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 | 65 wires · 10 connectors · 7 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 | SHADOW8-A-1 | SHADOW8-A-34 | open (OL) | +12 V supply must not touch power ground | |
| 2 | SHADOW8-A-1 | SHADOW8-A-4 | open (OL) | +12 V supply must not touch sensor ground | |
| 3 | SHADOW8-B-1 | SHADOW8-A-4 | open (OL) | +12 V supply must not touch sensor ground | |
| 4 | SHADOW8-A-1 | SHADOW8-A-3 | open (OL) | +12 V supply must not touch 5 V sensor reference | |
| 5 | SHADOW8-A-34 | SHADOW8-A-3 | open (OL) | power ground must not touch 5 V sensor reference | |
| 6 | SHADOW8-A-34 | SHADOW8-B-1 | open (OL) | power ground must not touch +12 V supply | |
| 7 | SHADOW8-A-4 | SHADOW8-A-3 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 8 | SHADOW8-B-1 | SHADOW8-A-3 | open (OL) | +12 V supply must not touch 5 V sensor reference |

| error | PHYS_REQUIRED_OPEN | SHADOW8-B-21 | SHADOW8-B-21 "Digital input 10 / ignition switch" is required but not wired. |
| warn | NET_FAMILY | OEM-A-2 ↔ SHADOW8-B-22 | OEM-A-2 "Air control valve solenoid" [low_side_out] is wired to SHADOW8-B-22 "Aux output 9" [hbridge_out]. A half-bridge can act as a low-side switch only if configured that way. |
| warn | NET_FAMILY | OEM-A-3 ↔ SHADOW8-B-23 | OEM-A-3 "Evap bypass solenoid" [low_side_out] is wired to SHADOW8-B-23 "Aux output 10" [hbridge_out]. A half-bridge can act as a low-side switch only if configured that way. |
| warn | NET_FAMILY | OEM-A-4 ↔ SHADOW8-B-24 | OEM-A-4 "Evap canister vent shut valve" [low_side_out] is wired to SHADOW8-B-24 "Aux output 11" [hbridge_out]. A half-bridge can act as a low-side switch only if configured that way. |
| warn | NET_FAMILY | OEM-A-6 ↔ SHADOW8-B-25 | OEM-A-6 "Evap canister purge valve" [low_side_out] is wired to SHADOW8-B-25 "Aux output 12" [hbridge_out]. A half-bridge can act as a low-side switch only if configured that way. |
| warn | SUPPLY_GROUP | OEM-C-19 + OEM-C-28 + SHADOW8-A-3 + SP-5V1-1 | Supplies meant to stay independent share one net: OEM-C-19 [s2k_vcc1], OEM-C-28 [s2k_vcc2]. 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 | OEM-A-1 ↔ SHADOW8-B-7 | OEM-A-1 "Coolant temp gauge drive" [low_side_out] is wired to SHADOW8-B-7 "Injector cylinder 6" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | OEM-A-12 ↔ SHADOW8-B-8 | OEM-A-12 "Immobilizer indicator light" [low_side_out] is wired to SHADOW8-B-8 "Injector cylinder 7" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | OEM-A-18 ↔ SHADOW8-B-9 | OEM-A-18 "Check engine light (MIL)" [low_side_out] is wired to SHADOW8-B-9 "Injector cylinder 8" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | OEM-A-28 ↔ SHADOW8-B-14 | OEM-A-28 "Air pump relay" [low_side_out] is wired to SHADOW8-B-14 "Aux output 5" [switch_out]. Configure this output as low side. |
| info | NET_FAMILY | OEM-B-12 ↔ SHADOW8-B-15 | OEM-B-12 "VTEC solenoid" [high_side_out] is wired to SHADOW8-B-15 "Aux output 6" [switch_out]. Configure this output as high side. |
| info | NET_FAMILY | OEM-B-23 ↔ SHADOW8-B-6 | OEM-B-23 "Idle air control valve" [low_side_out] is wired to SHADOW8-B-6 "Injector cylinder 5" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | OEM-C-1 ↔ SHADOW8-B-16 | OEM-C-1 "Primary O2 heater" [low_side_out] is wired to SHADOW8-B-16 "Aux output 7" [switch_out]. Configure this output as low side. |
| info | NET_FAMILY | OEM-C-11 ↔ SHADOW8-B-17 | OEM-C-11 "Secondary O2 heater control" [low_side_out] is wired to SHADOW8-B-17 "Aux output 8" [switch_out]. Configure this output as low side. |
| info | NET_FAMILY | OEM-C-25 ↔ SHADOW8-A-19 | OEM-C-25 "Intake air temp sensor" [temp_in] is wired to SHADOW8-A-19 "Analog voltage 7 (switchable 1k pull-up)" [analog_in]. Thermistor on a plain analog input needs a pull-up; check the channel can enable one. |
| info | NET_FAMILY | OEM-C-26 ↔ SHADOW8-A-18 | OEM-C-26 "Coolant temp sensor" [temp_in] is wired to SHADOW8-A-18 "Analog voltage 6" [analog_in]. Thermistor on a plain analog input needs a pull-up; check the channel can enable one. |
| info | NET_FAMILY | OEM-C-9 ↔ SHADOW8-A-7 | OEM-C-9 "Crank sensor − (CKP−)" [trigger_in] is wired to SHADOW8-A-7 "Trigger ground" [sensor_ground]. Trigger return tied to sensor/trigger ground: correct for single-ended trigger inputs. |
