I'd really appreciate that, TF. That switch bank looks like it would work perfectly. Do they typically have a master harness feeding into the back? Or does each switch have its own plug?

That sounds great, Tinkeringfox. Do you know if Tundaman's switch bank would work in my application? I can easily wait a few weeks to a month for instructions, but as I reside in Northern Canada and work a 24 day/4 day off shift, I would like to try and get parts ordered up as soon as possible to allow me to make full use of days off. Several items such as my cold air intake can take up to a month to get ordered in.

I have to say, guys.. I'm really impressed how well you guys did. I have a '17 GMC 2500 6.0L that I use as a work truck. SLE package with just three toggles - traction control, cargo lights, and hill assist. I need to wire in a few more controls, such as a master control for a slip tank, light bar, and additional cargo lights. It looks like Tundaman's switch bank would work perfect for my needs. Would it be compatible with a gas truck? (The exhaust brake being used by hill assist). I'm a bit of an amateur when it comes to wiring, but if Tundaman, smcgillis10, or Azelkhunter would be willing to spend some time walking me through the purchasing of parts, setting up, and troubleshooting - I'd be more than happy to compensate either of you.
