Line End.jpg

I want to ensure I will be able to flash my ECU. However I have been a little over zealous in my wire diet!

The test mode connectors B76 and B75 are the green connectors that are plugged together to complete a circuit to allow test mode. From there B126 and B125 make up the "Line End Connector" (Located on WI-71) E/G (TB)-05

Does the BW (Black White) and Or (Orange) wire remain connected together at that junction during normal driving operation?

or

Is that connection only made for tuning or other diagnostics?

Thanks in advance!!
