Ok. Thanks for the clarification...probably just a coincidence then and I just goofed putting the cable back in.Yes, if you only disconnected the cable from the T Case and did not mess with the speedo cluster, then you did not cause an electrical short.
The cable itself is mechanical & not affected by anything electrical. The electrical part is when you accidentally touch metal (the dash) to the backside of the amp meter. If you did not open up the dash, you are good.
