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	proposal · not yet verified: nobody has reported building and running this harness
Open errors	none
Size of the job	64 wires · 7 connectors · 4 part lines
Tools	715131-1 · wire strippers · multimeter · heat gun + heat-shrink
Terminals	316836-1
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	ME360-C1-15	ME360-C1-10	open (OL)	+12 V supply must not touch power ground
2	ME360-C1-15	ME360-C1-52	open (OL)	+12 V supply must not touch sensor ground
3	ME360-C1-10	ME360-C1-14	open (OL)	power ground must not touch +12 V supply
4	ME360-C1-10	ME360-C1-45	open (OL)	power ground must not touch 5 V sensor reference
5	ME360-C1-10	ME360-C1-46	open (OL)	power ground must not touch 5 V sensor reference
6	ME360-C1-10	ME360-C1-76	open (OL)	power ground must not touch 5 V sensor reference
7	ME360-C1-14	ME360-C1-76	open (OL)	+12 V supply must not touch 5 V sensor reference
8	ME360-C1-15	ME360-C1-45	open (OL)	+12 V supply must not touch 5 V sensor reference

10	ME360-C1-15	ME360-C1-76	open (OL)	+12 V supply must not touch 5 V sensor reference
11	ME360-C1-45	ME360-C1-14	open (OL)	5 V sensor reference must not touch +12 V supply
12	ME360-C1-46	ME360-C1-14	open (OL)	5 V sensor reference must not touch +12 V supply
13	ME360-C1-52	ME360-C1-14	open (OL)	sensor ground must not touch +12 V supply
14	ME360-C1-52	ME360-C1-45	open (OL)	sensor ground must not touch 5 V sensor reference
15	ME360-C1-52	ME360-C1-46	open (OL)	sensor ground must not touch 5 V sensor reference
16	ME360-C1-52	ME360-C1-76	open (OL)	sensor ground must not touch 5 V sensor reference

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

Auto-mapped by auto_map() from the library pin data on 2026-10-09. Review every wire against both manuals before building. Not wired: - OEM-E 9: Ignition switch signal (IG1): key-on 12 V sense — optional in a swap (the main relay is energized from keyed 12 V, not from this pin); Motorsport Electronics ME360 has no dedicated key-on input - OEM-E 31: Malfunction indicator lamp (MIL): no free low_side/ls_hs/injector/hbridge on Motorsport Electronics ME360 - OEM-E 14: Fuel tank pressure sensor (FTP): no free analog_0_5 on Motorsport Electronics ME360 - OEM-E 15: Electrical load detector (ELD): no free analog_0_5 on Motorsport Electronics ME360 - OEM-E 23: K-line (diagnostic): no free k_line on Motorsport Electronics ME360 - OEM-E 24: Multiplex communication (SEFMJ): no free k_line on Motorsport Electronics ME360 - OEM-E 27: Immobilizer code (IMOCD): not classified in the library; wire by hand - OEM-E 29: Service check signal (SCS): not classified in the library; wire by hand - OEM-E 30: Write enable signal (WEN): not classified in the library; wire by hand
