Still in the very preliminary design of my conversion. Mostly hypothetical CAD design lacking the donor vehicle yet. I've been looking at a number of the smaller components like HV connectors that support HVIL. I've read that HVIL can be pretty complicated including square waves monitored by controllers.

Long story short, I am big into safety in this design. How is the DIY crowd wiring HVIL into their systems. At minimum I'd like to use it to prove continuity through the battery system prior to allowing the traction controller to come online, but I can't find much info on how it's typically wired and/or used. Would love some help on this one, especially in the early design phases.

Commercial HVIL loops are more complicated, they use PWM and can sense interruption and grounding separately, as well as where in the loop the fault is (not sure how that works, something something resistors). So presumably they use HVIL to close the contactor via a separate relay/voltage.
