HU harness to vehicle interace harness question

[uturn68]

hey everyone, long time lurker first time poster. i recently bought a jvc kw-ab70bt HU, Pac radiopro 4 harness, and a parking brake bypass from ebay. the instructions for the PAC and the bypass are saying connect the blue/white a blue respectively to the rem. wire on the jvc harness.i believe this is canbus related so the evic ('12 dodge challenger) can display radio on/off. if I do this, is my only option then to run remote from a fuse in the trunk? thanks in advance.

No...you can run a second wire from the radio's remote to an amp.

thanks for the reply canaan, is there a clean/safe way to do this? my rem out is only rated for 200mA and im not sure what the factory display side would be pulling + 2 amps. I bought a relay to run the 2 amps before i realized the interface harness needed my rem off the HU

Then use the relay off the remote and run the relay output to the amp an interface.
