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 | draft · not yet verified: nobody has reported building and running this harness |
|---|---|
| Open errors | none |
| Size of the job | 67 wires · 11 connectors · 5 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 | M170-A-23 | M170-A-11 | open (OL) | +12 V supply must not touch sensor ground | |
| 2 | M170-A-23 | M170-A-14 | open (OL) | +12 V supply must not touch power ground | |
| 3 | M170-A-34 | M170-A-11 | open (OL) | 5 V sensor reference must not touch sensor ground | |
| 4 | M170-A-11 | M170-A-16 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 5 | M170-A-11 | RLY1-R-OUT | open (OL) | sensor ground must not touch +12 V supply | |
| 6 | M170-A-14 | M170-A-16 | open (OL) | power ground must not touch 5 V sensor reference | |
| 7 | M170-A-14 | M170-A-34 | open (OL) | power ground must not touch 5 V sensor reference | |
| 8 | M170-A-14 | RLY1-R-OUT | open (OL) | power ground must not touch +12 V supply | |
| 9 | M170-A-23 | M170-A-16 | open (OL) | +12 V supply must not touch 5 V sensor reference | |
| 10 | M170-A-23 | M170-A-34 | open (OL) | +12 V supply must not touch 5 V sensor reference | |
| 11 | M170-A-34 | RLY1-R-OUT | open (OL) | 5 V sensor reference must not touch +12 V supply | |
| 12 | RLY1-R-OUT | M170-A-16 | open (OL) | +12 V supply must not touch 5 V sensor reference |
If any reading doesn't match, stop and get help before powering up.

| warn | DBW_SHARED_5V | M170-A-34 + OEM-A-20 + OEM-A-21 + OEM-E-5 + SP-5V1-1 | These 5 V supplies are separate in the stock car (OEM-A-20 [s2k_vcc2], OEM-A-21 [s2k_vcc1], OEM-E-5 [s2k_vcc3]) and here share one ECU 5 V (M170-A-34). On a drive-by-wire car the OEM splits them so one short or fault can't corrupt both throttle/pedal tracks at once. M170 has 2 5 V sensor supply pin(s). All are in use, so decide: accept the shared supply (and rely on the ECU's DBW fault checks), or add a separate regulated 5 V for the sub tracks. |
| warn | LOAD_UNKNOWN | RLY1-R-OUT | RLY1-R-OUT "Relay contact output (switched +12 V to load)" drives OEM-B-6 VTEC solenoid (load 1.0 A) but its current rating is unknown. Check the ECU manual. |
| warn | NET_FAMILY | OEM-A-6 ↔ M170-A-56 | OEM-A-6 "Cam position sensor (T2)" [trigger_in] is wired to M170-A-56 "Universal Digital Input 2" [digital_in]. Hall-type cam/speed signals can use a digital input if it handles the frequency; VR signals cannot. |
| warn | NET_FAMILY | OEM-A-7 ↔ M170-A-49 | OEM-A-7 "Crank position sensor (T1)" [trigger_in] is wired to M170-A-49 "Universal Digital Input 1" [digital_in]. Hall-type cam/speed signals can use a digital input if it handles the frequency; VR signals cannot. |
| warn | SUPPLY_GROUP | M170-A-34 + OEM-A-20 + OEM-A-21 + OEM-E-5 + SP-5V1-1 | Supplies meant to stay independent share one net: OEM-A-20 [s2k_vcc2], OEM-A-21 [s2k_vcc1], OEM-E-5 [s2k_vcc3]. The new ECU has no free 5 V reference, so they share one: normal on a standalone, but a short on any of these sensors drops them all. |

Notes
Fit check: unconfirmed. Confirm these before building: - Throttle motor draws ≥ ~14 A at stall; peak/stall limit not documented for this ECU (12.0 A continuous rating) Auto-mapped by auto_map() from the library pin data on 2026-10-11. Review every wire against both manuals before building. Not wired: - OEM-E 9: Ignition signal: key-on 12 V sense — optional in a swap (the main relay is energized from keyed 12 V, not from this pin); MoTeC M170 has no dedicated key-on input - OEM-E 8: A/F sensor heater relay: no free relay_control/low_side/heater_low_side/ls_hs/injector rated ≥ 0.2 A on MoTeC M170 - OEM-E 21: Secondary O2 heater: no free heater_low_side/low_side/relay_control/ls_hs/injector on MoTeC M170 - OEM-A 10: A/F sensor heater: no free heater_low_side/low_side/relay_control/ls_hs/injector on MoTeC M170 - OEM-B 15: Engine mount control solenoid: no free low_side/relay_control/heater_low_side/ls_hs/injector on MoTeC M170 - OEM-B 18: Alternator control: no free low_side/relay_control/heater_low_side/ls_hs/injector on MoTeC M170 - OEM-B 21: Evap canister purge valve: no free low_side/relay_control/heater_low_side/ls_hs/injector on MoTeC M170 - OEM-E 19: Evap canister vent shut valve: no free low_side/relay_control/heater_low_side/ls_hs/injector on MoTeC M170 - OEM-E 25: Engine speed pulse (tacho): no free tacho/frequency_out/low_side/ls_hs on MoTeC M170 - OEM-E 26: Vehicle speed output: no free frequency_out/tacho/low_side/ls_hs on MoTeC M170 - OEM-E 15: Electrical load detector: no free analog_0_5 on MoTeC M170 - OEM-E 16: Power steering load detector: no free analog_0_5 on MoTeC M170 - OEM-D 9: Cruise clutch signal: no free switch_in/frequency_in/analog_0_5 on MoTeC M170 - OEM-E 22: Brake pedal switch: no free switch_in/frequency_in/analog_0_5 on MoTeC M170 - OEM-E 28: A/C switch signal: no free switch_in/frequency_in/analog_0_5 on MoTeC M170 - OEM-E 13: Multiplex communication: no free k_line on MoTeC M170 - OEM-A 28: A/F sensor signal −: not classified in the library; wire by hand - OEM-A 31: A/F sensor signal +: not classified in the library; wire by hand - OEM-B 10: Alternator L signal: not classified in the library; wire by hand - OEM-B 19: Throttle actuator command to throttle control module (SEFD): not classified in the library; wire by hand - OEM-B 20: Throttle actuator command to throttle control module (SEDF): not classified in the library; wire by hand - OEM-E 27: Immobilizer code: not classified in the library; wire by hand - OEM-E 29: Service check signal: not classified in the library; wire by hand - OEM-E 30: Write enable signal: not classified in the library; wire by hand
