You could ditch those two switches and consolidate into something much cleaner, like one toggle switch. Looks like the the previous owner accomplished his goal, but not in a very logical way.
Here's what I did:
OTRATTW parts:
1. Switch:
SKU: V1D2UXXB- Contura V Upper and Lower LED Independent rocker switch
2. Switch rocker cover:
SKU: VVAXCYT-HAH - Contura II – custom text rocker switch, rocker only. Top line ABS on, Bottom Line ABS off
Wired it up to cut power to the ABS module. 1 Relay for logic, 1 relay for power cut to the module.
Now it’s a LED-lit toggle switch. LED appears on the top or bottom, in the position it’s in (off or on)
Here it is in action:
