I currently do not have a tach but i bought a cluster from the same year (87) firebird that does and I plan on swapping them out. How would I go about hooking up the voltage and tach guages?

Thanks for the help

just swap it out,, you'll need an oil press gauge & a temp gauge sensor (the 'idiot' light sensors will not work) to make those work right tho
