Before you start
| Status | draft · not yet verified: nobody has reported building and running this harness |
|---|---|
| Open errors | 1: read the Findings page before cutting any wire |
| Size of the job | 70 wires · 11 connectors · 9 part lines |
| Tools | 715131-1 · wire strippers · multimeter · heat gun + heat-shrink |
| Terminals | 3-1447221-4 · 316836-1 |
| 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. |

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 | KV8-D-1 | KV8-B-34 | open (OL) | +12 V supply must not touch power ground | |
| 2 | KV8-D-1 | KV8-C-17 | open (OL) | +12 V supply must not touch sensor ground | |
| 3 | KV8-B-34 | KV8-A-16 | open (OL) | power ground must not touch +12 V supply | |
| 4 | KV8-B-34 | KV8-D-21 | open (OL) | power ground must not touch 5 V sensor reference | |
| 5 | KV8-B-34 | KV8-D-22 | open (OL) | power ground must not touch 5 V sensor reference | |
| 6 | KV8-C-17 | KV8-A-16 | open (OL) | sensor ground must not touch +12 V supply | |
| 7 | KV8-C-17 | KV8-D-21 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 8 | KV8-C-17 | KV8-D-22 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 9 | KV8-D-1 | KV8-D-21 | open (OL) | +12 V supply must not touch 5 V sensor reference | |
| 10 | KV8-D-1 | KV8-D-22 | open (OL) | +12 V supply must not touch 5 V sensor reference | |
| 11 | KV8-D-21 | KV8-A-16 | open (OL) | 5 V sensor reference must not touch +12 V supply | |
| 12 | KV8-D-22 | KV8-A-16 | open (OL) | 5 V sensor reference must not touch +12 V supply |

|---|---|---|---|
| error | REQUIRED_UNMAPPED | OEM-A-26 | Required OEM function "Camshaft position B (CMP B)" (trigger_in) is not connected to the new ECU. |
| warn | DATASET_GAP | KV8 A | 14 of 26 cavities on KV8 A have no pin data (1,2,3,4,5,6,7,8,9,12,13,14,15,19). Anything there is invisible to these checks. |
| warn | DATASET_GAP | RSX ECU A | 5 of 31 cavities on RSX ECU A have no pin data (8,13,14,17,31). Anything there is invisible to these checks. |
| warn | DATASET_GAP | RSX ECU B | 8 of 24 cavities on RSX ECU B have no pin data (11,12,14,16,19,20,22,24). Anything there is invisible to these checks. |
| warn | DATASET_GAP | RSX ECU E | 8 of 31 cavities on RSX ECU E have no pin data (10,11,12,13,17,19,25,28). Anything there is invisible to these checks. |
| warn | NET_FAMILY | OEM-E-31 ↔ KV8-B-18 | OEM-E-31 "Malfunction indicator lamp (MIL)" [low_side_out] is wired to KV8-B-18 "Aux 9" [hbridge_out]. A half-bridge can act as a low-side switch only if configured that way. |
| warn | SUPPLY_GROUP | KV8-D-21 + OEM-A-20 + OEM-E-5 + SP-5V1-1 | Supplies meant to stay independent share one net: OEM-A-20 [k_vcc2], OEM-E-5 [k_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. |
| info | NET_FAMILY | KV8-C-17 ↔ KV8-D-5 | KV8-C-17 "Analog sensor 0V reference" [sensor_ground] is wired to KV8-D-5 "Crank index sensor −" [trigger_in]. Trigger return tied to sensor/trigger ground: correct for single-ended trigger inputs. |
| info | NET_FAMILY | OEM-B-17 ↔ KV8-C-6 | OEM-B-17 "Intake air temp sensor (IAT)" [temp_in] is wired to KV8-C-6 "Analog in 5" [analog_in]. Thermistor on a plain analog input needs a pull-up; check the channel can enable one. |
| info | NET_FAMILY | OEM-B-21 ↔ KV8-B-5 | OEM-B-21 "Evap canister purge valve (PCS)" [low_side_out] is wired to KV8-B-5 "Injection 5" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | OEM-B-23 ↔ KV8-B-6 | OEM-B-23 "VTC oil control solenoid (-)" [low_side_out] is wired to KV8-B-6 "Injection 6" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | OEM-B-7 ↔ KV8-B-7 | OEM-B-7 "Reverse lockout solenoid (RVS, Type-S)" [low_side_out] is wired to KV8-B-7 "Injection 7" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | OEM-B-8 ↔ KV8-C-5 | OEM-B-8 "Coolant temp sensor (ECT)" [temp_in] is wired to KV8-C-5 "Analog in 4" [analog_in]. Thermistor on a plain analog input needs a pull-up; check the channel can enable one. |
| info | NET_FAMILY | OEM-E-21 ↔ KV8-B-8 | OEM-E-21 "Evap vent shut valve (VSV)" [low_side_out] is wired to KV8-B-8 "Injection 8" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
