Lets talk guage hook-up... help me out...

[75stepside]

ok... when i bought my '75 stepside, the previous owner had all manual guages hooked up... when i bought my new cab (from an '84) i got the complete interior wiring/fuse box. now, i also aquired a fully reconditioned tach dash cluster.

so, how do i hook these guages up? after i plug in the wiring harness plug on the back, i then have to hook up each guage individually? using sending units? where's a good place to hook up my temp, side of head?

i also, am probaby going to get a painless system... how does that complicate/simplify the above?

thanks again!
