It is easier to splice into the wire harness in front of the ABS control. There's a lot more room to work with. I wish I had wrote down the color of the wire I spliced into, but I didn't. There was a thread going back around 2013 or 2014 describing just what to do. For some reason I want to think it was a blue wire but I'm just not sure. I'll do some looking around and see if I can find the post about tapping in there.
