HARNESS LAYOUT — Engine Control Harness and Engine Harness No. 2 (Cont'd) — Connector Index (Supplement-VII)
EL-7100component photoGasoline engine harness connector index. Note F62 ID conflict between ECM (passenger compartment) and IACV-ACC valve (engine control harness). CVT adds dedicated sub-harness (F300/F302) + pulley speed sensors (E140/E141) + TCM at F46.

NOTE
Gasoline engine harness connector index. Most ECCS sensors and actuators have dedicated F-prefix connectors:
• Air/fuel: F1 MAF, F2 TPS, F3-F7 injectors, F10/F11 coolant/water temp, F13 O2 front, F56 O2 rear
• Ignition: F49-F52 spark plugs
• Position: F54 camshaft (PHASE), F58 crankshaft (POS), F31 VSS
• Idle: F62 IACV-ACC, F53 EVAP solenoid
• ECM: F62 connector to ECM, F57/F58/F59 inlines to main harness
• CVT-only: F46 TCM, F55→F300 sub-harness, E140/E141 pulley speed sensors, F302 control valve
Note 'IACV-ACC valve' on F62 entry — different from F62 ECM connector. Two different uses of F62 in the source. The connector index entries are: F62 = ECM (passenger compartment side); F62 = IACV-ACC valve (engine control harness side). These are two separate connectors with the same numeric ID — flag for cross-reference disambiguation.
WARNING
Connector ID F62 used twice in source for different components (ECM vs IACV-ACC valve). When servicing, identify which harness the connector belongs to (engine control vs passenger compartment) to avoid confusion.
