RHD civic k swapped with rywire rsx k series harness
it shut down and wont start again
ive been testing all the wires and still cant figure out wtf is wrong with this thing

main relay gets power but no ground
ecu also gets no ground
thermostat ground is good at the distribution block


but I cant figure out where the ground goes from the actual main relay?
does it go all the way to underdash fuse box area?
I tested all the ground wires that I could find. the main relay ground seems to go nowhere that's why I'm suspecting it burned inside the harness somewhere but I want to see where exactly it goes around the fuse box
