It would need more than just the ABS controller, it would need speed input (and probably more) from the puter and power to the ABS pump.
If you powered up the vehicle enough to do all this, it would be racking miles as you tow as well.
Pretty much was I was going to say. With todays computer controlled cars, there's all kinds of input to the BCM or Body Control Module and, the ECM or, Engine control module and even the TCM, Transmission Control Module. All those things work together on a second-by-second time frame. And this includes the ABS system. So, even if you could "Hotwire" the ABS system, you may be back feeding power to points it's not supposed to go. Just a few thoughts here.
