Anything unusual on the S4 wiring to be aware of?

If you are not looking for originality it makes sense to update the wiring with ample fuses and relays throughout, as others have noted. There are a number of previous posts that you can refer to that have updated wiring diagrams to help you organize the wiring.

I went that route, as well as using an RTMR (Rear Terminal Mini Fuse and Relay panel) to make things tidy, compact, and isolated from heat/dirt as shown below. I located the RTMR near the vehicle plate on left side of the engine bay. I had originally implemented fuse blocks on the firewall but it looked unkempt to me.

An overall (battery, alternator, ..) cutoff kill switch is also good for peace of mind. I placed mine on the rear panel, easy to reach.
