Thank you for those links.

At my skill level, the electrical details I consider are beyond me in most
ways and from one point of view, I'm really "splitting hairs" here when I
probably don't need to. Distinctions between how Bentley labels a given
ground point, i.e. where it's located, wire length to it, and whether or
not adding or subtracting wire length to a given ground path matters, may
not. I guess what I'm trying to say is that from the layman POV for most
people doing a swap, running all the engine management grounds to one or
two locations shouldn't be a problem. Ironically, on my currently running
swap, one "sensor" ground wire is shortened by 90% and AFAIK, the sensors
work fine. (yes I corrected a long standing mistake!) And, swappers end up
cutting up (shortening) the harness as it is anyways. e.g. wires to/from
the TPS. But as I say, "At my skill level... "

;)

Knowing a little more now on this second harness, i can see that ground
locations, wire length, likely has more to do with the design of the
vehicle and component location rather than millivolt considerations. .....
I think.
