Been watching this...

 

And I have this...

http://cgi.ebay.com/PIONEER-DVD-BRAKE-BYPASS-HACK-AVH-P5200BT-AVH-P5200DVD_W0QQitemZ130369230584QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item1e5a9c96f8#ht_717wt_1165

 

and have been trying to figure out how to get it all set up properly. Im trying to have it all down in my head before I go tearing the HU out to get at the wiring.

 

My questions are...

[*]Is it necessary to disconnect the battery first?

[*]What changes if I have amps hooked up? Anything?

 

The directions on the bypass say to...

[*]hook the blue wire to the remote turn on wire on Pioneer HU (blue with white)

[*]hook the black wire to ground wire on Pioneer HU (black)

[*]hook the green wire to the brake wire on Pioneer HU (light green)

 

The headunit is already installed, so what do I do with the current connections? I would assume the remote turn on wire is currently connected to a wire running the amps etc. right? So do I just disconnect it and ONLY connect the relay and the remote turn on wire on the HU? Wont that eliminate the amp turn on?

 

As you can tell, I did not do the HU install myself but would like to get this relay setup. Any insight or direction would be greatly appreciated. Thanks!

The blue/white wire (REMOTE TURN ON) on the head unit needs to power up the by-pass relay as well as turn on the aftermarket amps.
