This is probably not a helpful post, but here are some pictures I took when assembling my megasquirt. This standalone ECU has been running my ’94 Miata since 2018 and it’s still working great. If I can solder this kit together, maybe you can too.
The assembly instructions for the kit were excellent. Everything was well-labeled in the board silkscreen and on the labeled baggies of electrical components (resistors, capacitors, diodes, etc.)
