Need help with abs wiring.

[ShooterCM]

I have a short broken wire or something going on with the right rear abs wiring. Any help would be appreciated. Is there a comon place I should look? What's the best way to test the wires. I've found different ways on YouTube.
Thanks

I didnt take any pics but I have all the typical warning lights, traction control, abs system and no four wheel drive. I replaced the speed sensor then found a code for low voltage and correlation.
