I am looking for the tach output, oil pressure, and water temp outputs on the stock harness. I installed a microtech LTX-8 and there are 2 yellow harness connectors just sitting there but dont know which is from the gauge cluster. I need to know the color wires for each so I can splice with the microtech harness.

Please any help would appreciated
already asked on microtech forum.

 

You can tap into the tach signal by finding the Yellow / Blue stripe wire coming from the smallest yellow ECU connector. Just find a long section of that wire and gently peel back a little insulation and wrap/solder your signal wire to it.

The oil pressure sender wire can be tapped into at X-06 connector. That connector is at the driver side kick panel. Remove the panel and you're looking for a large blue connector there. Once found then look for a Gray / Red stripe wire. Tap into it like above.


The water temperature wire can be tapped by finding X-14 connector right above the stock ECU. It is a large white connector. Look for a Yellow / White stripe wire that is coming in from the ENGINE harness. On the other side of the connector it turns to a GRAY wire. That's your wire.

I tried using a aftermarket tach to test the tach output and nothing.

As far as the water temp sensor I cant figure out where it is since I am running a Microtech and dont have the white connector. Where exactly is the water temp sensor located?

If anyone has a link showing the pinouts for the 2 yellow connectors coming from the dash and cluster it would be nice or let me know what page on the workshop manual I can find them

Damn microtech, why is it so complicated

 

Water temperature sender is right under the oil filter pedestal area, above the oil pressure sender.

EXACTLY what yellow connectors are you talking about ? On the ECU ? Be specific. If you are talking ECU, then manual pages Z-28 thru 41 will tell all.
