This guide is a mounting drawing for single connector Elite ECUs, showing the hole pattern and case dimensions so you can plan brackets or drill a panel before the ECU is in hand. Dual connector units have their own drawing in the dual connector mounting guide.
What we check before drilling:
- Location: a dry spot inside the cabin, away from exhaust heat and direct water, where the harness reaches the engine bay without being stretched.
- Fasteners: Haltech's mounting devices page calls for M4 machine bolts with no more than 4 mm of thread entering the ECU base. Longer bolts can damage the case.
- Connector access: room to plug and unplug the connector and reach the USB port for tuning.
- Vibration: a solid mount so the ECU and harness can't rattle.
