the mods look done correctly.
one the harness, make sure the brown and white/green wire labeled ignitor goes back to these spots:

If they do, make sure the white/green wire that's labled pin 31, acutally goes back to pin 31 on the db37 side of the harness. If it doesn't, check to see if pin 31 is acutally going to position 1V on the harness connector labled Clutch.

okay. i've never really dealt with wiring diagrams and pinouts but....
as far as i can tell, the white/green wire in 1G on the car side of the harness goes to pin 26 on the MS side. the brown wire in 1H goes to pin 21. the green/white wire labeled clutch in 1V goes to pin 28.
this is from my dumb *** looking at the picture you posted here, and this pic in your MS tutorial
