72 duster firewall wiring questions ???

All the under hood is done. Alternator charging wire ran back and landed on positive terminal of starter relay with 14 ga fusible link @ the relay end. Red feed wire ran into interior cockpit through bulkhead with a 16 ga fusible link at the stater relay end. Blue wire underhood cut loose at 3 way splice and new 14 gauge
Wire ran through bulkhead into cockpit. Will remove instrument cluster tomorrow night to get access to the back of the ammeter and the ignition switch. I have been taking some pictures along the way. Pretty amazed how intact the wiring is on this old girl. Taking my time soldering and heat shrinking everything I get into in order to preserve all the originality that I can. Planning to install a 10 amp relay behind the instrument cluster somewhere to power the switched 12V ignition source for the new autometer dash. Thanks again and I will update this post as I go!
