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	1: read the Findings page before cutting any wire
Size of the job	62 wires · 6 connectors · 0 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).

#	Probe A	Probe B	Expect	Why
1	ME442-C1-15	ME442-C1-10	open (OL)	+12 V supply must not touch power ground
2	ME442-C1-15	ME442-C1-52	open (OL)	+12 V supply must not touch sensor ground
3	ME442-C1-45	ME442-C1-52	open (OL)	5 V sensor reference must not touch sensor ground
4	ME442-C1-10	ME442-C1-45	open (OL)	power ground must not touch 5 V sensor reference
5	ME442-C1-15	ME442-C1-45	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: - Trigger pattern for Toyota 2JZ not found in the ECU's docs (Trigger-pattern list is only inside MEITE software, not published online) 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): Motorsport Electronics ME442 has no battery-constant input; not needed - 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); Motorsport Electronics ME442 has no dedicated key-on input
