I am a greenhorn to the jet boat family, hi how yall doin? I bought a 1977' Taylor SS Jet boat about 1 year ago and I just decided to restore this bad boy. So I have already started to take off all chrome, gauges, rotted floor and stringers, I am about to replace the floor and I started to take out the gauges and figured out they are the manufactured wires with a plug that runs towards the steering wheel and I have the wiring harness that runs to the engine but the plugs on the wiring harness and the gauges don't match and I'm missing the key switch idk if they both plug up on both sides of the key switch or what. Any info on this greatly appreciated, thanks.
