[QUOTE="Deiimos, post: 8811617, member: 682903"] If that is the case and it is like the older Pioneer’s, then you need the relay to have a “delayed turn on”. Meaning once the head unit powers on, you need the relay to wait a certain amount of time before it turns itself on, which then sends the ground signal to the parking brake wire. How long the Jensen needs, don't really know until tested I guess, unless you can find someone that has done it for sure. When I tested my Pioneer, I found that roughly 10 seconds was enough to guarantee it worked every time, so that is what I aimed for when building the bypass. Only a few seconds after the head unit started was not enough on the Pioneer, it would still give the warning that it would not play video. [/QUOTE]
