Quick answer
Current blueprint data lists Wiring Kit as Silver plus Copper Wire. The usual blocker is Silver, while Copper Wire is the easy piece to forget at base. PC Gamer currently routes Rebreather through System Chip, and System Chip routes back to Wiring Kit, so this small part now matters for deep-diving equipment too.
Field notes for Wiring Kit runs
Treat it as a Silver route, not a desk craft
The Fabricator click is the easy part. The trip is really about making Silver repeatable enough that one Wiring Kit does not empty your upgrade plan.
Leave Copper Wire visible
Copper Wire is basic, which is exactly why it disappears into the wrong locker. Keep two coils in the electronics box before you start batch crafting.
Stop one step before the chip
If the next blueprint asks for Wiring Kit directly, a finished System Chip will not help. Hold the kit until the target recipe is on screen.
Wiring Kit craft plan
Fix the Silver route first
If Wiring Kit is blocked, the problem is usually Silver. Run the Old Habitat cave route or your best repeatable Silver loop before you start blaming the fabricator.
Keep Copper Wire beside Silver
Copper Wire looks basic, so it often sits in a different locker from electronics. Store a few coils with Silver, Quartz, and chips so the recipe check is fast.
Craft against a named recipe
Wiring Kit is useful, but it is less flexible than raw Silver plus Copper Wire. Make it when System Chip, a station, a tool, or a vehicle upgrade actually needs it.
Check the System Chip chain
System Chip currently sits right after Wiring Kit in the electronics chain. If a Rebreather, Scanner Station, Tadpole, or depth module plan is stuck, trace the chain back here before blaming the final upgrade.
Leave a raw Silver reserve
One spare Wiring Kit is fine once Silver is steady. Before that, keep at least a couple of Silver pieces uncrafted so a patch-sensitive recipe does not trap you.

Wiring Kit checklist
| Item | What to confirm |
|---|---|
| Silver | The real bottleneck for most early Wiring Kit and System Chip crafts. |
| Copper Wire | Craft from Copper and store with electronics, not only basic materials. |
| System Chip | The next electronics step, usually paired with Quartz in current guides and used by Rebreather. |
| Upgrade target | Confirm the recipe before turning every raw material into finished kits. |
| Locker split | Keep raw Silver, Copper Wire, Wiring Kit, and Quartz in one electronics box. |
Do not convert every Silver piece
A neat stack of Wiring Kits feels productive, but finished parts can corner you. Keep some Silver and Copper Wire loose until the next recipe is visible on your fabricator or station.
FAQ
How do you make Wiring Kit in Subnautica 2?
Current blueprint data lists Wiring Kit as Silver plus Copper Wire. If the craft is blocked, check your Silver route first, then make sure you already turned Copper into Copper Wire.
What is Wiring Kit used for?
It feeds electronics chains, especially System Chip. Current guide data also connects those electronics to tools, stations, vehicle prep, and depth-related upgrades.
Should I stockpile Wiring Kits early?
Not heavily. One spare is useful after Silver becomes repeatable, but raw Silver and Copper Wire are more flexible while recipes are still patch-sensitive.
Why am I stuck making System Chip?
System Chip usually sends you back to Wiring Kit, and Wiring Kit sends you back to Silver. Solve that material chain in order instead of searching for the chip recipe alone.
