I swapped a Chevy 4.3 vortec into my '94 wrangler and would like to know if there is anywhere I can get a new instrument panel that will work with the new stuff.  I bought an after market tach & mounted it on the steering column and new temp gauge but they look kinda hokey.  Any ideas??

thanks!

Gauges
In 1996, coupled with the advent of the OBD-II standard, Jeep also introduced a fully electronic gauge cluster. The six gauges have one integrated microprocessor that receives a multiplexed signal from the PCM. This digital signal cannot be generated without the Jeep computer. There are two ways to get around this: the first and best is to upgrade the Jeep cluster to an aftermarket set that is fully GM compatible. The fuel level meter should be Chrysler compatible since you will be using the signal from the factory fuel sender. In the end, this may be a better method due to the accuracy, adjustability (especially important for the speedometer on Jeeps with varying tire sizes and axle ratios) and custom look.

The second way to circumvent this challenge is to run the Jeep computer (ECM) in tandem with the GM powertrain computer. This consists of applying source voltage to the Jeep unit and then feeding the varying (oil pressure, water temp, voltage, etc.) signals into it to be processed and multiplexed to the original gauge panel. Currently, there is no way to get around the Tach difference between the four, six and eight cylinder applications.  

dakota digital offers digital gauges and aftermarket sending units for just about anything anymore...  

go through Howell.com and get a custom wire harness and then just put on any tachs custom to your jeep.  That is what I did and I fabbed a back panel for all the new tachs.  it came out well and works just as good.
