View Full Version : Yellow wire at key switch,

05-12-2007, 08:49 AM
On the back of my key switch I have a yellow wire that is not attached but 'hanging around' in the vicinity. Can anyone tell me what its for and where it should be attached to. It's an 89' Tristar with a 351 Indmar.

someone might have ran the yellow memory wire from the radio to the key since the key always has power. When you turn off the radio does it lose its my memory??

I don't even know if the radio works
