Still just slowly working through the new-to-me 914 and I'm finding just a few little niggles that provide me an opportunity to "fix" things but this is a head-scratcher.

There is a wire obviously run by a PO that starts down behind the center console, runs to the drivers side and out to the frunk - back across under the fresh air blower and terminates as a connection to the mounting bolt for the washer bottle.

Short story - it grounds the fuel pump.

Could it have something to do with a fuel pump relocation to the front and can anyone tell me why I shouldn't shorten it up and at least connect it to a good solid ground under the dash?

Can be grounded to any good near by body ground as long as its clean and paint free under the connection.
Someone in the past just made it harder that it needs to be,cheers.

There is a ground tab down under the brake fluid tank for this purpose (at least on a 76)

Yup. That's where mine gets its ground.

Thanks folks. I’ll get that moved ASAP. Back in the garage until I can get back to it in a few weeks.

On my '74 biturbo with 2 fuel pumps (front & rear), I made a simple (new ) ground connection to the front trunk floor area...works perfect.
