Speedo Sender

I'm replacing my speedometer with a VDO. Looking at the FAQ, I need to have someone modify my speedometer cable. Following it down, it seems to terminate at a block near the left transmission mount. Is this the end that needs to be modified? Remove the speedo cable to this point?

Ken instead of that you can just install a VDO sender from a disco or late model defender in your tcase. I have a 3 wire VDO sender from a 2002 d-90 right in my t-case. The wires then go right into the speedo. no cables or adapters.

this link shows one sender http://www.defendersource.com/forum/...ght=vdo+speedo

this one shows the wiring and my sender http://www.defendersource.com/forum/...ght=vdo+speedo I wired mine whis way and it works great.

Does that work with 94s? Because you still need that little box that Ken has pictured so the ECU gets the right signal. Other wise the ECU will throw a code.

Disco sender does not work right with a 94. There is a write up in the FAQ section I believe on what has to be done for a 94. I did the same...Contact North Hollywood Speedometer and have them make you an adapter cable that goes between the box and the Hall Effect VDO sender. They made mine, and it fits right on. While you are at it you can have them also adjust the mileage on your new VDO speedometer to read th same as th stock one you are replacing.

I gots the parts and pieces, I just need to figure out what to put where. I read the FAQ and the several write-ups. Dave Souza mentioned a speedo shop in Maine, I think too.

So do I have the adapter made out of the original speedo cable connecting this box to my new electronic VDO sender?

Connecticut is where I found. I haven't done it yet, just been lazy. I intend to remove the entire speedo cable, and send it with the VDO hall effect sender I bought into the speedo shop with the instructions from the FAQ (which detail the length and the required fittings). If they can update the mileage like Mark says, I may include the speedometer too. I only spoke with the guys at the speedo shop once, but they sounded very knowledgeable. I don't think it's a big deal for them to make this mod.

Dave, I thought that you already had yours installed. http://www.defendersource.com/forum/...3&postcount=28 Damn, you're almost as bad as me. I've had these boxes sitting in my living room for about 2 months, now. Did you just have VDO fuel, temp, pressure guages installed at last fall's RC trip. Does your speedo have just miles or does it have kms too?

No, actually, it was "pussy", and I did say that to your cyber-face.

Glad that you had a successful trip this weekend. At least you didn't break anything on your truck!

I sent my cable, VDO Sender and Speedo all at once. They did not use the cable just needed it for reference so they can put the proper connector on. The custom cable should be about 6" long. Screw the cable into the box and use some electrical ties to hold it in place, attach the hall effect sender to the other side and route the wires up to the speedo.

BTW - at the same time I replaced my lower speedo cable also, while you are in there, get it done, seemed to run smoother after that.

Good luck,
Mark

Ok, to show my ignorance here... There's two speedo cables? And it's the 'upper' that goes to the speedo shop? The lower stays where it is? And Ken's picture above is of which cable?

In Kens pic you are looking at the transducer and the lower end of the upper cable, it runs between the transducer and the speedo. The lower cable runs between the transducer and the T-case.

Cool, and Dave after it's done take some pics and post them, this seems to be a popular conversion and we have very little documentation on how to do it.
