In order to utilize my existing system check wiring ( 2007 115hp Etec ) Ive heard that a resistor of 47 ohm and 5w must be used in the circuit. Is this a special resistor, or will the square ceramic ones off the internet for $ 1.something work? Is there a wiring diagram on here somewhere that Im missing. I understand that I just wire it from my purple lead for trim sender to the white/tan trim lead to close that circuit. Aqua marine was the only people Ive heard of that knew anything about this trick/money saver. I would also like to use the spare purple lead from my tach. for the switched B+ power supply. In your opinions does this sound correct? I would like to know it works before making the purchases. Thank you all Tony Fox
P.s any help in the form of wiring diagrams would be appreciated extremely!!!!!!!!!!!!
