I have a 1982 Evinrude 9.9 with electric start and alternator. The push button to start the motor is located on the left side of the motor hidden in the mounting base which is the typical location for this engine. What I would like to do is move that switch to the dash by the steering wheel. I was going to splice the wires and match the wire gauges and just lengthen the wires so the switch makes it to the dash. However, I'm a little concerned splicing the wires due to the fact that two of the three wires that connect to the switch look like heavy 10 gauge wires. Can I do this, and am I going to have trouble with any electrical interference with my depth finder located on my dash??
