Default UCF20 LS400 Brake Master Cylinder, Which is Front/Rear?

I'm doing my ABS delete and Hydro E brake install this Saturday, I was wondering which line off the master is for the front and which is for the rear?

I've looked around and haven't found any information on it.

It's not clear from the exploded diagram,both pipes from the master cylinder go to the ABS block and the brake line distribution is done from there.

Well on my previous car Nissan 240sx S13, It has 3 fittings, Front/Middle/Rear. Front and Middle each went to a different front wheel and the rear went to a T fitting in the rear of the car. So I'm assuming that the front of the master would go to the front and the rear goes to the rear. If it doesn't work I'm just going to switch it around.

I've never worked on these master cylinders (Never even looked at it) but in the old days on my older cars, (70s & 80s) the front pool, was for the rear brakes and the rear, which had the bigger pool, was for the front.

I have confirmed that the fitting closest to the front of the car goes to the rear, and the other is for the fronts.

Its for a hydraulic handbrake to lock the rear wheels. I can control the pressure to minimize the amount of lock to my preference. But I was mostly looking to do an ABS delete, as ABS sucks...
