Red face HELP - ACC Line in the Trunk SAM - C320

Hi everyone,

I searched the entire forum and I couldn't find if there is a ACC terminal on rear SAM. I need the ACC line to power small camera in the trunk, and I do not want to disassemble the front and tap into cig. lighter if I do not have to. I found on one of the threads that there might be an ACC line on the SAM, but I can't find the diagram or a picture of a rear SAM anywhere. HELP

( Fuse 7 )
Its empty but place a 10amp fuse inside it. With the wire inside..

I use it to power on my subwoofer amp

Power turns on when key is place into and turned on to the second position

Fuse 16 also works. That's normally reserved for voice control and phone.

Thanks for the info to both of you. I will check Fuse 7, and since I have voice control and bluetooth I don't think I can use 16. Do you by any chance know what fuse 7 is for. The fuse chart doesn't even list it

Fuse 7 will work perfectly fine.. Im currently using it now.. There is no fuse nor anything on the list for it because its a free 12volt power =D

I would not use fuse 16.. Even if you don't have those items your still running power on those cables.

Thanks Xhale707. I just have a follow up question. What did you use for ground? Also just to make sure the fuse 7 is ACC line (meaning the power is on only when the key is turned)

Thanks again
