99? But it's a 01+ ...

It was very hard to find the pinout pin out wiring of the 01 VVT 01+ ingestion spark coils (I added all those words so hopefully this post will come up on google when some other poor sucker is trying to figure it out) From top to bottom it is trigger, ground, power. However, if you dont get spark after pinning the connectors, de-pin the connector and crush the pins down a bit then put it back together. I noticed that the pins on the coil pack side are undersized and sometimes wont make contact with the pins in the harness side connector if you use pins form either bmotorsports or eastern beaver that are recommended for the connector. It is possible that a slightly different pin might need to be spec'ed to work with these coils in this connector.

Not only that, the Madracki diagram from Mazda is wrong on the wire colors. I've wires VVT coils into two cars, both times I had to flip the plugs.

That weird, mazdamaki doesnt even have the 01+ wiring that I cant find. I know that if you do an 94-95 with VVT coils you need brown on the front coil (2/3) top and brown/yellow (1/4) on the rear coil top, black in the middle for both, and light blue on the bottom for both.

Yeah seriously, it's not too hard.

Here's how I problem solved it going from 1994 wiring: look at the 2001 coil wiring, note which leads are tied to ground and note which colors change. Bam, you've just found the GND, +12V and trigger wires.

oh, those are never in the diagrams. I'd have to look at my notes...


looked at notes: 3I, coil 2 = 2&3 3F, coil 1 = 1&4

And the other problem is not knowing which way the connector is orientated in the fsm.

Who cares, match wires to wires.

connector pictures with a double outline are the male, and a single outline are female. and are almost always from the harness side (notice the main relay in the above mentions it's the terminal side).

So it should be looked at, like you unplug the connector, then look into it like this:



i could be wrong. I always just double check.

That is correct, now that I've had a connector in my hand and gotten lucky guessing on a bunch of them (except for the tps, I literally had to try every configuration and got it correct on the last one )

I've wired a few 01+ MSes the way I noted with sucess, so unsure what you're doing...
