I had a short in my wiring harness. I thought it was the 10 pin connector plug on the engine side; so i cut the connector off. I later determined the short was on the boat side of the harness. I now want to reconnect the motor side 10 pin connector. If I use waterproof connectors with solder and adhesive shrink wrap, will that type of connection suffice. A new motor side harness is 400 dollars. Expensive mistake. A boat mechanic said if i do it that way I could damage the computer. Any help please.
