Scott-tt Posted May 31, 2015 Share Posted May 31, 2015 I have been sorting out my rev gauge on my V8 swap I have swapped in a MR2 tachometer but I'm trying to figure out which screw holes (terminals) on the back of the cluster are for 12v, ground and signal somebody will probably know, I've spent hours trying to work this out now lol. Its the three holes in the middle I just don't know which one is power and ground I know the answer is on here somewhere because I read it about 2 years now I just cant find it Thanks Scott Quote Link to comment Share on other sites More sharing options...
