ok i need to adjust the timing, sounds simple enough. Reading the book im supposed to unplug the single wire connector located immediately above the harness connector.......Dont see/cant find it? have a 6 wire plug going to the module on side of dist. that same harness about an inch or so back has 2 yellow wires going into a connector that isnt plugged into any thing it has a grey plug on the end of it, but thats all i see, what am I doing wrong?
