I’m considering the simple RTE Replacement to fix the 5v problem for my fuel and temp gauges. Looking at the service manual, the cluster removal is quite involved. I expected simpler. Has anyone swapped their 5v limiter for the RTE Replacement in my style car (same type cluster). I know the instructions for the RTE Replacement say cluster removal is optional, but maybe not in my specific model. Any advice? I hate to take the whole thing apart.
