Line lock

It will work just fine by adding it into the front brake line just about anywhere you want it.
With mine I just used the steel compression unions that are tech acceptable and legal, cut the line and routed it into the line lock.
No extra lines or fittings were used as one end of the compression union is the same thread as the line lock accepts.
I did have to seal them into the line lock though, because neither thread was a pipe thread but it was well worth the outcome.

You will need to consider the brake lights also, because legally the brake lights need to come on and stay on while the lock is active.
I dealt with this in a very unique way, so when you are ready to get on it let me know and I can simplify that for you. :-) so don't end up buying another brake switch for the fronts.
