On my 90 welcraft mercruiser 4.3 v6 the tank is in the floor there is a green wire that comes out under carpet near bilge out. My fuel gauge don't work this wire is just laying there not hooked up. Does the wire need to go to power or is it ground. Also near the right side of manifold I have a white wire with blue stripe that just zip tied up any idea where this wire goes. Has a round connector on the end of it. Motor runs an all just don't know where that white an blue striped wire supposed to go.
