Jargon Posted October 7, 2014 Share Posted October 7, 2014 This can probably be answered with a "yes" or "no." My MJ has the light-only-style gauge cluster and I don't like it. I have the chance to pick up the 'preferred' style gauge cluster, but I don't know if the swap is straightforward or not. Can I simply pull out the old style and install the new one without any special modifications? This is the one I have: Image Not Found And this is the one I want: Image Not Found I only ask because I don't want to start this swap and get half-way through and realize I've goofed. Any input is really appreciated. Thanks. Link to comment Share on other sites More sharing options...
88ComancheMitch Posted October 7, 2014 Share Posted October 7, 2014 Yes, you should be able to just swap them...but I'd waaaaaay rather have one with a small fuel gauge and a tach. EDIT: What year truck, and what year is the cluster out of? Link to comment Share on other sites More sharing options...
Eagle Posted October 7, 2014 Share Posted October 7, 2014 In addition to swapping the cluster, you will need to change the oil pressure sender and the engine temperature sender. Link to comment Share on other sites More sharing options...
thejim42 Posted October 8, 2014 Share Posted October 8, 2014 Easy swap. I did it on my 88 Link to comment Share on other sites More sharing options...
Dadinator Posted October 8, 2014 Share Posted October 8, 2014 I have never seen that cluster you are switching to. But as said before, it will swap with only the addition of the sending units needing changed. They are very easy to change as well. Check my build thread if you need details. Easy as pie.

thejim42 Posted October 8, 2014 Share Posted October 8, 2014 Make sure the back of the new cluster is the same color as the original. Blue swaps with blue, white swaps with white. Link to comment Share on other sites More sharing options...

EDIT: What year truck, and what year is the cluster out of? I would definitely rather have the one with the tach as well, but I assumed it would be a more complicated swap, and I'm not sure how deep I want to get involved in this right now. Since there currently isn't a tach, I was assuming it would be extras wiring/parts to get it set up to run a tach. If that is straigtforward as well, I would for sure do that instead. My MJ is a 1990 and the cluster I am getting is from a 1989. Make sure the back of the new cluster is the same color as the original. Blue swaps with blue, white swaps with white. I don't yet know what the colors on the back are, but I'll make sure they're the same. Thanks. But as said before, it will swap with only the addition of the sending units needing changed.

thejim42 Posted October 8, 2014 Share Posted October 8, 2014 Tach is plug and play. Nothing extra to ad a tach. I did it my 88 a year ago. Couldn't be happier Link to comment Share on other sites More sharing options...
Eagle Posted October 8, 2014 Share Posted October 8, 2014 Tach is plug and play Literally. There is NO wiring necessary -- it's already there. The speedometers in both of your photos are the "old" style, which probably uses a metal clip and a screw to hold the cable to the speedometer head. The tachometers in that style don't have any way to calibrate between 4-cylinder and 6-cylinder, so if you buy one, be sure it came from a vehicle with the same number of cylinders as yours.

That's great news. I assumed it would be difficult so I didn't even bother looking into it. Okay, so I'll get a cluster with a tach instead; luckily there are a few on Craigslist right now. I did see in another thread (just now) detailing that some tachs can be calibrated to fit either 4-cylinder or 6-cylinder, but I'll stick with getting a cluster that came from a 2.5L to make the swap more idiot-proof. Thanks guys :) . Link to comment Share on other sites More sharing options...

I thought there was a POT somewhere in the tach, It may have been a different year but... http://comancheclub.com/topic/29455-potentiometer-and-gas-gauge-questions/?hl=tach Link to comment Share on other sites More sharing options...
