Cybertruck Roof Glass & Starlink Mini

Not all Cybertruck roof glass is created equal. If you're planning to mount a Starlink Mini underneath the glass (interior mount), you need to know which glass type you have. This determines whether the signal can pass through.

The Three Glass Types

Tesla has shipped three different roof glass configurations on the Cybertruck:

• 1st Gen Silver Glass — The original silver-tinted glass shipped on early production Cybertrucks. Has a metallic coating that blocks RF signals.
• 2nd Gen Silver Glass — Updated silver glass with a revised coating. Allows RF signals (including Starlink) to pass through from underneath.
• Black Glass — Darker tinted glass option. Blocks RF signals similar to 1st gen silver.

Starlink Mini Compatibility

How to Identify Your Glass

• Production date — Earlier VINs are more likely to have 1st gen silver. Later production runs switched to 2nd gen.
• Visual inspection — 2nd gen silver has a slightly different tint compared to 1st gen. Black glass is obvious — it's visibly darker.
• Signal test — Place a Starlink Mini on the inside of the glass and check for signal. If it connects, you have 2nd gen silver.

Recommendation

If you have 2nd gen silver glass, go with an interior mount. Cleaner install, no wind noise, no theft risk.

If you have 1st gen silver or black glass, use an exterior mount. Signal performance will actually be slightly better since there's no glass attenuation at all.

Winch Wiring Guide — 240v AC

Last verified April 2026

This guide covers how to power a 12,000 lb winch using the Cybertruck's 240v 50A plug and four ATX-style power supplies wired in parallel. The 240v is split to all four PSUs. The DC side wiring is up to you.

Concept

The Cybertruck's 240v 50A plug provides the power. That 240v is split to four ATX-style power supplies which convert it to 12v DC. The four PSUs wired in parallel provide enough current to run the winch motor. The trick is getting the PSUs to turn on without a motherboard — that's where the pin jumpers come in.

Parts List

AC Side Wiring

The AC side is straightforward: the CT's 240v 50A plug is split to all four power supplies via the appropriate cables. The three cable types handle the distribution from the 240v plug to all four PSUs.

PSU Pin Configuration

ATX power supplies need two modifications to run without a motherboard:

1. Signal Wire — Pin 34 (PS_ON)

Wire all pin 34s together across all four power supplies using the signal wire. Pin 34 is the PS_ON signal — grounding it tells the PSU to turn on. By wiring them together, all four PSUs turn on and off simultaneously.

2. Resistor Jump — Pins 33 & 36

Use a low-ohm resistor to jump pins 33 and 36 on each PSU. This provides a minimum load on the 3.3v rail, which some PSUs require to regulate their 12v output properly. Without this, the PSU may not start or may output unstable voltage.

DC Side Wiring

How you wire up the DC side is up to you. The four PSUs' 12v outputs need to be combined and connected to the winch motor's power terminals. Common approaches include bus bars, heavy-gauge parallel runs, or custom harnesses.

• Use wire gauge appropriate for the current draw (the winch can pull 400+ amps at full load across all PSUs)
• Keep DC runs as short as possible to minimize voltage drop
• Use proper crimped terminals — no wire nuts on high-current DC
• Fuse each PSU output individually for safety
