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.

Statusdraft · not yet verified: nobody has reported building and running this harness
Open errors1: read the Findings page before cutting any wire
Size of the job57 wires · 6 connectors · 0 part lines
ToolsCrimp and extraction tools for each terminal family (see Connectors) · wire strippers · multimeter · heat gun + heat-shrink
Order of work1. 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 AProbe BExpectWhyReading
1P8-C1-10P8-C1-46open (OL)5 V sensor reference must not touch sensor ground
2P8-C1-19P8-C1-15open (OL)+12 V supply must not touch power ground
3P8-C1-19P8-C1-46open (OL)+12 V supply must not touch sensor ground
4P8-C1-15P8-C1-10open (OL)power ground must not touch 5 V sensor reference
5P8-C1-19P8-C1-10open (OL)+12 V supply must not touch 5 V sensor reference

If any reading doesn't match, stop and get help before powering up.

errorINJECTOR_BALLASTP8The 2JZ-GTE injectors (2JZ-GTE fuel injector) are low-impedance, but P8 drives saturated (high-Z) injectors only. Add a ballast resistor pack in series with each injector, or use an ECU with low-Z / peak-and-hold injector drivers.
warnLOAD_UNKNOWNP8-C1-41P8-C1-41 "Fuel Pump Relay" drives OEM-E10-23 A/C clutch relay (ACMG) (load 0.2 A) but its current rating is unknown. Check the ECU manual.

Notes

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-E10 33: Battery constant (BATT): DTAFast P8 has no battery-constant input; not needed - OEM-E9 50: Knock sensor 1 (KNK1): no free knock input on DTAFast P8 - OEM-E9 49: Knock sensor 2 (KNK2): no free knock input on DTAFast P8 - OEM-E10 1: 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 P8 has no dedicated key-on input - OEM-E9 60: Wastegate VSV (boost control): no free low_side/ls_hs/injector/hbridge on DTAFast P8 - OEM-E9 73: Fuel pressure-up VSV (FPU): no free low_side/ls_hs/injector/hbridge on DTAFast P8 - OEM-E9 74: Purge VSV (EVAP): no free low_side/ls_hs/injector/hbridge on DTAFast P8
