Won't be able to get pics for a while, my car is being collected tomorrow to go to abbey
My alpine headunit had - Bose loom > Pac > speaker harness > alpine loom & it worked fine for 3 years.
Everything works on my new unit except the sound, but with a multimeter on the ignition feed from the bose to the pac it reads as 0 but between the other side of the pac I get a reading fine from there
