Feel like I'm clogging up the forum with threads but they are different subjects. The used boat I purchased has a HDS7 and HDS5 and StructureScan HD module included with cables. They were packed separate but I think I have figured out the wiring down to 3 questions remaining. 1) Would the front unit be the HDS7 (Touch Screen Gen 2 I think) or the smaller HDS5? Not sure if bigger unit goes with steering console or up front with trolling motor. It could be wired either way. 2) There is a StructureScan transducer and normal transducer in back of boat but there is also a normal transducer that was attached to their front trolling motor head. Is this required since the one on the transom shares information through the enet cabling on the StructureScan HD module. 3) They had the front unit tied into the trolling motor battery. I assumed it goes back to main battery but I can also piggyback off one of the 2 trolling motor batteries if required. It seem sensible but I will measure voltage first. Thx ahead guys.

I lost power to my fishfinder last time out fishing. I had it hooked up to the fuse panel on the console. It was pretty hard to trouble shoot on the water. So my question is is it a good idea to run the fishfinder wires direct to the battery ?
