How-To install PAC TR-7(parking brake bypass) with Alpine touchscreen

I recently bought an Alpine IVA-D300 and, like everyone with a screen, wanted to bypass the parking brake (NOTE: watching videos while driving is ILLEGAL). So i purchased the PAC TR-7 module to do so, but couldn't find a write up on how to do it. This is a very easy installation that can be done before or after the Alpine unit is installed.

Step 1) Purchase a PAC TR-7. you can get them off ebay for around $30

Step 2) Tap the red and black wires into a 12volt source. I just used the positive(red) and negative(black) wires going to the brain

Step 3) From the PAC TR-7, Tap the Green wire to the Alpine Blue remote wire

Step 4) From the PAC TR-7, the BLUE wire to the Alpine foot brake input wire (yellow/black)

Step 5) From the PAC TR-7, the WHITE wire to the Alpine parking
brake input wire (yellow/blue)

There is also an orange and a brown wire on the PAC TR-7, but you will NOT need these wires. The unit will automatically bypass the parking brake and no need to sync anything, just put a movie in and go.

I know this works for the Alpine IVA D300 and D310. The colors to these wires may change with different models but please refer to your paperwork that is included with the Alpine unit to find the correct wires.
