I have lost the little round cover that screws onto the cockpit socket, where you plug the pilot in.
SIMRAD and others can't help. Does anyone have an old SIMRAD tiller pilot and be prepared to give/sell me the cover.
Have you tried every plastic soft drink bottle cap known to mankind ?
No I haven't, only a milk bottle top. But I will now!
I have just fitted a new TP32 autopilot alongside a Raymarine St2000 and the screw caps are interchangeable.
If your TP32 socket matches the one on the left in the pics below, sourcing a Raymarine cap may be an option.


Well if it's the same as a Raymarine then it's a "Bulgin" type plug.
Plenty of options available online or even Jaycar.

Yep, that is it.
