Looked this information up on the Big Stuff website

The wire colors are different from MSD to Big Stuff for the Crank Trigger Pickup Sensor

The MSD purple wire should be hooked to the Big Stuff Black wire
The MSD Green wire should be hooked to the Big Stuff Red wire

Also there is a ground wire from the Big Stuff Harness with a loop terminal , it needs to be attached directly to the engine block . There should be a very good ground wire going from the battery to the block .

Special notice , Damage could occur to the controller if there is battery voltage to the harness, and the connectors are removed from the controller . TURN OFF the master disconnect switch before the connectors are removed or connected to the Big Stuff Controller .

If you can communicate with the controller with your laptop , you can set up a "dash board" that can let you add a tach signal . If you have no signal , then it will never start .

Good Luck !
