NOTE: The solution below will work and uses "off the shelf" parts. However, a fellow board member and Z1 enthusiast has developed an ALL IN ONE solution for forum members at a much cheaper price than 2 -TR7's and works with or without autoheadlights. I recommend this solution over the instructions below as there is no programming, it's cheaper, it works with all types of illumination/dimmer wires, and it's designed solely for this purpose. For more information and instructions on how to order please review this thread:

Hey guys, just wrote this up, hope it helps some of you out. Below are instructions on how to use one tr7 to bypass z1 security or 2 tr7's to bypass security with autoheadlights.
Difficulty:
Wiring - Moderate
Programming - Easy
Programming a PAC-TR7 to bypass AVIC-Z1 motion security
FYI, the following will work even if your parking brake, speed sense and GPS is all attached properly. You do not need to defeat these systems for this bypass to work.
Make sure your PAC-TR7 is revision 1.1.2 or greater! The ONLY way to tell if it is 1.1.2 or greater is by looking at the bottom left hand corner of the instructions that came with your PAC unit. It will say something like “SW 1.2.4.”
IF at ANY point you mess up during this process unhook the red power line, turn your PAC switch off and then back on, reattach power and start over. READ THE ENTIRE INSTRUCTION SET before starting. You have to be pretty quick, and if you wait too long between steps you have to start over.
Take your pac out and strip the leads, make sure none of the leads touch each other.
Turn the switch to your PAC ON.
Attach the black lead to ground and the red lead to an unswitched positive source.
Touch the brown wire to ground (wherever the black wire is hooked up will do) 17 times. You will see the red light flash every time you touch.
Wait 3 seconds
The red light on the PAC should now flash 17 times, MAKE SURE it flashes 17 times.
Touch brown to ground once
Wait 3 seconds for the red light to flash quickly for a second.
Wait 3 more seconds for the red light to flash 2 sets of light flashes quickly
Wait 3 more seconds for the red light to flash 3 sets of light flashes quickly
Touch the brown wire to ground 5 times.
Confirm the red light flashes 5 times
Wait 3 seconds for the light to flash 4 sets of light flashes quickly followed by rapidly flashing lights.
You have now completed programming. You have just programmed your PAC-TR7 to pulse once after 5 seconds when on a constant trigger. Now TURN OFF the PAC-TR7 switch.
Wiring:
Attach the red wire to either constant + or switched +, it doesn’t matter which, I'd recommend switched. Attach black to ground. Attach BLUE to your Z1 dimmer wire, I highly suggest putting a diode inline to allow electricity to only flow towards the HU.
Attach Green to Z1's amp turn on wire.
That’s it your done. Upon starting your car your TR7 will send a + pulse to your HU between 5-6 seconds after the the amp turn on wire turns on which should be timed properly to unlock your Z1.
AUTOHEADLIGHTS WORKAROUND
If you want your dimmer wire to function properly (ie dim the HU at night) and you have auto headlights or don’t want to wait 7 seconds to turn your headlights on (if you have autolights at night and/or your headlights turn on BEFORE the TR7 pulses the trick WILL NOT WORK without performing the steps below) here’s what you do.
First off you will need ANOTHER TR7. Program the first one as stated above. Program the second one as follows:
IF at ANY point you mess up during this process unhook the red power line, turn your PAC switch off and then back on, reattach power and start over. READ THE ENTIRE INSTRUCTION SET before starting. You have to be pretty quick, and if you wait too long between steps you have to start over.
Take your pac out and strip the leads, make sure none of the leads touch each other.
Turn the switch to your PAC ON.
Attach the black lead to ground and the red lead to an unswitched positive source.
Touch the brown wire to ground (wherever the black wire is hooked up will do) 12 times. You will see the red light flash every time you touch.
Wait 3 seconds
The red light on the PAC should now flash 12 times, MAKE SURE it flashes 12 times.
Now ground the brown wire once
Wait 3 seconds
Confirm the light blinks once
Ground the brown wire again once
Wait 3 seconds
Confirm the light blinks once
Wait 3 seconds
Ground the brown wire once again
Wait 3 seconds
Confirm the light blinks once
Ground the brown wire once
The light will let out 1 quick burst of light flashing
Wait 3 seconds
The light will let out 2 quick bursts of light flashes
Touch the ground wire twice
Wait 3 seconds
Confirm the light blinks twice
The light will let out 3 quick bursts of light flashes
Wait 3 seconds
The light will let out 4 quick bursts of light flashes
Ground the brown wire once
The light will let out 1 quick burst of light flashing
Wait 3 seconds
The light will let out 2 quick bursts of light flashes
Touch the ground wire twice
Wait 3 seconds
Confirm the light blinks twice
The light will let out 3 quick bursts of light flashes
Wait 3 seconds
The light will let out 4 quick bursts of light flashes
Ground the brown wire once
The light will let out 1 quick burst of light flashing
Wait 3 seconds
The light will let out 2 quick bursts of light flashes
Touch the ground wire twice
Wait 3 seconds
Confirm the light blinks twice
The light will let out 3 quick bursts of light flashes
Wait 3 seconds
The light will let out 4 quick bursts of light flashes
The unit will now flash the light quickly. Programming is complete.
What you have just done is programmed the output to delay turning on for 20 seconds. The steps above actually have you turn on this timer on all 3 outputs when you really only need it on the first one. But since you have to program all 3 timers anyway I figured might as well program them all for 20 seconds, it doesn’t hurt anything.
Turn the switch to the PAC OFF and wire as follows:
Attach the red wire to switched positive, I'd recommend the red wire off the Z1. (TR7 current draw is minimal). Attach black to ground. Attach BLUE to your Z1 dimmer wire, I highly suggest putting a diode inline to allow electricity to only flow towards the HU.
Attach the green wire to the cars factory dimmer wire.
If wired properly you should have the following scenario:
Black wires from both TR7’s are going to chassis ground.
Red wires from both TR7’s are going to switched positive.
Blue wires from both TR7’s are going to Z1 dimmer wire with diode inline (do not connect – side [unstriped] of diode’s together!)
Green wire from 5 second pulse programming is going to Z1 amp turn on wire
Green wire from 20 second delay programming is going to car dimmer wire - I've personally put a diode on this wire too
Basically what will happen is if you start your car at night, your lights will automatically come on, however the dimmer wire on the Z1 will not get the signal to dim the display for 20 seconds. Before that 20 seconds is up your first TR7 module will send a pulse to the dimmer wire to disable security features.
Good luck and post in this thread with questions.
