Wiper motor replacement

Hi all.
So this weekend I will be replacing the vacuum wiper motor with a replacement vacuum wiper motor. Mine is missing all the parts to connect the cable to it as you can see in the picture. Attachment 27415
It definitely works though. When I pull on the coordinator by hand the wipers move smoothly.
Anything I should be looking out for when I remove this from the fire wall? I don't want to mess with all the cables and parts behind the firewall. Is it just unbolt it and bolt a new one in. I saw some posts saying not to move certain things or it becomes a real nightmare. Any guidence will be appreciated.

On a side note related to the wipers. After spending a small fortune to replace the wiper fluid pump and getting it to work, when i crawled under the dash to hook in the water lines the water tube bolts are not there (go figure). Who has this part? Also, any photos on the nozzles, I'm sure I'm missing that too.

Thanks all
