Going to be adding (ot tapping in) to electronics....one word of advice SOLDER.<br />The corrosion that boaters experiance is terrible and allot of slip shod connections can be the source of trouble. <br /><br />No matter how tempting a "scotch lock" connection may look, it normally causes poor connections over time.<br /><br />I sand all my connections, solder then seal out the moisture.<br /><br />Good luck. Happy Thanksgiving.
A popular way to seal solder joints is with "shrink tubing", that shrinks when heated. I prefer "Liquid Electrical Tape", which is a dip-or-paint-on vinyl. Either works very well to waterproof connections. Be sure to remove any residual flux before sealing.<br /><br />Good luck, Capecliff.<br /><br />Red sky at night. . .<br />JB
Another point to consider, is using a good crimp connector (non-insulated), then solder.<br />A solder joint alone can be vulnerable to a over-heated wire, in which case, the solder can melt away.
