On a ralleye dash the limiter is part of the fuel gauge and you either replace the fuel gauge or find the instructions on by passing it with a regular limiter. That is why I suggested checking the fuses and sending unit wire with a test light first. You can test either the temp gauge or oil pressure gauge wire which ever if easiest to get to. Either should blink if the limiter is good. You could also check the screws holding the instrument cluster to the dash because they act as ground.
