here you go dude

The front of the instrument cluster easily pops off, and then its just 3 screws (at least for this cluster) to remove the tach.


Here is the screw-type potentiometer in question


Another shot


That should do it. You'll have to fine tune it, but which direction, I dunno. According to the other thread, 1/8 to 1/4 of a turn should suffice. Get yourself a tuneup tach and dial it in haha

And on a side note, this instrument cluster of mine is cherry...


Though you can't tell so well, the needles are BRIGHT orange haha. Not faded whatsoever. And yes, that is less than 83k miles on it. Damn shame, it came from a fully loaded SR5 truck in mint condition, some 16 year old rolled it...
