If it hadn't been for the fact that there is absolutely no one that stalks an off-the-shelf triac around here. No electronic supply houses zip. I would have just ordered a triac. But I was stuck for one and the customer was due to leave for the islands so I put what is likely the exact same relay that came in the rather Troublesome queue models from Dometic had no mounting kit no white wire with red stripe to make the fourth connection and little or no clearance inside of the stowaway control fox. Had to wrap the whole thing in a giant chunk of split Loom to keep it from shorting in there and it worked. I would have preferred a $6 triac
Worked great

My boat a/c was not cycling on and off based on temperature. Easy replacement with this part and now works fine.
