Will these work??? '03 in a '89

[60 Biscayne]

How about the tach / speedometer / gauges.....
Will the ones in my '89 Wrangler work with the new 2003 engine?
I was figuring on changing the Oil & Temp gauges over to mechanical ones but what about the rest of the stuff will all that have to go also??????? if so, do I have to go with aftermarket stuff or is there Jeep stuff that will work?
I knew I should have bought that 2004 complete dash with harness etc......
I thought $300+ was too much but now it's looking like a bargain.
Thanks, Jim

If all you're swapping is the engine, everything else should work. Your speedo is mechanical and works off the transfer case tailhousing, which isn't changing.

	Transfer Case Mounted behind and driven by the vehicle transmission, the transfer case transmits power to the front and rear driveshafts in 4WD Jeep vehicles and offers high and low range.

You'll have to figureout all the wiring to splice to the old gauges. I went to mech cause it was easier...plus i'm lazy..And use the old sending units for the old gauges.
