Thanks for the input guys. Unfortunately, my microwave is in the island, near the floor, that is a no-go. The two wires I saw was a paired wire, white/red. The red was twice the size as the white. I do have a test light, I will give it a look next time we are out. I am not worried about grease and what not, it will go in the roof/ceiling in the 14inch x 14inch existing hole. I am looking at FantasticFan 6600R, so the wife will actually be able to use it. Once done, yes, the silly alarm will quite going off every time we cook. Boggles my mind why I have a vented hood that is not actually vented to the outside....yes, I appreciate not having another hole in the trailer and not having to deal with critters and cold drafty air, but....
