GRT Servo Pre Wiring?

I want to install the GRT servo brackets and wiring for later installation of the servos. I can?t seem to find the wire size and breaker size required on the GRT website. Does anyone know what these are? Also are there any other consideration to make installation easier later? This is for a 7.
Thanks

See GRT website>Support>Manuals & Software>Autopilot.

Ref page 16 & 17 of the GRT Autopilot Installation Manual. Current version is Rev B, 18July2018.

I installed these in an RV-8 per the manual. Straightforward, no issues.
