Raymarine Auothelm ST1200 mouning in Tanzer 7.5

Anyone have advice on mounting the Raymarine ST1000 autohelm on a Tanzer 7.5? There are a number of fitting adapters available to get the X,Y and Z coordinates correct.

Also, my boat has a single battery (no electric start) that runs the radio, depth/speed gauge, bilge pump, and sometime the running lights. It is connected to a good-quality solar charger. With the addition of the auothelm, is I wise to put a second battery into the system? I sail solo a fair bit, and expect the auothelm will be used a lot.

I've got the Simrad version mounted in a C&C 25, they mount the exact same way. About all I can say is be as accurate as possible with your measurements. I lashed my tiller in the centre using the cockpit winches as "adjusters" kept measuring from side to side. When I had it as good as I could get it I did the other measurements and started drilling. Mine mounts under the tiller on the drop pin holder thing. Other end is right into the seat not far infront of the transom.
I really don't know if you need two batteries, my boat came set up with a start battery and 2 12v house batteries, my motor does provide some charging, shore power the rest. I've never run low on juice, I also sail solo a lot but don't use the TP that much, usually just when raising and lowering the sails. I run about the same electronics as you but no solar, do run a gps/plotter. Next years project will be solar.
How many watts of solar are you running?
