I just bought a 99 efi 150 from a board sponsor to replace the 79 v6 blackmax on my boat.
I've got the 79 off boat. Only cable was a large diameter cable with 9 pin plug at the power head.
Am I good to just hook the cable into the 99? What other wires are coming from the engine? Trim and water temp separate from the 9 pin?
I have got a manual on order...so hoping it's all going to be illustrated.
