I know the cars come pre-wired, I now have stock fogs installed on my '73 1.7L, and have a few questions. Should the wires on the front be wired all the way into to foglight bodies? What the factory left is still there, including the rubber grommets so do they wire right through, or should I make connections with the wires coming out of my lights? (does that make sense?) Are all of the correct wires just ready for plug in above the fuse box? My car hasn't been fiddled with, so I have no doubt they will still be there. I bought the bypass wiring kit on eBay so that the fogs will work on the flasher and independently of the headlight switch. Anybody here have comments on that mod? Thanks ahead of time!

To complete my project posted at #16, I removed the bridging jumper wire on the light switch due to the issues described.

For safety, remove the battery ground wire before beginning.

I ended up making the fog light circuit independent from the light switch circuit.

Disconnect the black/blue source wire from the fog light switch (E7) and zip-tie the wire to the other fog light wires to isolate it (ID it with tape for future owners). BTW, the black/blue wire is the same wire on term. 56 of the light switch that previous docs suggest snipping and piggybacking onto term. K (on my switch).

Not wanting to cut any factory wires, I left the light switch harness intact. Instead, install a new source circuit from the fuse box directly to the fog light switch. I selected fuse no. 2 (source for voltage to the emergency flasher - constant 12V). Route and attach the new wire to the circuit side of the fuse with a piggyback connector. Since this is merely a control wire for the fog light relay, can be small gauge wire (16-18 ga.).

Route and attach the other wire end with a female spade connector to the now-disconnected fog light male spade connector. Reinstall battery ground cable, then test and confirm before reinstalling fog lamp switch and fuse box (removed for access).

Results:
Factory light switch wire harness not disturbed
Fog lights operational w/Ign. ON or OFF, headlights ON or OFF, UP or DOWN, running lights ON or OFF
Factory wires left intact (except existing fog light source wire disconnected and isolated)
