$99.00 MSRelay-C: Assembled relay board
$85.00 MSRelayCable: Megasquirt to relay board cable

Not needed - it will take an extra 4 hours to do the wiring without the relay board.

The main reason for the relay board is it has the fuel pump relay and terminal strips - makes wiring a bit easier.

For your application - you can wire direct from the MS3.0 board. You will need a good pair of uninsulated terminal crimpers though.
