They programmed the speedo before shipping it. Not sure if they did it or rec'd it from VDO that way.

I'm pretty sure they have a way of writing a mileage to the prom as long as it's larger than the previous version, and don't do it the hack way.

i'm sure they do ... I'm just suprised how difficult it seems to be able to find info on how to do it ...

I am guessing it's a combination of a easy money making opportunity and concerns about fraud if it's super easy to do.

My 95 NAS upper speedo cable took a crap and after digging thru the pile of parts between the transfer case and speedo, I plan to switch to the VDO with transfer case mounted VSS.

I am thinking of getting the YBE100530 instead of the 40 and am wondering if The wiring diagram Red posted in #33 and the 120 Ohm .25 Watt resistor are the same for this VSS.

Also, has anyone been able to program the odometer other than having it done from the likes of Egauges?

Any input is appreciated

If you order from Hollywood Speedometer they will program the odometer for free.

I used the resistor from the old VSS which i extracted during open VSS surgery. Tapping into the other side I ran a wire up to the speedo. Grabbed a 12v feed from the ones feeding into the other dials and attached a ground.

A few minutes calibrating against the GPS and voila!

I just did one of these last week and was a little confused where the resistor went as Jason has it inline with the ECU feed and Red's diagram shows it after the VSS. I ran it inline with the feed and no problems yet.

The magic of electrics is that it doesn't matter ... As long as it's in line somewhere on the circuit it will have the desired effect.

Will the 530 work the same way?

Using the same resistor?

The other sender is a Hall effect sensor. It won't work with the EFI. It will work with the speedo by itself and no resistors are needed.

The resistor is needed only when connecting to the EFI as it is drawing too much current when sampling the signal

Thanx Red! Just the answer I was looking for.

I will stick with the 40 and do the resistor.

Yes my brother but whats that got to do with your speedo? No need to unplug the vss signal routed to the ecu.
Whats cool about the gps based speedo signal is that its always right regardless of tire size etc.

Hmmm

Didn't think about that. Had an all or nothing plan stuck in my melon.

That may be the plan.
Thanx

As long as you don't live in a built up area like NYC such a thing should be fine. In NYC it would suck big time ... The only way you'd know your speed is from the writing on the moving violation.
