Manual transmission, INsTALL(jacking it up)

hmm, have to read up on that part in my haynes. never had a manual suggest different weight oils and change intervals like that. normally since theres no combustion cycle and deposits to soak into the oil, it doesnt need changing. i guess due to initial wear you could have a small amount of metal particulate, but not enough to cause a problem the magnetic drain plug cant contain. but whatever the manual says

as for the wires, yep that sounds right. makes a constant circtuit so the car thinks its in neutral and will idle when off throttle or while sitting.
