Ecu Wiring Pinout Diagram

[neuro]

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.

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!

You can get the Speedo wire at the back of the dash clocks.

Red with Yellow trace.

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)

It's easy peezy to get those clocks out, I did the speedo Mph mod for my mates Altezza in little then 15 minutes...

alright then. That would be my last resort.

Are there any cables plastic bits i need to pull out first from behind the speedo clocks? Or are the wires visible enough to trace?

Thanks mate.
