Ecu Wiring Pinout Diagram


Recommended Posts

Hi all,

Would really appreciate if you guys can help in figuring out the ECU wiring pinouts for speedometer readings.

I just bought a greddy turbo timer with speedo display, time/distance modes, etc.

It's such a waste not to be able to use any of these. :crybaby:

A local workshop technician was not willing to make a guess, as he said any wrong wiring would fry my ECU unit. I have a '2000 Altezza by the ways.

Thanks so much whoever can help!

Actually that was one of the first options.

Hmm, its a bit more difficult to trace the wires from the back of the dash facias.

That would require a lot of dash bits to be dismantled.

I prefer it to be in the ECU instead. I fear pulling apart the facias would mess up any wires/cables behind it, or even cracking some plastic bits. (it happened before) :crybaby:
