And here, in post #33, is a torrent for what appears to be the whole Toyota service anthology CD: http://au.toyotaownersclub.com/forum...pic=7385&st=25
(I haven't downloaded it yet since they block bittorrent clients at work)

Toyota:
1-ground (brown)
2-trigger (color varies)
3-tach (blue with yellow stripe)
4-V+ (black with white stripe)
These colors are the same on all four connectors. The only one different is the trigger wire depending on which cylinder it is. I have already removed the 2 EGR solinoids, purge solinoid, and fuel regulator solinoid from my car. When I wired the coils I re-pinned the EGR signal wire (from the EGR position sensor) into coil-3 out and used the purge solinoid wire and re-pinned it to coil-4. I had to untape the Miata harness to get the purge lead over by the coils. Inside the Miata harness the stock coils all wire up to only 5 wires. Power, Gnd, 2 signal wires, and tach. The tach leads from the OEM coils are connected together in the harness as well as power and ground.
Some of this information is redundant. I thought I'd explain how I did it. Start off by connecting all four Toyota coils in parallel except for the triggers. Then connect the triggers from 1&4 together and connect it to the Miata trigger for those cylinders brown with yellow stripe. Then connect the triggers from 2&3 and connect them to the second Miata trigger for those cylinders solid brown. If you get those two browns backwards you'll know, just reverse them.
Edit - Ok I'll make it easy on you guys.
Function.........Toyota...................Miata
Ground...........Brown....................Black
Tach..............Blue/yellow.............Black/white
Trigger...........Varies....................Brown/yellow 1&4, Brown 2&3
V+.................Black/white............Blue
Now that I think about it, all the tach wires can be connected no matter what your ecu setup. I may have done it that way I'd have to look.

Did you get the connectors with them? I dug in 2 junkyards for 2 hours before I found those plugs. I even tried other connectors from different cars hoping to get lucky. Ironicly the Miata TPS sensor plug sort of fits. $20 is a deal for the set of coils. I believe the dealer gets $130 something for them. Better keep it quiet or the next thing you know there $75 a pop on ebay.

I think what you guys are trying to do is very cool.
Flippy just got his coils for $20. Let the purists spend $400. Not me. I'm a DIY guy.
