1964 Plymouth Valiant Wiring Harness Build/ Questions
Hello everyone,
I'm currently rebuilding a engine side wiring harness for a 1964 Plymouth Valiant and just had a couple of questions and wanted to take some advice and insight from those more knowledgeable than I am.
------------------------------------------------------------------------------------------------
-Milspec M22759/16 wiring
-TechFlex Insultherm braided shielding
-Tessa Tape 51036
-Permatex Liquid Electrical Tape
-3m high temp ring terminals used where it was possible
-rest are tin coated brass terminals
-Klein Tool Open Barrel Crimper
-Klein Ratcheting Crimper
-Irwin Wire Stripper
-No name wire stripper
-No name wire cutters
10 gauge black - alternator ring
16 gauge green - alternator packard 56 1 pin
16 gauge purple - coolant temp sensor
12 gauge blue - coil wire to resistor
12-12 gauge blue / brown - double resistor connector top
14-16 gauge blue / blue - double resistor connector bottom
** gauge blue - ignition relay top
16 gauge green - ignition relay bottom
(I need to double check these gauges but I think these are what I used)
------------------------------------------------------------------------------------------------
I had a few questions regarding the safety of the harness and just wanted some insight if anybody has any. My concerns are the following:
The starter harness of only two wires used to loop from the starter relay all the way around the front of the block and then back down towards the firewall. I thought this was ridiculous and an unnecessary path. I shortened it to go directly from the starter relay to the starter. Additionally, the wires that were originally there were already replaced with something not stock. Best I could measure, the black wire (OEM red and since chanced to red) was a 10 gauge wire, and the brown THAT WAS THERE ORIGINALLY was falling between a 10 and 12. 12 was a little bit too tight and it fell easily out of the 10 gauge in my wire gauge measuring tool, and the black 10 was definitely a 10 gauge without doubt.
Because of this, I did a little digging in the forums. Again, best I could find, people are saying you should be running AT LEAST a 10 gauge red wire from the starter, and at LEAST a 12 gauge wire for the smaller diameter brown wire. There are some saying they step up to a 8 gauge red and 10 gauge brown. PLEASE let me know your thoughts.
Additionally I think I'm keeping the ammeter for now, and if I am, this small harness is NOT where I would want to put a larger fuse correct? I would want that between the small 10gauge red wire that connects from the starter relay lower ring terminal to the firewall connector? I ask about this routing specifically as it is what Painless is listing in their Mopar 21circuit custom harness installation instructions. Again just wanting to confirm.
