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 | 3: read the Findings page before cutting any wire |
| Size of the job | 77 wires · 10 connectors · 2 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. |

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 | T12-C2-24 | T12-C2-21 | open (OL) | 5 V sensor reference must not touch sensor ground | |
| 2 | T12-C1-13 | T12-C1-31 | open (OL) | power ground must not touch +12 V supply | |
| 3 | T12-C1-13 | T12-C2-24 | open (OL) | power ground must not touch 5 V sensor reference | |
| 4 | T12-C1-13 | T12-C3-26 | open (OL) | power ground must not touch +12 V supply | |
| 5 | T12-C2-21 | T12-C1-31 | open (OL) | sensor ground must not touch +12 V supply | |
| 6 | T12-C2-21 | T12-C3-26 | open (OL) | sensor ground must not touch +12 V supply | |
| 7 | T12-C2-24 | T12-C1-31 | open (OL) | 5 V sensor reference must not touch +12 V supply | |
| 8 | T12-C2-24 | T12-C3-26 | 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
Fit check: unconfirmed. Confirm these before building: - Trigger pattern for Toyota 1JZ-GTE not found in the ECU's docs (T-Win sensor table lists 2JZ/1UZ but omits 1JZ.) Auto-mapped by auto_map() from the library pin data on 2026-10-11. Review every wire against both manuals before building. Open items: - OEM-C86 9: Ignition switch (IGSW): key-on 12 V sense — optional in a swap (the main relay is energized from keyed 12 V, not from this pin); DTAFast T12 has no dedicated key-on input - T12-C3 27: Permanent 12v: required by DTAFast T12 but no stock pin feeds it; wire by hand Not wired: - OEM-C88 14: Neutral/park switch (NSW): no free switch_in/frequency_in/analog_0_5 on DTAFast T12 - OEM-C88 31: TRAC throttle idle switch (IDL2): no free switch_in/frequency_in/analog_0_5 on DTAFast T12 - OEM-C88 32: TPS idle switch (IDL1): no free switch_in/frequency_in/analog_0_5 on DTAFast T12 - OEM-C85 11: Slave TRAC throttle position (VTO2): no free analog_out on DTAFast T12 - OEM-C85 7: Slave throttle position (VTO1): no free analog_out on DTAFast T12 - OEM-C88 19: Voltage feedback (VF): no free analog_out on DTAFast T12
