I have a 2010 GSR, I'm installing the AMS 600hp fuel system power line. I had it was hooked up to the battery in the rear of the car which there is a problem with that The dealer giving it bull over that seeing the wire is not a factory wire so, I was going to run it stealth to the fuse box in the engine bay.

I noticed there was a extra wire there with no fuse that I think is used for diesel car's picture below. I was thinking if it even is power ? I haven't checked it out yet, has anyone input on this?

 

if its a source of power then rate your wire and fuse accordingly ad you should be fine.

 

Just need to verify with someone who has used this before.

 

what exactly are you looking to verify? a multimeter should be able to tell you everything you need.

 

Got it done looked like no one has tried that before now my wires run stealth no more dealer warrently issues!!
