I just replaced the clock on my 86 240. I didn't keep great track of my unplugging sequence and when plugging in wires, 1. I noticed a female electrical plug towards the bottom of the back between the clock and the speedo. I couldn't find a wire that will plug in there. What does that connection control? See green circle on attached photo. 2. Under the fuel/temp gage, there is a single male connection that two of wires will plug into better than the other. When I plug it it, it seems to control the OD yellow arrow. See red circle on attached photo. 3. How many things should be plugged into the back. I get the two big sets of wires, the little ones are a challenge. (there is no tac on this car. Only clock, speedo and fuel/temp). Any help is appreciated. Thanks, brian.patton@yahoo.com I just posted the photo on the photo section of the board.......couldn't seem to get it done correctly as an an attachment here.
