Hi everyone from Colorado! Just obtained a 93 Eagle Series 280 Motorhome and I will be needing information upon occasion. This unit did not come with a receiver on the rear so I can tow my sons medical equipment around, but thru some research I think that I have found a unit that will bolt on coming next week. First question, what wiring is the best to use so I can plug and play? There appears to be two plug in's coming thru the frame rail and a white wire with a crimped circle on it. One plug is black and the other is brown. Does anybody know what these wire plug in's are for? And if they are for trailer wiring, what part# and manufacturer should I look for. Hoping to get an answer soon, as now that the weather is taking a different look, we would like to have a weekend outing soon.
