Does anyone have the wiring diagrams for an NA miata? I'm doing a wiretuck and there are a few plugs which I am wondering about. Some examples are the ones going to the evap purge and the "little black box" that is grounded next to the power transistor. They use the same connector, so I want to make sure I use the correct one and junk the other. One connector has a blue and I believe black wire, with the blue wire part of the transistor plug wiring, and the other is a yellow/red, and i forget the other wire color now...

 

Whenever you ask such a question you should include the year of your miata. NA just doesn't cut it.

whoops sorry, I have a 1990 miata.

 

A wire tuck... Jesus, this is painful.

The "power transistor thing" is a capacitor. Specifically, it's your ignition condenser. Blue/Black.

 

OK that's what I assumed as well. It was a long day, cut me some slack will ya
