I have no spark on plugs 2/3 and am unsure of the wiring of my MSnSE board.

I have followed the plans and wired my second VB921 to:

Bottom of link wire that has replaced R43
Top of R29 via 330R in proto area
To SPR4 then a wire from that to pin 6

I am using a relay board and note that pin 6 is connected to ground at the relay board.

Have I got this correct?

Regards
Steve

Solved the problem, had the relay board wired incorrectly, donut.
