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 | 82 wires · 35 connectors · 12 part lines |
| Tools | Crimp and extraction tools for each terminal family (see Connectors) · wire strippers · multimeter · heat gun + heat-shrink |
| 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).

Notes
Engine harness for Toyota 2JZ-GTE, generated by engine_build() on 2026-10-08. Draft: engine-side plugs are named by function; meter each pin at the component, and confirm cylinder numbering and firing order, before crimping. Power layer to finish: size main fuse F1 for the total load, and feed NEW-IGN from the ignition switch (key-on +12 V). Pigtails: 0 plug(s) as ready-made pigtails; no pigtail sourced yet for CKP, CMP1, CMP2, COIL1, COIL2, COIL3, COIL4, COIL5, COIL6, ECT, IAT, INJ1, INJ2, INJ3, INJ4, INJ5, INJ6, ISC, KS1, KS2, MAP, O2, TPS, WGV (loose mating plug in the parts list). Left out (optional, nothing on this ECU to wire them to): WBO (LSU 4.9).
