Alright question:

Is there a difference between the two ground pinouts on the ecu?

^^ using that page as a reference, slots B2 & B10 are listed are grounds, is there a difference, is one the main ground and another for something else? Thanks..

 

bump...anyone?

 

Depending on what you need it for you could use it for anything, there just grounds. Usually i dont use them i just use body ground.

If you need to wire them up fine out exactly where they go and wire it accordingly.
