Line lock to rear brakes??

[1jzzpowered]

Hello guys
I am trying to install line lock on my soarer 1jz.
It is without abs.
I have 3 ports.
2 for each of the front wheels, and one port going to the rear weels.
I would like to install the line lock on the rear brakes, so i can press the button, and controlling my burnout with the front wheels..
Unfortunately it don't work.
I unpluged the rear port and connected it to the output port of the line lock.
New line was putted from the master cylinder unplugged port to the input port of the line lock..
And the result:
When i don't apply brakes and pressing the swith to activate it and close the rear circuit it wont work...
When press the brakes few time, and apply the line lock button, it block the rear wheels..
Where is the problem?
Anyone with idea?
Or i can be used only on the front brakes?

Okay.
I resolved the issue.
If someone want ro install line lock on the rear brakes, to smash the button then control with the front brakes the burnout
You must install in reversed.
What i mean.
By default the line lock have one input and 3 output ports.
This is okay to follow if you install it on the front brakes, but on the rear it don't work.
So the solution
From the master cylinder where the rear wheels are attached you connect this to the output portbof the linelock.
The rear wheels line must be connected to the input port of the linelock
That's the solution of linelock on the rear wheels
