IF the signal from the W terminal will drive a modified gas tach!
No 'IF' about it - no body has bothered doing it for your mk2 set of clocks for the obvious reason that you can buy a mk2 with a diesel tacho (i.e. GL, GTD and GT models) why would you bother converting a set?
Cause finding a CE1 Diesel Tach cluster is next to impossible in the 'States.

Help!
Need the sensor decsribed here in this post from the Mustang.
Local parts house's don't have any and was told there on national back order
.
Anyone?
Thanks.

I have a friend at ford in Thunder Bay ON, she said they had none in stock, and the CAT computer showed none in Canada at the dealerships either. She suggested trying to cross reference it with jaguar, or volvo. They used some of the same trannies and sending units.

So now make that an international back-order
.
I'll look back through the posts and see if anyone was able to make the VW crank sensor/RPM sensor work. If I remember right, it needed to be pwr'ed before it would work, but might not be the right amount of volts to work?

Question.... I'm working with a gas tach from a '83 Westy GTI.
I'm in the middle of soldering this up and have a question about RV1.
RV1 has 3 legs. 2 are on the same side and there's one odd, on the oposing side. When soldering the 22K resistor to the circuit board, am I ignoring the odd leg? Looking at the back of the board, it doesn't seem to lead anywhere.
Also, what's the benefit of the 3.3uf cap across the needle wires, if it's not critical?
***Edit*** just got back from overpaying at Radio Shack. Now, they didn't have the 3.3uf, but the (seemingly knowledgeable?) employee told me that a 4.7uf would be very close. Should I continue searching for a 3.3uf?

Hmm, that's a lot better than using JB-Weld.
(which I've seen a few people using megasquirt on gassers do)
Nice work!

Thanks. I pulled the sensor out yesterday and realized that I had placed the ring magnets on oriented so that their polarities are repulsing the polarity of the sensor. I'm going to have to pull them back off, countersink the other side of each and reinstall. Not a big deal, but I thought I'd mention it as something to watch out for if someone is doing similar.
Nice work...are you still going to shoot the sensor at the edge of the wheel/pulley?....the magnets just may be strong enough to induce an eddy through the steel of the pulley....let me know how it turns out....and dang I was through flag back in november...I did not even think about looking you up....maybe next trip?....plus I was having mild altitude headache all night at the hotel....Jimmy

if any one is interested I may be able to locate a few of the ford speed sensors....I frequent the scrap metal yard and I will keep my eye out....

Yes please. I'd like two if you don't mind.

I'm clueless about Fords... where exactly on the transmission would I find this sensor? The speedometer hole; is it accessible from the engine bay or do I have to get under the car?
1999+ Mustangs and what years of Probes? Thanks.

Mustang is a rear drive car....so you will have to get under the car to access/remove the speed sensor....Probes?....probes are front drive...not even sure if they use a similar sensor....

Hmmm.... I thought I saw mention of Probes for the sensor.
OK, if I'm under the car, I'm under the assumption it's in the tunnel. Am I just following a speedometer cable or something?
Merry Christmas, everyone.

just thought i would add a different PCB to this thread, just in case anyone else comes across it!! i found this in some clocks i had bought to convert
is as standard front and rear...
this is the slightly different circuit :
as you can see, all the components that need changing are all there so just follow regcheesemans original modified circuit for what needs changing!
this is the basic lay out drawn by myself lol
and this is what mine looked like when finished, i didnt have all the 100% correct components, but made do and it seems to work (reads high @ low RPM i think, OK @ 3K RPM though compared to my mk3 golf tacho)
hope that makes sense, and helps someone!
