i just installed '97 CVPI cluster in my '96,(had to swap out all the guages, long story...) and would like to do this mod, however my '96 cluster doesn't have a resistor like dRock's does (his circuit is yellow, both mine are red...), nor does it have one on the back of the gauge. does that matter? will it still work using my '96 gauge? i'm thinking there may have been a difference, as dRock's car is an LS, and mine's a GS....
