Since you guys seem to have cables and access easy access to the back of the control panel, I need to know what size the pin is that the red cable slips over on the control panel slide for the heat control? Mine slipped of the post the other day and I had to take half the dash apart to get to it. I want to put a push clip back on before it button things back up. I don't want to go thru this again if I can help it.
