Hi, just got under my VT V6 to see if I'm able to remove the starter motor myself. I could remove two vertical bolts on the bottom and one horizontal bolt on the top of it. But I can't figure out how to disconnect the wires. Should I use 13mm ring spanner to undo "30" B+ Terminal and pull off "50" Terminal? Where can I get it? From top of the engine bay rather than under the car?
