I read someplace, maybe here, about putting a red warning light in the
dash which would be wired into the warning horn of the Low Oil/Overheat
horn which is on my 2000 40hp Merc. Well, could someone tell me where
this is located at and how I can get to it? If you have done this, would love
the help. Thanks.
Can anyone tell me what color wires these are? Also, is there a safe
way to test this out?

Thanks so far for all your responces!
