I'm guessing the reason the link doesn't work is because it resides on your computer rather than on a file hosting site.Right. I tried to post a link to the schematic which obviously didn't work. I'm an idiot with that sort of thing. I wish someone would show me how to do it.
What do you mean 'reverse+ or-' ?
Do you want batt+ for an acc lead?
If all else fails see if your dealer service mgr. will let you look at their manual. Mine will!
