Before you start
| Status | draft · not yet verified: nobody has reported building and running this harness |
|---|---|
| Open errors | 2: read the Findings page before cutting any wire |
| Size of the job | 68 wires · 11 connectors · 9 part lines |
| Tools | Crimp and extraction tools for each terminal family (see Connectors) · wire strippers · multimeter · heat gun + heat-shrink |
| Terminals | 3-1447221-4 |
| Order of work | 1. Check every part against the parts list. 2. Cut and label every wire (labels: Export → Wire labels). 3. Crimp and pin connector by connector, ticking the build checklist. 4. Run the bench test with nothing plugged in and the battery disconnected. 5. Only then connect the ECU and power up. |
Build checklist
Tick each box as you go. Continuity: meter from end to end, expect under 1 Ω.

Bench test (before first power-up)
Battery disconnected, ECU and every sensor unplugged. Meter on resistance. Each pair below must read open (OL): a reading means a pinched wire, a stray strand or a mis-pinned cavity. Then check continuity of every wire (last column of the build checklist).
| # | Probe A | Probe B | Expect | Why | Reading |
|---|---|---|---|---|---|
| 1 | EMUPRO16-B-14 | EMUPRO16-A-11 | open (OL) | +12 V supply must not touch power ground | |
| 2 | EMUPRO16-B-14 | EMUPRO16-A-20 | open (OL) | +12 V supply must not touch sensor ground | |
| 3 | EMUPRO16-A-11 | EMUPRO16-A-12 | open (OL) | power ground must not touch 5 V sensor reference | |
| 4 | EMUPRO16-A-11 | EMUPRO16-B-12 | open (OL) | power ground must not touch 5 V sensor reference | |
| 5 | EMUPRO16-A-20 | EMUPRO16-A-12 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 6 | EMUPRO16-A-20 | EMUPRO16-B-12 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 7 | EMUPRO16-B-14 | EMUPRO16-A-12 | open (OL) | +12 V supply must not touch 5 V sensor reference | |
| 8 | EMUPRO16-B-14 | EMUPRO16-B-12 | open (OL) | +12 V supply must not touch 5 V sensor reference |
