Blitz Fuel/Timing Issue - Toyota Yaris Forums

We are not having success using the AEM EMS-4 Standalone ECU therefore how will I go about using the 8 wire blitz fuel controller without the activation switch and relay?

This is what I have gathered so far....
1Pink: C20-81 (IGF)
2Red: [4] A21-28 (ign switch)
3Yellow: [5] C20-107 (inj#2)
4Orange: [6] C20-108 (inj#1)
5Green: [9] activation box
6Black: [10] C20-44 (battery -)
7Blue:C20-105 (inj#4)
8White: C20-106 (inj#3)

I know there is a 9th wire? where does it connect?
I am correct in saying that the 8 wire fuel controller does not connect to the MAF sensor?
