HO speedometer in Renix cluster

[DirtyComanche]

Is it possible to put the HO electronic speedometer in the Renix cluster, or put the other Renix gauges in a HO cluster, in order to make a hybrid cluster that will work with the Renix sending units (temperature and fuel level) but allow you to run an electronic speedo? 

 

Obviously you would need to at least add a few wires to the chassis side of the harness, plus if using the Renix cluster you would either need the HO circuit board for it or to add those wires to the cluster.  I'm not sure if the pin location is similar on the plugs, or if you could adapt/splice to make it work.

 

Is this anything that anyone has ever tried?

if you cut and hack the proper wires/sending units of course you can...

The wiring is no problem, but gauge mounting points for the speedo, tach, and fuel gauge are completely different for the Renix and HO housings. It would take some creativity to adapt mounting points for these gauges to swap. The other gauges will swap between the two housings however.

The fuel gauge mounting being different is a bummer, since the fuel level sender is the unobtainium part.  Otherwise it should be fairly simple to drop the HO cluster in and either swap the temp sender or the gauge, the tach and volt meter should work fine.

 

I'll have to try to track down a HO cluster to see how different the mounting is for the fuel gauge.

 

But, this might be the option I want for my XJ.  I want to replace my rusting fuel tank with the later plastic one at some point, and I have only a partial gauge cluster in it anyways.  Hmm.  Too bad I didn't know this before I spent money on a speedometer cable extension (it has a doubler in it).

The fuel gauges are very different as well as the housing construction.

Worst case cut the needed/unneeded piece out of each cluster housing with a bandsaw, line them back up and liberally apply the 3M Plastiwelder. :laughin:

I tried that, or similar. Back when I was calibrating and selling both Renix and HO gauges, I tried to figure a way to mount an HO speedometer into a Renix housing neatly so the Renix guys could eliminate the speedo cable. Hacked, slashed, cut, and pasted a lot of plastics, but never came up with a good practical way to do it. I guess someone who has the right tools and skills for re-forming plastics could do it, but I'm not that someone.

Easiest way would be to start with an HO cluster and go backwards with it.

Mounting the fuel Guage is the hard part, but can be accomplished.

The speedo can be driven using a 91-92 sending unit as they drove the speedo directly, the later 93 and up ran through the ecm and the signal is different from the sender.

Tach is easy 4cyl or 6 cylinder the signals are the same.

Temp, oil pressure, and volts are all the same guages and mount the same, work the same. I have all three US guages from a 92 cluster in my stock 88 cluster.

I was actually working on this very project a while back but got sidetracked. It's on my list of things to finish before I die. A list which seem to grow increasingly longer ... And that's just for the Comanche.
