The AP44 kit you ordered doesn't look like it has any hoses or cables to connect to the computer. You will need a couple of T's as well. You can T off at the helm or the Electric pump. It is a good idea to use a clear hose for the return line so you can always see if you have air in the system.
Besides the hoses that you need for the hydraulic steering you need these 3 in the picture below to connect the AP pump to the system. As you can see these are fairly short, the length will depend on how close to the helm you can fit the pump. Note the clear hose if for the return. I also used fitted hoses, you may use compression fittings, I prefer factory fitted.
The other pic shows the brass T'S you will need.
In the last picture you can see where I located mine on my 228 , probably irrelevant to you . I made a S/S bracket and used some rubber under it so I don't get any vibrations.
Before you fit anything on, lie everything on the ground or bench and dummy fit everything, no need to actually screw anything together.
"You can run the hoses through your cable boot in the splashwell and do away with the added cost and possible leak points of bulkhead fittings"
Good advice for your boat, if they fit in the cable boot. You will save some $$ as well.
