Eagle Posted December 12, 2015 Share Posted December 12, 2015 The easiest way is to buy a Chief or Limited instrument cluster with the tach, and just swap the clusters. The wiring is already there. Since you have a Pioneer, your should already have gauges rather than idiot lights, so you wouldn't have to change any sensors. Link to comment Share on other sites More sharing options...
Pete M Posted December 13, 2015 Share Posted December 13, 2015 clusters are grouped 84-86, 87-90 and 91-96. 84-86 and 87-90 can be converted back and forth with some minor mods. the tach may not be accurate if it came from a rig with the other size engine (if it came from a 4banger, it'll still read 1 rpm per 4 ignitions), but most can be adjusted to work right again.

thejim42 Posted December 14, 2015 Share Posted December 14, 2015 just swap in a full cluster from a cherokee or comanche with the same engine and same year group. ive done this on all 3 of my mjs. if you have idiot lights you have to swap out the sending units. if you have guages already just swap the cluster.
