Does anyone know anywhere I can get an OEM 12A Turbo wiring harness, or diagrams?

 

Any factory diagrams would most likely be in Japanese unless you can find one from Australia which also got the 12AT. You might try Ausrotary.com

 

Won't let me register with a gmail account. F*** ausrotary.

 

Yeah, I couldn't register with a free Hotmail account either. Apparently one needs a paid account to weed out the spam or something.

 

back in the day you could search without signing up, and i did find a diagram. although it looked like one page was from one year and the other page from another, in other words stuff was missing.

AND its in japanese, i think all the AUS delivered cars were 12A non turbo

this is why ALL of the aussies run standalones, they don't know how to wire it up either.

its possible mazda has a 12a-t harness new still, but mazdausa won't order it for you. and even if/when you do get it, it goes to the wrong side of the car.

 

From what I understand, the Aussies did get the 12AT since they didn't get the 13B SE. Another option may to keep an eye on the importers for a 12AT. You may have to buy the whole thing just to get a right hand harness and the 2 ecus.

 

I had the 12at wire diagrams saved on my computer for a long time but they some how got deleted sorry. best car to swap one in is a gsl se from what I understand its pretty close on wireing already.
