[Diy_efi] Coils from Toyota/Lexus 1MZ-FE engine...

[Gerard]

Thanks. :) This seems good to me. I forgot to mention the part number,
it is 90080-19016.

One final thing to clear up. With these coils you have, I assume the
+12V doesn't constantly run current through to power ground, right?
Sorry, it must sound like a very daft question indeed, but with the
previous coils I had ground on a mounting tab and the current flowed
constantly. Great for welding, though. :)

Thanks again for the info. I will check these against the coils I have.
Being Toyota stuff I guess they'll be the same and the part number is
simply a "shape" issue. :)
