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

[don.broadus at exeloncorp.com]

The coils I have are Toyota  90919-02238 Denso from a 4cyl. DOHC engine that
was not in the car so I don't know what it is out of. If your looking at the
4 pin connector  Right to left

           ------ 
		4321
           ------         
  1= +12 VDC         
  2= power ground
  3= signal hi
  4=signal low
The connectors  I got have color codes   +12V black/silver dots   power
ground Black/yellow
signal hi  is different for each coil (green/red) or (Red/Black)or
(red/yellow) or Red/white) for 4 cyl. apps. signal low white/black   You can
tie power ground and signal ground together. The Smart coil will fire with a
pos going +5V pulse. With 15Hz square wave pulse you get great sparks with a
.060 gap plug. The smart coils draw 6.5 amps at 11.5 VDC from 15 HZ up to
10KHZ.  50 HZ  would be approx 6000 RPM.      Take Care

Hi!

I went through this kind of stuff a while back. I was looking for info
on the Beru coils used the BMW engines (6-cylinder from 328 and M3).
Also got help from this list in figuring oil some odd coils I had.

I now have coils off a 1MZ-FE 3-litre V6 from a Lexus or Toyota Camry.
These have 4-pin connectors and I am looking for any information on how
these wire up. I have been to a Toyota dealership, but surprisingly they
didn't have much help.

Anyone ever do some ignition work on this engine and can help with info
or wiring diagram? I'll be doing some searching online as well.

Thanks.

Gerard.
