Chvw3c steering wheel harness -battery drain???

[malaw78]

Hey guys!
Just wanted to know if anyone has used/ knows of this harness and if it might cause battery drain? The guy at auto barn where I bought it said I would have no issues and it was plug n play but I just wanted to double check on here to see if it really was? I tried looking on the aerpro website for more info about it but found nothing, so I’m not sure if I had to cut the “acc” wire in the harness and hardwire it into the side fuse panel with a fuse piggyback lead to run a aftermarket h/u (kenwood)
Any help would be appreciated and thanks!

Maybe ring Aerpro? I have found they are pretty good on customer support.
