Can I do this? Yes I can with Gregs help. I just wanted to post a follow up on this post that I made. I first of all would like to thank Mr. Greg Walters for taking his time to email instructions to help me with this. The information Greg sent me was perfect, easy to read and understand. I was able to cut the cables and solder them back. I was careful not to tear the foil wrapping and I re wrapped the wire later with the foil and I also used shrink tubing on the wires to isolate them from the others. Then used bigger shrink tubing to seal the main wire and taped the wire to make sure no water could get in. If it had not been for Greg's instructions I would never had figured this out. My sonars are working perfectly now using it's internal GPS to support the other that needed a external GPS antenna. We are very fortunate to have Mr. Greg walters at Humminbird here on crappie.com. Thanks for helping
