Hello, I have a Jon Boat I picked up some years back and am getting it ready to do some fishing. It is prewired with a Transducer mounted on the transom and has the power cable also run. Both of the plugs are 2 pin round plugs. 1 power and 1 tranducer. I came across a Hummingbird TCR ID 1 head unit this week. This thing is hardly used and looks brand new. When I looked at it I new it had differant plugs on it but for 5 bucks I could not pass it up. I was able to power it up with a makeshift plug and it worked great. It went into the demo mode and was able to play around with it. There a 3 other 2 pin plugs lined up next to each other. From what I have been able to find out that 1 is for the transducer, 1 is for the speed function, and the other is for the temp. My first question is which one is for which. The plugs are all the same with a notch in the same spot on all 3. There is no markings on the rear cover at all. Which one is for the tranducer? The other question is would it work with the transducer I have on the boat. Its no problem to make an adapter but I just need to know what one it plugs into. I know the tranducer that is on the boat is from the mid 80's. Any suggestion or thoughts. Sorry for the long post.
