IG1 pin 11 black wire. The 1JZ haves only 1 signal. I think it comes from the ignitor.
Contact the Mfg. of the meter they should point you in the right direction from there.
You can try to change the cylinder setting the coil packs might use waste spark technology.
I think it uses 3 seperate pulses to fire 6 cylinders. So maybe try 3 cylinders.

IG1 is the signal going TO the ignitor. Try connecting to the IGT signal beside it, which comes FROM the ignitor.
IF1 says "fire ignitor 1"
IGT says "I've fired an ignitor"
IGT will read 6x higher then IG1
