jvc hand brake cable wire

Hi guys, just did a search and couldn't find anything on my particular unit so here goes. Have a double din JVC KW-AVX800 installed in my 2004 Nissan Frontier. Now, I installed it in my truck, and all is good, except for the correct wiring of the hand brake cable. Now, I want the job to be done properly, and I want the safety feature of the hand brake switch. I read that most units require the ground signal of the cable, but in the manual, it appears as though they wanted it tapped to the positive of the hand brake, (the lead that activates the dash light, in the manual.) I hooked the line up to the wire coming from the hand brake, near it. I thought this would be correct, but the video does not play. Should this more than likely be to the ground of the Hand brake, or is there a different wire in the dash? I can provide the image provided in the manual if necissary. Thanks alot for any help.

Here is what the manual calls for.. Cheers

Not to mention I have done a few of those decks and can say for sure that it is a basic neg trigger for the ebrake wire, hence hooking up to the wire comming straight off the ebrake switch in the car is going to work just fine and dandy for youdouble-secret reverse-osmosis speaker-cone-induced high-level interference distortion, Its a killer

Thanks alot for the replies guys. Hmmmm, I hooked it up to the single wire coming from the hand brake. Looking at the link you posted lostissues, the wire I tapped wasn't yellow. I think it was brown with a red stripe/ Maybe the tap did not properly nick one of the wires... I will check that all out. Thanks, I will let you know.
