What you need
- ECU

- Multimeter
- Small gator clips
- Wire
- Small gauge connectors
- ECU & OBD harness (optional, but very handy)
Power source
Set up your 12v+ DC power source. Make sure you have constant and stable power! The PS-3KX is nice and inexpensive. An ATX (computer) power supply (12v) is also a popular choice.
Wiring
