I am converting from NA to Turbo (Rev 3) and would LIKE to keep the Electronic Speedo in the Rev 3, and therefore just pluging i the new dials unit, but my NA had cable drive speedo. Question is does anyone have any wiring diags for wiring up the electronic speedo unit.

Looking on the back of the unit there seems to be FOUR wires to be looking at.

Can anyone help.

Thanks

You will have to replace your instrument cluster as well.

Yep got the instrument clustter BUT I beleive I will have to do some rewiring from the instrument cluster.

Any ideas.

By the way I am replacing the loom from the LEFT kick panel all the way to the engine/boot.

The 1991 and 1992 MR2(and prior of course) are the only two models that came with a speedo cable. 1993 and up were electronic. You will have to get the wiring diagram from a 93-95 book. I only have the 91 manual. If you want the wiring diagram on a 91, I will be glad to email or fax it to you.

Sorry I can't help more.
