ODB2 Hidden Pigtail (Pre-Under-Dash Port)

@SCOPESYS also, if you have any suggestions where to tuck the actual devices under my dash, I am all ears. Between the switches, my custom harness, the relays, the 6 inline fuse box, the device hardwires, the custom oem splitter, the 3 device splitter, and the 3 odb2 devices themselves, I got no more under dash room.

I am actually considering disassembling the whole set of mods to shorten any wires that can shortened to pull the harness up into the dash farther and save a few cubic inches of space.

I have not installed my solution yet, but you might consider mounting some of the wiring etc, near the front center speaker.
The center speaker is easily removed with a plastic try tool, and there seems to be quite a lot of room in that area.

Another place is behind the glove compartment, where the air filer resides. Seems to be some space there as well.

Maybe the key is to have quite a long cable from the 1st T to where you want to the additional splitters where you place the additional items.

Having the additional items Hidden away would seem to be an advantage, but access able from say behind the Glove Compartment that is easily removable for service & access.

@SCOPESYS was this location the one you were referring to? (Though the drivers side upper side dash panel)

I was thinking more BEHIND the passenger side Glove Compartment.
This is removed for access to the Filter, so provides a reasonably secure & hidden space, which can be opened up for access, but is not obvious that anything is behind it, to the casual observer (or car Thief)

@SCOPESYS

Ah, yeah, that too. I was referring to your "behind the fuse box" suggestion, but I guess this space is more "above the fuse box".

I took a look at the space behind the glove compartment, the is done, may accommodate my odb2 devices, but definitely not the fuse box and relays.

I plan to work on this more next week, so I will update then.
