JFP1 Header Pinout Guide | Generated by AI
That maps perfectly onto the standard JFP1 layout — no ambiguity left. Here’s exactly where each wire goes:
JFP1 (2x5 header, pin 9 = key/no pin)
1 3 5 7 9(key)
2 4 6 8 10
| Your cable | JFP1 Pin | Signal |
|---|---|---|
| Power LED+ | Pin 2 | FP PWR/SLP+ |
| Power LED- | Pin 4 | FP PWR/SLP- |
| PWR SW (either wire) | Pins 6 + 8 | PWR_SW+ / PWR_SW- |
| RESET SW (either wire) | Pins 5 + 7 | RST_SW+ / RST_SW- |
Notes:
- Power LED is polarity-sensitive — make sure
+lands on pin 2 and−lands on pin 4. If you get it backwards, the LED just won’t light (no damage), so if it doesn’t turn on after boot, swap it. - PWR SW and RESET SW are not polarity-sensitive — they’re just momentary switches completing a circuit. Either wire can go on either of the two pins in their pair (6/8 for power, 5/7 for reset).
- Pins 1, 3, 10 are unused in your case (that’s the HDD LED slot you don’t have a cable for) — leave them empty.
- Pin 9 is physically missing on the header itself — that’s your orientation key, so your 2×5 connector block should naturally only seat one way.
Once wired, pressing the physical power switch should trigger boot, and the case’s power LED should light up once POST completes.
