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.
