where is the obdII grounded at?

im trying to find out where the obdII is grounded at so i can take the ground wire from the lm-1 and ground them together at the same spot.... im searching for ground variances... since my lm-1 and efilive have a variance...

I am also wondering about this, I would like to ground my wideband/HPTuners to the OBD II ground wire, instead of grounding it to the EIO interface.

On the OBDII connector, pins 4 and 5 is the (signal and chassis) ground. EFILive's ground is connected to those exact pins. You will see no difference by running the LM-1 ground wire directly to the location of the OBDII connector ground.
