I bought a pre-built MegaSquirt ECU, what else do I need?
You will also need a wiring harness, a USB-serial adapter (for MS1 and MS2), and possibly an alternator voltage regulator. Many complete MegaSquirt packages from SymTech Labs already include these things.
You will also need a little spare vacuum hose, standard electrical tools (wire cutters/strippers, etc.), solder or crimp connectors, and heat shrink tubing or electrical tape.
