Hey all, I created a thread only a few hours ago in Audio/Visual about my after market head unit possibly causing problems, but it might not be that. I have a speed sensor issue. It seems that between the speed sensor at the wheels and gearbox there is a problem, however it could be related to my GPS Plot Point. Apparently this is fitted in all premo sound fords but isn't always connected, and if this is spliced into for power, or completely disconnected, it can cause speed sensor issues. The
