The guys at workshop were quite professionals, they kept an organized register which had wiring diagrams of many ECUs of toyota and honda, except BT, so next day i took prints and gave them, quiet excited they were! still i kept questioning them for wiring,and gave them insight of what was already there. I am glad that fuel pump is operated by ecu through Fuel Pump relay i added.
Wiring didnot had fusebox included, so they had to join it with car wiring. wires were taken out and they did well, still i am going to check connection someday IA!
Funny incident occoured when check light was not turning off. Senior-Junior Electrician Ustaad tried to diagnose, but it was not going into diagnostic mode, so he checked with another ECU, (by the way i forgot to tell that its 5-forward Manual Transmission), so Senior-Senior Electrician Ustaad came into play, took his 3g-enabled set, googled diagram for BT 4AGE and checked connections and i was like WHAT!!!! the problem was with the MAP wiring which wasnot there on the first place and added later on, so he fixed it and took good 'khabar' of others!
