Hello, I’m new too the ecu world so be easy with me. I recently had my 2jzgte engine built. A custom wiring harness was also fabricated. My harness did not come with a can bus built in 
. I just purchased a bti gauge but have no clue what wires to splice into. My question is if I plug my ecu into my laptop can I find my can Hi and can L on the software? Any help will be appreciated on finding those 2 dam wires. Thank you
Probably start with what ECU do you have?
Sorry, I have the emu black
