I've got one of the Fell Marine MOB+ units on order. Unfortunately they are back ordered until June. I would like to have everything I need to get it hooked up when it gets here.

I've been having trouble figuring out definitively if I need to use the double throw relay on my boat. It looks like the factory kill switch has 4 wires coming from it, so I am pretty sure I need the relay to hook it up. Unfortunately the documentation doesn't cover twin Yamaha jet boats. I assume the Fell relay is the way to go? Would you recommend some other generic relay instead?

Is there any wisdom out there about the best place to mount this on the FSH console? It seems like you would want it in plain sight. I'd rather not put it up on the windshield deck. It seems like the horizontal area right over the steering wheel might be a good choice. Any thoughts?

I also have one on order and wondering if someone with a FSH can take a few photos of how they wired the MOB and additional engine harness?
