Place yourself in the driver's seat looking forward. There is a socket at the bottom right hand side of the headlight bracket, flush with the mudguard/ fender. The electrical cable, in a protected piping, extends to the extreme right edge of the fender, then turns at right angles rearwards along the edge of the fender to where the fender meets the glacis. Now here is where the pictures are not clear. Either the cable enters through a small hole in the glacis at this point, or it makes a sharp downwards turn through a hole in the fender ( at this same point) and enters the tank through a hole in the side somewhere above and a little behind the drive sprocket. I'm inclined to go with the latter possibility. My resources are a Panther G at Bovington in 'Panther in Action' by Squadron, and 'Panther' by Concord. On the cover of the Squadron publication is an artwork of Panther G with the cable clearly disappearing into the top surface of the glacis following a straight line after exiting the light bracket, but I haven't seen any photos to re-inforce this illustration. I hope my description helps you and is not confusing.
