Jeff,

When you get to Camping World they should have a kit that will convert your seperate turn and stop lights to work as combined units on your trailer, they might even be able to wire it up for you if their shop is open. The kit is very simple to install if they can't - instructions are fairly detailed. it's called 'Universal Towed Car Wiring Kit' and is usually a stock item. On the brake controller - if your coach doesn't have one the Prodigy unit is one of the best on the market (most expensive too) and they should also have that in stock. Your trailer wire cable probably has a 7 pin connector rather than 9
