ABS wire to hub - where is the otherside of the wire?

I have a 2006 Pontiac Montana SV6. The ABS/TC isn't working. It's not working because of the driver front wheel. I fixed it once by buying a new harness pigtail and then spliced it in. But the wiring down by the wheel hub is extremely brittle. When I was trying to splice it in, the wire to the car was basically breaking off as I was trying to splice it in. I spliced it in as close to where all the wires go into a huge bundle. The van's ABS worked for a few weeks and then quit again. I know that's the spot it's broke. Only thing I can think to permanently fix it is to splice brand new wire to the pigtail and then run it to wherever it goes where it hasn't been weathered for 10+ years and the wire isn't all rotted. Does anyone know where I would find the wire where it runs into the ABS control or ECM or wherever it runs? I'm sure if you can tell me the area to find it in, I can confirm it by using a continuity test with my multimeter.

Hi !
Rather wire break in the sensor.
This is the most common failure

I forgot to mention that my first fix I did to attempt to fix the TC/ABS was I replaced the wheel hub which would've fixed what you're showing the the picture. I replaced the wheel hub because I didn't want to cut the wire. I knew as soon as I cut the wire, then I would have a spliced wire that is never as good as the factory wire. After replacing the wheel hub and that not working, I then replaced the end of the ABS wire. But I still really suspect the splice. I want to splice it in where it hasn't been weathered for 10+ years. I want new wire. Unless someone reading this thinks this isn't the problem. I just know when I spliced the wire, the wire was basically breaking off as I was trying to splice them together.

Hi! You can buy the ABS. From the hub to the brake modulator

Does anyone have any detailed instructions on how to replace the whole wire? I was looking in the engine compartment where I think it is the brake modulator (under the master cylinder) and I don't see where these wires are plugging into. Before I start thinking about changing the wire out, I need to know exactly where the other side plugs in.
