So it's KU engine... Well, it's KV's twin, so it isn't as advanced as KV. Problem is - theese shematics I'm using is american, their engines was more advanced to comply emission laws

I don't remember, was there seperate ISV control unit or wasnt... Anyway, when ignition is turned on, there must be +12v on one wire.
Are u sure u doesn't have any additional fuses in fuse box?
