[CA] [CA11] Replace ST8001 with p70RS control head

[hynespa]

I see in the autopilot FAQ the thread "Can the p70/p70R/p70S/p70RS Autopilot Control Heads be used with older autopilots?" that the p70RS can be used with the S3G autopilot computer.

I have two follow-up questions:

1) I would be looking to replace the ST8001 control head with a p70R control head. Where can I found the cutout dimensions for the ST8001 vs the p70RS so I know if the newer p70RS control head will fit in the [censored] that was previously cut in the dash panel for the ST8001? If it turns out the p70RS is smaller - is there any adapter piece available so that there is not a [censored] in my dash?

2) I have attached a network diagram of my current setup. As you can see I already have a D244 SeaTalk Junction. It looks like in the FAQ referenced above this junction would make the connection between the S3G computer and p70RS controller. Could I use the existing D244 junction, or would I have to add a second D244 junction? On the D229 cable that currently connects the S3G to the p70RS would I leave the red cable connected to the autopilot computer?

Thank you your help is always appreciated!
