1974 Valiant Scamp, timing retarding when revved

Well the car is back up and running. I finished rewrapping and looming the engine bay portion of the wiring harness. I also did a fleet bypass. 2AWG wire from alternator stud to the battery directly, 2AWG from battery to starter directly, then a 4AWG to the relay, and a 4AWG to a distribution block I added in and fused which connects to the ammeter bypass. Voltage is a lot more consistent, and the headlights are 10 times brighter than they were. I ordered a completely new distributor as it has been one thing after another with this current one. The pickup coil connector ripped in half...from an old splice that was apparently done. I cut it out and respliced, but I imagine that the splice is adding resistance that shouldn't be there and the vacuum pot looks ancient, though it works.

Once the new distributor gets here I'll drop it in and retime the car, however at the moment I have no turn signals. They were working fine after putting in the new harness when I first ran the car but after fuse #7 popped (20amp) I lost brake lights, turn signals, and the dash "Test" lights that come on before you start the car. I'm guessing something in the column is not happy.

I replaced the fuse and brake lights as well as the dome light work again, but I have no hazards or flashers. Likely turn signal switch damage from dropping the column and removing the cluster?

I also noticed the stock wiring is routed extremely poorly. It's hard to believe this is factory wiring , so much bare wire and nearby sharp edges.

ON THE PLUS SIDE, my AC/Heater blower is working now. There was a two wire grommet above the brake booster with one brown and one tan wire, neither of which matched any FSM for AC wiring, but that was it. Brown to green on the blower, and tan to dark blue on the engine disconnect harness. However the compressor is not kicking on so I'll need to check the fill level on the R12.
