Brake Line Lock actual location?

[Melmark93]

Made my first trip to the drag strip last weekend. For an old dude used to toggle switching the line locks, using the app menu was a disaster. Ended up turning off the traction control, doing burn-out & turning TC back on.
I was thinking it would be great if one could "hot wire" the line locks, but I suspect that function is built into the
ABS control. Anyone know for sure?

The ABS module is used for the hill start assist feature, launch control feature and line lock feature.

Line Lock
The line lock feature works in conjunction with the stability control system to "lock" the front brakes and allow the rear wheels to spin freely during throttle application to achieve maximum traction prior to use at a race track. The line lock feature is intended for use at race tracks only and should not be used on public roadways.

The driver initializes the line lock feature through the message center, see the Owner's Literature for specific information. Once initialized, the line lock feature is not activated and the vehicle brakes function normally. Line lock remains initialized up to 40 km/h (25 mph), once vehicle speed exceeds 40 km/h (25 mph) the line lock feature is automatically cancelled. Following initialization the line lock feature can be engaged, once engaged the ABS module closes isolation valves in the HCU to maintain the brake pressure in the front brake calipers while allowing the rear wheels to spin freely and a count-down timer begins. If the line lock feature is not used within this time limit or a vehicle condition requires the line lock feature to deactivate, the line lock feature is deactivated.

Snoop: I actually tested LL and LC for the first time the other day. Almost didn't manage to get LL to work because I wasn't pushing hard enough on the brake. I mean you REALLY have to push to get it to initialize.

The ABS module monitors brake line press and also controls the line lock feature, so there must be a line pressure threshold that must be reached or exceeded before line lock is initiated.

I'm going to seriously consider this old school kit:

The description even mentions the annoying factory menu. Looks like a very complete
kit & a decent price.
