I'm sure it's been covered before but I can't find anything using the search feature.
I'm looking for some pictures of the cable routing for the e-brakes. I need to know what the guides look like and where they are mounted because I'll have to buy/make them in the future. The PO used electrical wire for guides on the truck previously.

Now that I have new e-brakes I'd like to install them the correct way.
Thanks for any help.
