With all the different problems you are having. Bad electrical connections. Disconnect batteries and start checking grounds then connectors. While connections are apart. Check for corrosion. I good product to use while connector are apart is Deoxit. You can find in on Amazon.

Not sure about relays. Most common is grounds. There is a ABS module.
Have you check the electrical drawings at top of the MDT forum?

My motor cycle friends claim the Deoxit that I listed above works well. Clears up corrosion and makes a better contact.
