Edit


the tach on 99eks come from pin a19 on the ecu.

If i connect the tach output from the MW to the harness side of a19, i get nothing.

If i tap a21, where the output signal is for the MW, i can get the tach to show idle, but anything above 3k, it jumps and falls.


Anyone know how to get a 99-00 ek/teg to have the stock tach work with the pro10?

 

Any help?

 

Wire it like stock. The tach output from the m&w does not work for stock cluster. Only aftermarket tachs and shift lights

 

any other help?

 

give tony a call! hell be able to help!

 

i did. He wasnt too sure on the matter.

 

I guess ill deal with it when we start the car. I just wanted all the wiring finished up before it hit the rollers. But i guess wiring in the tach after its tuned wont kill me.

 

i just taped mine into the dizzy i have a obd 2 dizzy too. my stock and aftermarket tach works

 

Same here. But if u disconnect the tach output from the dizzy everything will still work

 

I told u. Just leave the tach wired as stock. I had to do it also

 

does the stock tach still work if i dont wire it to the mw output?

 

and just to clarify, 99-00 EK and Tegs dont get there tach signal from the dizzy like all other years.
They get it from the ECU.

 

yes, you said the ECU gives the stock tach its signal, well, if the ecu didn't see an rpm signal, i dont think it would even fire off the car.

 

it does in OBD2b form. But i dunno if the OBD1s have the same output. and the wire that is the tach output for the obd2b is where the m&w gets wired into, so its no longer attatched to the car harness.

I gotta look at the harness again, i have a feeling im looking at the wrong pin.

 

This is for an OBD2 to OBD1 conversion, but might still have some helpful info you could use to figure out your problem.
