qusetion on Toyota ignitor

[bigaaron]

This ignitor happens to be on a Supra but my question is more general.
The inputs to it are labeled iga, igb and igt. Are these inputs multiplexed? I know the inputs to the ignitor are 5v but the test procedure shows putting 3v to one ignitor wire for coil a output, but then you must apply 3v to 2 wires to test coil outputs b and c. Any insight would be helpfull.

I got this answered on another forum, if you are interested.

Re: Using JZ's igniter in 7M-GTE (+)
Dirgle, you are the f-ing man! That is exactly what I was looking for!

IGT tells the ignitor when to fire a coil.
IGA and IGB together determine which coil to fire
IGF tells the ecu when a coil has fired
