I put in a new instrument panel (one from a 93 cherokee lol) and everything works but the temp. which rests at 100 and the oil pressure which pegs....I'm not sure if I should be worried about the oil pressure because my idiot light that i used to have never came on so i doubt my pressure is actually that high, any ideas?

 

you'll need a temp sender for a gauge (goes at back of engine) p/n 56027012 and an oil pressure sender for a gauge p/n 56026719.... look here.... http://jeepin.com/features/gaugeswap
