PAC TR-4 Remote Turn-on Module , Black

Very small so easy to fit behind the dash, clear instructions, worked as described using speaker wire as the trigger. Just one note: The 6 volts DC that is present between the speaker output on the factory stereo and ground stays on for about 30 seconds after the radio goes off. Also it will turn back on when remotely unlocking the doors. It will turn back off again though if you don't start the car. This has not caused any problem and seems to be normal operation of CAN-BUS systems in newer vehicles.

This was purchased due to researching the audio upgrade in a 2011 C6 Corvette with the Alpine iLX-W650 head unit. Due to the Vette parking brake on the operating performance on the Alpine iLX-W650 head unit, this chip will send a signal allowing head unit to work to its best performance without moving the park brake lever up and down numerous times. This was soldered into the Alpine iLX-W650 head unit harness and not on the Corvette parking brake wires. This is just to keep the issue pretty clear!!!

This is NOT for bypassing your car radio's parking brake restrictions. It is only made to look like one, and that's why the listing's details are vague. The device it is pretending to be is no longer available on this platform.

Used this when the amp wire wasn't working for my head-unit so that i could use another acc power.Works exactly as it should, my subwoofer doesn't pop when i turn on the truck.Note one thing for me: It does not reset instantly. So if you turn it on and turn the signal off and then back on again it quickly, it will not time delay. This is due to its design which is how any delay using a capacitor is going to work.

Does work but will cut off with high speaker voltage. Ended up just getting signal power from the cigarette lighter but might find use for this one day. Recommend for non car audio applications.

It states that the green wire should be attached to low voltage speaker wire, I hoped it would work to allow remote-on wire from aftermarket pioneer head unit to turn on multiple audio components. I hooked up to amplifiers (2), an electronic crossover, and 12 volt power block with digital voltage display to blue wire and it worked (so fare so good). I never knew that a remote out wire should really only be used for one remote-on audio comp. so this is new to me, glad I found it. I made a relay but felt it was a bit wonky and possible source of noise in system.

When you want to bypass your parking brake on your andriod auto stereo it is a must works great would definitely recommend!

As other reviewers have noted, this product did not work to bypass the parking brake signal on a brand new Pioneer AVH-2550NEX stereo that was purchased from Crutchfield. After watching some youtube videos of the product being installed and working on a Pioneer deck i ordered it from Amazon. Unfortunately the product did not bypass the parking brake signal and so will not display DVDs. I just went with the switch option. Returned this product within the return window and Amazon gave me my money back.
