454 Mag Mpi Horizon stand starting.
 

Hello all,
First time thread.
I have just spent the last 4 months
Pulling down and completely rebuilding 2 x 454 mag mpi Horizon motors. I would like to start the motors on the stands i have built, before installing back into the boat. So i am after someone experienced in this area with some help on what neefs to be connected to start them on stands.
I am aware i need
F​​​​​​uel
Battery
Water ect...
But as the second part of the harness is still in boat, some guidance here on what needs to be connected would be greatly appreciated.
Motors from Searay 34 Dancer 2000 model
Thanks in advance
Aaron....
