You can use any of the harnesses...as long as you have the whole harness

I have a 93 4 cyl complete harness from front to back

89 tilt column and a 92 dash ..with a little modifying on the platic column cover around the column it can be done if you want to...

as far as the harnesses some of the connectors like to the wiper motor and the wiper switch and getting the rite cluster is were most of your problems will be, but if you get all the same stuff from the same car you will be fine

and the gauges there are a couple of different ways to make them all work .

simpilist way would be to run wires from you cluster to your senders like water and oil,tach very simple to figure out...

you can tap into the ignition switch to make all of the other stuff work

like fuel pump ,msd,ect

or if its not a street car it can be done even easier make your own harness...

if you look you can find an aftermarket harness not painless from 80 to 300 bux

but although not that hard, but time consuming splicing everything together and then you still need some of the stockharness for the end plugs to the connections. pita if you ask me
