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 | 101 wires · 9 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. |
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 | T12-C1-31 | T12-C1-13 | open (OL) | +12 V supply must not touch power ground | |
| 2 | T12-C2-24 | T12-C1-13 | open (OL) | 5 V sensor reference must not touch power ground | |
| 3 | T12-C3-26 | T12-C1-13 | open (OL) | +12 V supply must not touch power ground | |
| 4 | T12-C1-31 | T12-C2-24 | open (OL) | +12 V supply must not touch 5 V sensor reference | |
| 5 | T12-C2-21 | T12-C1-31 | open (OL) | sensor ground must not touch +12 V supply | |
| 6 | T12-C2-21 | T12-C2-24 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 7 | T12-C2-21 | T12-C3-26 | open (OL) | sensor ground must not touch +12 V supply | |
| 8 | T12-C3-26 | T12-C2-24 | 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.

Notes
Fit check: unconfirmed. Confirm these before building: - Needs CAN (GM E38 (C6 Corvette)); not documented for this ECU - Trigger pattern for GM LS not found in the ECU's docs (No GM/LS entry in any DTAFast manual.) 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-X2 6: Throttle actuator motor control 1: no +/− pair in the pinout (multi-phase or half-documented motor); wire by hand - OEM-X2 5: Throttle actuator motor control 2: no +/− pair in the pinout (multi-phase or half-documented motor); wire by hand - T12-C3 27: Permanent 12v: required by DTAFast T12 but no stock pin feeds it; wire by hand Not wired: - OEM-X2 29: Knock sensor 2 signal A: no free knock input on DTAFast T12 - OEM-X2 30: Knock sensor 2 signal B: no free knock input on DTAFast T12 - OEM-X2 32: Generator field duty control: no free low_side/relay_control/heater_low_side/ls_hs/injector on DTAFast T12 - OEM-X2 61: Charge indicator signal: no free low_side/relay_control/heater_low_side/ls_hs/injector on DTAFast T12 - OEM-X2 8: EVAP canister purge solenoid: no free low_side/relay_control/heater_low_side/ls_hs/injector on DTAFast T12 - OEM-X1 48: Tachometer output: no free tacho/frequency_out/low_side/ls_hs on DTAFast T12 - OEM-X1 57: VSS output to ABS (128k): no free frequency_out/tacho/low_side/ls_hs on DTAFast T12 - OEM-X1 18: Accessory wakeup serial data (5985): no free k_line on DTAFast T12
