V1 Intercooler water pump ground

[PHENDERSON]

I'm in the process of hooking up my fuse box and everything is going great until I come across two wires, 1 red 1 black labeled "intercooler water pump ground". They're in the same general area as the tail light and license plate wires. I watched the old fuse box video and it shows soldering a ground for the radiator fan. Do the new wiring harness videos make the old video obsolete so you no longer need to solder the radiator fan ground to a blue wire in the black fusebox multiplug? I feel like everything is wired up so I can't think of what these 2 wires I have left over are for.

Hmmm...perhaps this was added for TC cars but since mine is SC my pump is already wired. Am I right with this?

I'm in the same situation on my 06 SC Build. I have the same wires, a pink one for the pump power and the red/black for the pump ground. Should I just cap them off and then wrap them into the bundle? I think I may want to find the pink ones power source and clip it off, just to not have power coming in without a release?
I'm too deep in to just delete them completely out.

I cut them to about 3 inches from the main harness and capped them just in case I need them in the future.

Make sure you insulate it well (With electric tape or shrink wrap). It doesn’t need a “release”.

You could also extend it to the dash area in case you want to run ignition on accessories.

I would like to have a power port so I can power my phone to use for Navigation on trips. I was assuming that the purple fog light wires would be used for this.

 

[Gtstorey]

I think the fog light wire had a separate switch, but I'm not sure. You also might decide you want a radio or heated seats/electric vest connection, auxiliary lights etc. I would recommend extending it or marking where it is in the harness in case you need it. As long as you keep it from touching a metal ground it will be fine.

 

[Robinjo]

Understood, thanks.

I have an extra power wire up front as well. I ended up folding them over and taping them up pretty well.

Generally speaking I feel like my engine area is a hot mess, like it's not very well coordinated and everything barely fits. I had to strap my ECU to the side of the fuse box because I couldn't get it to fit in the actual slot. I know it's user error and maybe I'll revisit to clean it up in the future but it would require me to extend nearly every wire in the back. Wondering if anyone else has a similar situation.

I started in the back and worked my way toward the front. Mine could have stood to be a little longer. Everything connected but a little extra length between the BCM and the dash area would have been nice. If my Instrument Cluster connector had been any shorter it would have connected without extending. But again this was more an issue in front of the BCM, not from the fuse box area to the BCM.
