tach help????
What year S10 and what motor originally. You can always do what I did, find a factory S10 cluster for the same year (or years) that has a tach and speedo. Mine is a 1994 which I thought would be kinda difficult...but suprisingly it took about 5 mins of ebaying and there it was....and now works great and looks great.
Then in that case it is so very easy to just buy a 1995-1997 cluster that has a tach out of a 5speed truck. They are plentiful...the wiring is actually already there for the tach...all you do is tie into the white wire that deadends in your plug on the dash with the one from the LS1 harness...and as long as the computer was programed right...your tach reads perfect that easily.
