I am just about fiished upgrading my car, I changed over to a D1 Procharger. My problem is when I was checking the oil in the Procharger I put the dipstick into the headunit and when I pulled it out the black plastic piece on the end of the cable did not come back out. It did not get caught on anything and the cable is not fraid or anything it looks like it came un bonded from the cable. Anyone had this problem? or know how to get it out?
