Before you start
Not confident with automotive wiring? Have a professional harness builder or tuner do it, or check your work before first power-up. A wiring mistake can damage the ECU, the engine or the car, or start a fire.
| Status | proposal · not yet verified: nobody has reported building and running this harness |
|---|---|
| Open errors | none |
| Size of the job | 78 wires · 14 connectors · 0 part lines |
| Tools | Crimp and extraction tools for each terminal family (see Connectors) · wire strippers · multimeter · heat gun + heat-shrink |
| 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 | MAIN-R-COIL- | MAIN-R-COIL+ | open (OL) | power ground must not touch +12 V supply | |
| 2 | MAIN-R-COIL- | MAIN-R-OUT | open (OL) | power ground must not touch +12 V supply | |
| 3 | MAIN-R-COIL- | NEW-BATT-1 | open (OL) | power ground must not touch +12 V supply | |
| 4 | MAIN-R-COIL- | OEM-E15-16 | open (OL) | power ground must not touch +12 V supply | |
| 5 | MAIN-R-COIL- | PROTEUS-White35-10 | open (OL) | power ground must not touch 5 V sensor reference | |
| 6 | PROTEUS-White35-1 | MAIN-R-COIL+ | open (OL) | sensor ground must not touch +12 V supply | |
| 7 | PROTEUS-White35-1 | MAIN-R-OUT | open (OL) | sensor ground must not touch +12 V supply | |
| 8 | PROTEUS-White35-1 | NEW-BATT-1 | open (OL) | sensor ground must not touch +12 V supply | |
| 9 | PROTEUS-White35-1 | OEM-E15-16 | open (OL) | sensor ground must not touch +12 V supply | |
| 10 | PROTEUS-White35-1 | PROTEUS-White35-10 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 11 | PROTEUS-White35-10 | MAIN-R-COIL+ | open (OL) | 5 V sensor reference must not touch +12 V supply | |
| 12 | PROTEUS-White35-10 | MAIN-R-OUT | open (OL) | 5 V sensor reference must not touch +12 V supply | |
| 13 | PROTEUS-White35-10 | NEW-BATT-1 | open (OL) | 5 V sensor reference must not touch +12 V supply | |
| 14 | PROTEUS-White35-10 | OEM-E15-16 | open (OL) | 5 V sensor reference must not touch +12 V supply |
If any reading doesn't match, stop and get help before powering up.

Notes
Auto-mapped by auto_map() from the library pin data on 2026-10-19. Review every wire against both manuals before building. Not wired: - OEM-E15 1: Battery constant (+12V): rusEFI Proteus has no battery-constant memory input; not needed - OEM-E11 28: VVT oil-control valve RH (OCR−): no free low_side/relay_control/heater_low_side/ls_hs/injector on rusEFI Proteus - OEM-E12 12: Throttle magnetic clutch + (CL+): no free low_side/relay_control/heater_low_side/ls_hs/injector on rusEFI Proteus - OEM-E13 8: Throttle magnetic clutch − (CL−): no free low_side/relay_control/heater_low_side/ls_hs/injector on rusEFI Proteus - OEM-E14 19: VVT oil-control valve LH (OCV−): no free low_side/relay_control/heater_low_side/ls_hs/injector on rusEFI Proteus - OEM-E14 29: ACIS induction VSV: no free low_side/relay_control/heater_low_side/ls_hs/injector on rusEFI Proteus - OEM-E15 6: Check engine light (W): no free low_side/relay_control/heater_low_side/ls_hs/injector on rusEFI Proteus - OEM-E15 11: OBD-II / DLC3 data (SIL): no free k_line on rusEFI Proteus - OEM-E11 5: Diagnostic test (TC): no free k_line on rusEFI Proteus
