Mikzu's 4A-GZE project

[Jousi]

Hi! Could you help me a little with ignitor connection? I have GZE ignitor but i have to wire it from ecu and on the web there are not enought info about those wires. There are those 2 connectors on the ignitor, and as far i know, smaller 2 wire connector are outputs for coils, black for coil 1,4 and blue for coil 2,3, if i am right...
But the bigger, with 5 wires are totally blank for me. In all wiring diagrams they show only three wires going to it, and the colors arent same on the ignitor side. I have colors on the upper row, left to right: brown, grey, red. Under: yellow, white.

Could you tell me what are colors (and meanings if you know) on the engine wiring loom whitch connects those colors?
