Default Cable routing through LHS front frame near firewall

My project car (‘89 S4) disassembly photos are lacking in a few areas and this is one. The LHS front frame near the firewall has several routing holes and I don’t have a photo showing which cable is routed through which hole. I’ve labeled them A-D below, with an additional blind hole being labeled ???. Any help with the correct cable routing would be greatly appreciated.

Do these holes go into the wheel well or the cockpit? The left wheel well has the Cruise Control in that area.

The pictured routing holes are between the wheel well and the engine compartment near firewall on the LHS.

If I'm seeing things correctly (always a risk), the firewall is on the left side of that picture, and the front of the engine bay is on the right.

I can get you a picture of my engine bay later today, if that would help.

Cheers

yes thats a better perspective, thanks
the top hole ??? looks like a rubber plug goes to it,
looks like A it could be a harness.

the big hole C should be the vacuum lines for the tank and the flappy source.

The other lower hole B could be for the cruise control cable, again the rubber grommet will tell you.
The bottom hole D is for the brake line and the ABS and brake pad sensor

NOTE you should be able to tell when you fit the vacuum lines,
as you probably removed them with the rubber grommets.

thanks Mrmerlin. That helps clarify things considerably. The blind hole I’ve labeled ??? is a mystery still. I’m calling it a blind hole but I haven’t chased it to see if it emerges someplace else and it’s just been too long since disassembly.

Working on my A arm, had to pull the splash shield, her is a 87 drivers side.


Looking back

I think these are your holes.

awesome, thanks DHS928! Those are indeed the holes. I can see which hole/grommet has the vacuum lines.
