Speedo Recommendation.
Post by bluesman2a on Sept 15, 2006, 3:11am

I finally got around to calibrating my speedo tonight, and thought I would pass on the experience. Thus far I am extremely pleased with my new guages, but the speedo takes the cake.

In order to calibrate, you only have to drive a pre-measured mile, start the calibration before, and end it after. It will adjust for new gears, different tires and all the other stuff!!! In checking it against the GPS, it's a little off, but you can adjust/fine-tune at will.

Last but certainly not least in reading the documentation, they are rated for EITHER 12 OR 24V. So if anybody is looking for new guages with the old trucks, here you go:

I looked at the electronic one, but ended up with the manual due to $$$. Now, my speedo is 40% low. Guess I should have spent the $$ for the electronic one.

Did you get the sending unit to fit on the xfer case, or did you get an adapter and plug it into the end of the stock cable?

Nice gauge....good scale for the modified or stock truck...doesnt need to go any higher than that. They are nice to adjust versus the play with a pile of gears and no the math methods...

I am interested in the hook up as well...

There are a couple of ways to go about this... I chose to get a whole new unit. It's a Hall Effect sending unit. It's small has a 90* on it, so it will fit into tight spots and was easy to work into my wiring harness. They come with different threads, I got mine to fit an NP205.

It's essentially 3 wires, a ground and the other two go to the back of the speedo. Also makes it nicer for trying to figure out how to run your speedo cable.

Ok, let me re-phrase my question - would that work with a stock 200?

Boy, I wished Bluesman leaved next door to me, he's got the ticket on this M715 modification stuff.

Yeah, but will it fit my drill?!

I cannot say for sure, my 200 was gone long before this came along. But I CAN tell you that the thread is a 7/8-18. I don't know what the NP200 has. I also know this is standard GM and will work with every other Jeep I have worked on (Dana 300, Dana 20, and QT)

How does that sending unit attach? ?Do you plug it into the end of your speedo cable or does it plug directly into the t-case with a short "cable" that replaces the original? Thanks. That looks like a nice price. All the other speedo (electronic) I've looked at were $200 PLUS a $100 sender.

Post by compexp on Sept 16, 2006, 10:56am

sending unit is separate, iirc.

The sending unit attaches directly to the xfer case. It has enough cable that I was able to route it along the frame, up the driver's fender, and run it through the firewall with the rest of the harness. I had to add about 3' of extra wire for both of the ones going to the speedo.

The speedo itself is $115. The sender is $60.

If you need a full set of guages, the hotrod kit is a better value since they include all the senders and guages for $280.

Thanks for the info. Since I just installed that Hurst shifter, it'll be a bit before I get new gauges, but I think this is the one to go with. <g> It'll be nice not having to use the GPS all the time!

Hang onto the GPS, it's handy for getting the speedo calibrated. Once you get the general speed set (travel exacrly one mile), you can fine-tune it. I used the GPS to fine-tune so it's dead-accurate at 65MPH.

Nice. Would like to see a pic from the dash with this speedo.

Wow! Those pix look good. I like the idea of having ALL gauges the same style. I might have to spring for the set. Are all the senders electronic, or does the oil pressure gauge have the little oil tube and the temp gauge have the thermocoupler permanently attached?

All the ones I have are electronic (oil pressure sender is the little can-looking thingy that gets plumbed to the block then wired). But VDO does sell the same line with mechanicals if you want them.

Again, if you're looking at the whole set, it's MUCH cheaper to get the street-rod guage kit in the style of your choice. I made the mistake of NOT getting it and had to get all my senders and such separately.

Wow. I didnt expect that they look soo nice in the dash

Re: Speedo Recommendation.
Post by fsjguy on Sept 19, 2006, 7:54pm

Good to know. I'd prefer the electronic one. I don't want a pressurized oil line coming into the cab. Also, all wire connections make it easy to remove the cluster if I need to.

I'll have to remember to look up the VDO kit when the time (and $$) comes. Thanks!
