This side of the harness almost looks stock for the moment. But the extra rings & wires on the body ground (G201) are a clue that it's modified. One of them is the new trunk ground wire that runs from the factory ground screw on the driver's cowl horn to the L fender to the core support to here to the aux.batt. relays to the factory screw for the intake RFI strap on the R side of the cowl, providing redundant grounding to all the body panels, and connecting some of the factory remote body grounds almost directly to the battery.
Yes, I eventually cleaned & painted that battery tray.
