Invisabrake compatibility with CoolTech harness on Jeep

I've got a '12 Wrangler with the aftermarket CoolTech towing harness. Is anybody using the Invisabreak with a similar setup.

I figure I can call Roadmaster tomorrow and maybe get my question answered but thought I would ask here first. I wouldn't even try to ask Cooltech since they are unresponsive to customer service inquiries.
