I would like a photo from the inside of the 997 head unit.
Showing the wire colors of the 7 pin transducer connections.
I modified my unit years ago with a heavy duty connector due to the original connector failing.
Two wires have come loose in the mean time and I need to figure out the original connections.
For clarity a photo with the unit opened up looking at the 7 pin xducer socket.
Many thanks !!
