Topic: 1981 tachometer

ok so i got a gauge cluster from a 1981 2wd pickup. it has a tach. mine did not originally have a tach. so i think i know what wires are for the tach (the ones right above the speedo cable) but neither wire has power. so where do i get the power for one of those wires.

it should be just a plug and play thing. as long as its the one with round gauges and round plugs you shouldnt need to do any wiring.

i swapped a 81 cluster with tach into my 79 and it worked fine with no wire work

well everything plugged in right. everything works except the tach. and neither of the 2 wires above the speedo cable have power and i can't find where they go to.

just make sure its a gauge cluster from a 2WD i bought a 2WD 82 cluster and tryed puting in my 83 4x4 and it  dident work. so  it is key to mach 2WD to 4x4 and year like 79-81     82-83

Sometimes they didn't hook up the wire or even run one on the coil for the tach on certain years. You may have to run one.
