Hey gang - don’t care for the big loom of wires and connectors on the passenger side in the engine bay like everyone else… but I did not want to go the wheel well route. I don’t have pics of the process but do have the final product pic below. It’s pretty straight forward and if you want a cleaner engine bay but don’t want to reroute and drill more holes this is a nice way to clean up the look. Links below on the stuff needed.

Here’s what I did:
1) Pull up the wiring off the body, just to be able to get around it all. There are 3 points where you’ll do this, exposing 3 holes in the metal.
2) Carefully wrap electronic shrink wrap around the batch of wires. Since we’re not cutting or disconnecting the wiring this means the shrink tubing will need to be sliced longways to wrap it around. Doesn’t have to be perfect, and in fact it’ll look butt ugly until step 4.
3) This part is kind of tricky, but you’ll use a few pieces of packing tape to tape the two sides back together (from where you cut it in step 2). These taped areas will be underneath the wiring, so if you don’t want to do step 7 you won’t see the seam in the plastic.
4) Hit it with a heat gun and you’ll see the shrink wrap pull in and actually squeeze the wiring together, reducing its overall circumference. It’ll look like lumpy vacuum-sealed Twizzlers at this point.
5) I repeated steps 2-4 again (with another layer of shrink tubing) to compact the wiring even more and to give it more strength - but I’d say this is optional. It definitely pulled everything in together more for me though.
6) Push the wiring pins back into the 3 holes in the metal.
7) Wrap heat resistant harness loom around the whole thing. Since this stuff is already sliced longways and formed to hold wiring inside it, it goes on pretty easily but does a great job staying put.

Know this may not be for everyone, but since my ride is black it does a decent job looking factory-ish I think. Better than before for sure.

Stuff used (basically what I used… I didn’t use these actual vendors, already had these items on hand):

That looks pretty good
