Just want to share this info in case it helps someone else in the future
My new to me 2011 2350 PC had the the pump and hose removed by a previous owner and the connection to sewer capped off. I determined that it originally had the sanicon 70428 direct twist on system from the factory. This unit as of now is obsolete to purchase as a kit from anywhere online. Reaching out to Thetford confirmed this and they agreed that the sanicon trubo 400s would be the correct new model to go with. The 400s comes with a small switched control box that i simply put in series with the pump switch in the dump station panel and zip tied up in the undercarriage. I also opted to get a quick disconnect wiring connector to install inline with the final pump wiring in case there ever becomes an issue and i need to remove it quickly if there ever becomes a problem while on a trip. Also installed an abrasion jacket to the hose to protect it as ive read that can be an issue. The 2 main issues of note are as follows.
1. The turbo 400 is shorter and larger diameter than the original so the suspension bracket that comes with it cannot land in the original location and ive yet to figure out the best way to attach that part. It seems very firmly secured with the twist on flange as is.
2. The hose is larger diameter than the originall so the factory storage clips had to be replaced and the access hole to the bay enlarged. The rubber boat oar clips i found on Amazon are a perfect fit and seem to hold nicely even without securing the rubbet strap
