Order of work1. 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).

Auto-mapped by auto_map() from the library pin data on 2026-10-06. Review every wire against both manuals before building. Open items: - OEM-E9 25: Camshaft position 2 (G2): no free cam_vr/cam_hall/frequency_in input on Emtron KV8 Not wired: - OEM-E10 33: Battery constant (BATT): Emtron KV8 has no battery-constant input; not needed - KV8-D 12: Knock 1 − left open: the stock knock sensor has one ECU wire; check the ECU manual for single-wire knock sensors - KV8-D 18: Knock 2 − left open: the stock knock sensor has one ECU wire; check the ECU manual for single-wire knock sensors - OEM-E10 16: Tachometer output: no free tacho/frequency_out/low_side/ls_hs on Emtron KV8
