I need help with Igniter wiring!!

[integra123]

Hi all,
This is for an 91 MR2 turbo with 93 turbo JDM motor. I'm trying to figure out the wiring for the igniter. Can someone please help me with three thing?
1. On the back of the igniter there are label C, EXT, B, I, F. Does anyone know what each of these letter stand for?
2. Can someone post(write)/take a picture of the plug that goes into the igniter. It should be a 5 pin plug? I would like to see the wiring color and its location to the harness.
3. Can someone post(write)/take a picture of the two pin ignition coil plug? I would like to see the color of the two wire and its location as well.

Thank you.

Someone else may want to know this.
So C = coil negative EXT= Tach (Input) (also check connector)
Check B= Battery I = IGT (output) F = IGF (Confirm fire)

yep, that's it.... and it's pretty constant for all Toyota ignitors regardless of wire colors (because they do vary). Typically the battery is brown and the ignition coil negative lead is black. If the coil/ignitor are strapped together they, many times, will use the same brown 12V lead.

From what I've seen EXT isn't necessary to run.... it's more of a usable signal for the tach
