I posted in one of the other threads how I had some success getting the ETAC modules to power up in my lab environment - thanks to my loom that interfaces to an OBD2 connector, which can be patched into the WQ OBD2 port. I thought I had best share the wiring setup I had for my test loom - it's showing mainly how I am interfacing the EATC module and does not visually represent the OEM LS loom itself - other than the loom desgination and colour from the table. For reference, the table shown is for the WQ Fiesta Single ZOne EATC module. I'll dig out my comparison of pinouts to the LS EATC module.
