Assistance adding junctions, and general advice.

[Mr Nick]

Over the years I've added a few electrical items to my Cutlass. Least year I added FAST EFI and a radio, and decided it was time to re-visit how everything was wired. Below is a diagram of my Alt / Batt / Horn Relay connections, and all the accessories I've added.



I am currently using 8 ga. amplifier cable from the Alt to Batt, and Horn Relay to Batt. However, I've read this isn't the best option?

What I want to confirm:

• Routing of the charge cables is correct.
• Where to add a junction to positive side for all the accessories (between Alt and Horn Relay, or between Horn Relay and Batt?)
• Depending where the junction ends up, do I run the charge cable to the junction or leave it at Horn Relay?

I'm looking at something like this:

Although something with a cover would look much nicer IMO.
