able to reuse your existing bumper lens if you have pignose.
Hi/lo take the rectangular 3-prong plug from the body harness and plugs directly to the 3-prong plug on the projector. Plug and play.
For sidemarker parking, use everything up to the bulb from your existing side marker. Plug and play.
For the amber portion of the side marker, you'll need a thin 3-prong 194 bulb holder if your front end didn't come with one. You can wire the bulb up to the turn signal wire from the bumper light. The FSM tells you that it's green/yellow for the right side and green/black on the left. Connect the other side of the bulb to ground.
For fog, Silvias come with H3C, which is hard to find in the US. If you need easy replacement, you can change to H3. H3/H3C use spade terminals. Take the bulb to your auto parts store and you'll see the female terminals that fit.
If you use H3 and have the stock Silvia harness, it's plug and play to the bulb.
If you convert to H3C, you'll need to run one spade to the bulb and another one for the bulb holder. H3 grounds through the housing of the bulb whereas H3C grounds to a second spade terminal next to the power terminal.
Whichever way you wire up your fog, you need to supply current and ground. There are many ways. I like to reuse the existing retractor switch to control the fog independently of the low/hi.
Connect one side of the fog to the brown wire that used to go to the headlight motor, and the other side of the fog to ground. See below.

Same as above minus fog.
