Hey RP,
I'm pissed I forgot my camera, so I could tell the story easier, but I will need to struggle with my bad typing.
The C.P. will need to be moved down so that the clutch lever will move freely and to allow clearance for the gray wheel pilot bracket. Here is the trick; it is glued with sealant so first remove the (8) front and unscrew the (4) screws that hold it to the pedestal. Then screw the front back on. While using a long thin spatula rock the C.P carefully back and forth while pushing the spatula into the joint. Be patient it will eventually release. If you try to do this with out the front installed you will probably break it. The front is providing stiffness. You will not need to cut the tube that the wires run in, when you move the C.P. down ~2" it will just protrude further into the C.P., no problem. Re-drill the holes in the back of the C.P. to match the existing holes in the pedestal, or drill new ones, while paying attention the square-ness, there is very little room between the wheel and the C.P.
I still needed to cut ~.5" off the end of the clutch lever to provide clearance.
Ya just kinda have to fudge this thing in there.
On my 310 there is no hole drilled from the aft cabin up into the starboard pedestal guard tube, so I used a fish tape and was able to get the motor wire down the C.P. tube after first running it through the hole I drilled in the back of the C.P.
I chose this location for the computer based on wire access. You can remove the little cubby under the stove and that will provide access to feed wires through the holes drilled in the fiberglass just to the right of the computer.
I have some reservations about where I mounted the FluxGate compass, under the sink. It's not the sink I'm worried about it is the possibility of permanent magnets in the water and sump pump motors within proximity. I really need to get a compass and see if it work accurately there. I may end up having to move it to where Paul' mounted his.
I mounted the RPS just behind the water heater, the way Maine Sail mounted his, but I created my own bracket. I needed to shorten the steering stop cables to ensure I did not drive the sensor beyond it's travel limit.
I will try to remember to take pictures this coming weekend when we launch.
