What did you do to your C5 today? (2)
The first thing I did was with the Key still in after I pulled it out of the garage was remove Fuse #23 in the inside of the car. This is for the Body Control Module as well as the Steering Column Lock Relay. This is a crucial step.

Then I disconnected the Battery.
I pulled all the Cover Panels out of the way and found the Steering Column Lock Relay. Isolated that out of the wiring clipped the two wires going toward the Steering Column and capped them off with heat shrink, tucked them off up in the wiring harness. The power wire going into the Relay I found in the harness, clipped that and double capped it with heat shrink then tucked it back up in the harness. I put a zip tie up in that area so it's nice and secure. Taped up the wiring up in that area and brought the tape down below the cover enough so when I install the LMC5 Module I can clean it up real nice.
I pulled down the Relay Connector as far as I needed to at the moment to install everything later, there is still one more wire according to the Schematic that's going to get clipped, capped, and tucked up. Then I'll tape everything up nice. That Relay looks the same as the Starter Relay next to it so there's a good one for a spare. It'll look good when it's done.

Put the Fuse back in, connected the Battery Car turned on and pulled back in the garage without an issue, definitely all kinds of Service Column Lock and Pull Key, Wait 10 Sec messages. Pretty sure it'll drive fine since I tuned out the Fuel Shut Off I haven't driven it out of my driveway yet, I'll do that another day. Definitely different not hearing the Column Lock Motor anymore.

Relay and wiring removed, small Module installed in it's place is a win to me instead of having the factory Relay there to activate an inline box. That's extra crap to go wrong.
What I did is next level, most won't go that route. Slight OCD I don't want useless **** in the car and I have some wiring knowledge.

I also got the trunk panel installed and covered back up with carpet.

I think better (worse?) is when you get all your bends and flare perfect, ******* minty fresh- and the nut is on the wrong side of the bends and can't be fished down lmao. Talk about "time for a beer and a nap"
After what I did yesterday with that wiring laying in the position I was with that car on the ground I had a couple drinks before I went to bed.










First I started "CAD" cardboard-aided design to determine the sizing of the cubby. No useful pics of that process.
Then with CAD computer-aided design I developed a proper 3D model. Space is tight with this sub so modeling everything has helped me:
- Ensure adequate internal clearance for the subwoofer
- Determine interior volume: sub is rated for a sealed enclosure of 0.3ft^3, and I nailed it @ 0.31ft^3
- Create template drawings for easy cutting and pilot drilling in 1/2" MDF
The lower rectangular portion sits in the cubby and is hidden while the upper triangular portion sits on top of the trunk carpet.
