Alright guys Ive been searching arround for weeks now, and yeah I went on ahead and looked, sad enough I see that everyone says 10K resistor ..... thats great I got tons of 10K resistors!! but I don;t know how many watts.. I already tried the FSM but i found nothing. I tried a 10K 10 watt. and it basically made my tach go from 2K to dead. so yeah. how manny watts do I get the Resistor for so I can get my damn cluster working. thanks in advance.

Has anyone bought a modified tach (and measured it) or successfully soldered in a resistor?I was going to try a variable resistor. Is their a write up some where?

On the back of the s13 cluster is a potentiometer, which is a variable resistor, you can play with it to get it to work with the Rb signal. I havent done it yet as im still waiting on a motor so, i cant say for sure if it allows this much adjustment, but i hear it does.

that is only for S14. and the signal will still be of by a bit. adding the ressstor is the most accurate.
