Installing an Auto Vent Damper on an older boiler...

Hello everyone.  I plan on installing an automatic vent damper on my 37 year old Peerless gas fired boiler.  

I'm going to order a Field Controls damper and universal conduit kit.  I thought I was going to have to get fancy with the wiring...but it looks like I have a vent damper plug in my junction box!!!  It's the one on the top left in the picture below.

Any chance one of the adapters in the universal conduit kit will fit it?  That would be great if it does....it would truly be plug and play.  The wiring manual states a bunch of boiler manufacturers and also lists "Honeywell Ignition Module".

    Its likely it will plug right in with the adaptors. We regularly add stack dampers to larger Peerless 64 models and they are plug and play using the Weil McLain harnesses on Supply House.com.
