Electric speedometer

[70barracuda]

I have had it with the speedometer cable. I'm on my 4th one and all of them have leaked out the crimp at the transmission end. I'm running a Tremec TKX but it provides a mechanic and electric speedo output.

 

I was using an adapter on the trans that allowed me to keep the original cable. But that started leaking. Now I'm on my 3rd one of various designs and they all leak out. Is there an electric speedometer I can swap to my gauge cluster? I really like having the stock look with the blue face gauge and giant gas gauge so I really just want a speedometer. I think I saw the 115mph police one is electric and blue faced. Provided I can even find one is it possible to swap?

91 to 97 speedometers are electric. You should be able to find a speed sensor you can fit to the Tremec to drive it. You will need a 91 to 97 cluster so you can power the electric speedometer. All the other gauges should be interchangeable, except maybe the fuel gauge. Not a hard swap.

Could also use a universal gps unit from Dakota digital and just program it to the 91+ electric speedo

I slathered some RTV on the spot that was leaking and so far so good. Still going to maybe work on a 91+ gauge swap.  The GPS idea could also work. The holley dash I want uses that for speed. But at $2k it's hard to justify...

 

Maybe I'll work on a custom gauge panel using a factory enclosure and aftermarket gauges.

It's a bit of a crappy situation.  The 91+ cluster swaps over, which gives you the electric speedo, but you can't put the 84-90 fuel gauge in it.  I think Hornbrod spent a bunch of time messing with this, but maybe it was someone else, but they did manage to glue/splice the different year range fuel gauges in by cutting out a large chunk of the cluster and putting a piece from a donor cluster in.  So without that you're stuck swapping your fuel sending unit too, which I think is a really hard find.  MTS may start making them, or may have made a few?

 

Also, the cluster size is actually quite small, so most of the "normal" sized aftermarket gauges won't fit in it nicely.

 

It's something I haven't solved because I'm wanting to run a diesel/universal tach and a 97+ fuel gauge in a cluster that looks good.  So far I have no great ideas.

There are a few aftermarket gauge options. I’m planning to go quite custom on my build but the options I also came across was the intelliteonix create-a-dash and the autometer invision universal kit.

Correct. The pre 91 cluster had the fuel gauge work 0 - 88. The 91+ worked 105 to 5. You can do what I did which is to take the circuit board from behind a pre 91 gauge and wire it to a 91 gauge. It then works correctly. I have no idea why Jeep engineers felt they had to change it for a 91. The actual gauge is the same.

Any reason why you can’t put the 91+ speedo gauge into the 87-90 cluster and simply run your own wiring/harness to the speedo sensor on the transmission?
