Wiring ...

 

+1 on rreitz. Get a voltage meter that test continuity and make sure the wiring is, well, continuous. With the light switch turned on, put one probe on the far end of the wire, then poke it along the way 'til the meter doesn't beep. Wires might look good on the outside, but they do corrode on the inside and lose connectivity.

 

Using a Ford shop manual and volt meter, follow the 12 volt line at h/l switch for rh side parking light.
Measure at switch, then connector coming thru firewall, then at light housing.

Where do you loose 12 volt reading?

FYI, parking light (running light) not going thru t/s switch.

 

If you look at the wiring diagram for the parking lights, you can see that power for both comes from the light switch on one wire (#11). At the connector for the drivers' side light harness, it splits off and sends power over to the passengers' side. I would investigate that length of wire between the two light harness connectors.

 

Thanks guys!!!! Sometimes there is no substitute for hand over hand tracing. Found the cut wire behind the passenger headlight bucket. replaced that section and Voila! Lights!

You guys are AWESOME!

 

Awesome!!!! Congrats.
Sometimes it's just good old detective work and not throwing $$$ at a problem. Electrical issues in these cars not that bad.

Just help solve similar one for my neighbors 67 FB.
All lights worked excepted left front blinker & left dash blinker indicator on instrument cluster. Strange.

Looking at Ford shop manual, those two separate wires/circuits meet at bottom of steering wheel column into one pin at the column connector. Told him to look at it. Sure enough, the pin was popped out of the connector. Bingo.

 

for next time instead of poking wires which imo causes more harm then good

invest in a tone generator. Its a little handheld device then sends a dial tone through the wire and you trace it with a probe hooked to an ear piece

very easy and very fast an you dont have to unwind the harness until you have to

check harbor freight and amazon. prob around $65-75 or so

I had mine about 30 years all I did was palm the cable guy $10 and there it was on my work bench.
