Can you help my please I changed light on my Opel Ascona C 1.3 L 82 model year those are tail light replaced with new'r version how ever the bulb holder are the same on old model and new. Im cinde of experiancing back charg. Left side is ok but the right side bouth tail light and blinker light are working together. And I expiriace electrical shock when tuching chassis. My engin self acelerate when my light are one ore when I use blinkers. The engin refuse to stop when blinkers working. And oddly my acelerator cabel on the carburetor for some reason contract the cabel when close to metalic parts the engin self acelerate to full trothel when I remove metalic air filter it stops doing the self aceleration. Any advice what culd that by? Relay problems? Shorts ? How can I bypass this problems? Im confuse why some centrain parts on the bulb holder habe some thing similar like comon ground ore neutral plate why are all bulbs share grounding? Ore did I chose wrong bulbs? Its anoying realy . Even my alternator is puting out 15v and its climing when acelerating. Im not shure my self what is hapening Im not shure if corosion on grounding culd do that staff ore not. I did fumel with the left and right side dandels for blinkers and wish washer motor did not work so I did clean out corosion on that small water container pump . Thats all I did nothing ells. So Im not shure if my relay is failing for blinker ? Im preaty much confused .

It took you 20 minutes to make me struggle to understand that accent, to only tell me I need a new circuitboard and pin assembly. Good gracious.
