is there a difference in the dohc mx-3 ecu pinout & the miata 1.6l dohc pinout

I cant tell you Which wires are different.. I can tell you there is at least one difference. The miata's were a distributorless engine.. relying on coilpacks for ignition.. as such the system needed and had a crank position sensor which our B6 engines didnt have.

then they are different boom slang has an harness adapter from the miata to plug & play a sfac, i emailed them before about making a harness, they will, but i posted in new products & really got no response.
they also make adapter plugs

Hey Monty!

The earlier B6 Miata engines had disties... I don't know what year they switched, but they haven't always been distyless.

Thats weird Pat.. cause napa showed distributorless for the B6 in the miata from its production beginning. I'll be heading to my mazda dealer later this week and I will ask them. Doesnt mean Napa's books are correct.. wouldnt be the first time a automotive manual was wrong

In fact.. just now on http://www.napaonline.com when looking up ignition parts for a 1990 Miata.. they dont list a distributor and for a coil they show this..



They also list crankshaft sensors for them as well.

Hey guys I was searching to try to find out what type of crank position sensor is in the B6 94-96. Had no luck yet, I'm sure one of you guys know this, and this would be an appropriat post to ask this on instead of starting a new thread again. lol thanks for the help
