New Ignition Module, Wiring Question.

Hello all, a quick summary. I'm installing a automatic vent damper on my 37 year old boiler that never had one, though it has a plug for one on the old Honeywell S86F Ignition Module. The old S86F isn't playing nice with the vent damper (it works perfect on a bench).

Long story short I am installing a new Honeywell 8610U ignition module. There are a few differences and I'm hoping you can check my diagrams before I install it. The 24V/24V-GND doesn't quite match up and the from-to literature is a bit confusing.

Oh....and I'm adding a C wire as I'll also be installing a new thermostat that requires it. Let me know what you think!
