they are steppers so probably + - signal and brake/reverse, only the speedo uses all 4, the other gauges are slow acting enough not to need the brake/reverse.
laid out the PNRDL hole, secured the face
used a drill bit to open up some starting points. used a roto zip, definitely not the right tool. if done again I would use a small cutoff wheel.
after a lot of filing, it fits.
carved out the back of the quad to let the motors fit through
looking good
I drilled through the stepper lens to make mounting screws and got everything put together
started wiring, to the circuit board it is as simple as barrel connectors
to the stepper it is as simple as grinding the end off the barrel connector and slipping it on
titus break
I didnt get the gauges installed, but I did get an overflow tank mounted.
