Greetings! For the folks that have moved their fuel pumps to the front of their cars, what is the best method for relocating the pump electrical wiring? I am having trouble finding a thread that addresses this. Thanks!

As Jeff Bowlsby pointed out to me, Porsche increased the fuel pump wire to 12 gauge when they relocated the pump. I replaced the original pump wire by running a new 12g red/blk wire from the connector on the relay board all the way to the new pump location. I also ran a new 12g brown ground wire from the left headlight ground post to the new pump location. There is a closer ground post below the air box up front but I wanted to integrate the new wire in the main harness and the left headlight bucket made more sense. It doesn't HAVE to be done that way, but that's what I did to keep the factory wiring schematic accurate and using the appropriately sized wire to accommodate the longer wire run. I had the harness out of the car though so kind of cheating.
