BTW-do thundra coils fit in the Miata valve cover, and how far do they go in, like are they flush?
Can you snap a pic cause I remember some people asking this.
I hope you picture taking skillz are better than your wiring skillz, yo!
8 more? I bought 8 so I would have screw up room. The ones I did that to don't appear broken, as they're in my motor right now and still functioning.
Anyway, with the tundra COPs, the little plastic triangle that comes off of them that you use to anchor them comes off at a 90 degree angle from the wiring plug. No matter how much you turn it it won't fit in between the camshaft humps in the valve cover. However, having 8 of them, I did a little R&D. I sawed off one of the anchor triangles and then dropped it in, and although it's now clearing the cam humps, it comes to rest at the exact same height that the others do. So although it fits flush on the spark plug, the coil pack is slightly taller than a stock spark plug wire and you end up with about 1/3 of an inch between the rubber piece on the COP and the valve cover.
The only way to run the coils is with the anchor in between the camshafts and then the wire plug sticking off of the side. It works though. I'll take pics when I get home from work.
And yes I know I'm a noob with wiring when it comes to ignition systems. My real fault with this job was that I was trying to just do a mock up test with the hardware before I cut the plugs off, and that was my real issue.
I did build my own megasquirt though, and it appears to work. I haven't installed it yet though.
Edit: Also, regarding the tundra COP's, they've got the same wiring setup as the 2003 corolla ones, or it seems most toyota COP's. From left to right, with the plug facing down:
1 - Ground
2 - Trigger
3 - Tach output
4 - V+
