This is my first post so I'll try my best. I have a 49/50 F-1 that has a toggle switch under the dash to the left of the steering wheel I was wondering if that was factory or added later. Also I would like to restore this truck back to original and was wanting to know if anyone makes an authentic looking wiring harness.
Well with the truck being 60 years old and probably modified a few times, there's no telling. Switch and **** additions by various Previous Owners is almost a given.
HOWEVER, there was a factory installed toggle switch on the 48-50s in the location you describe that was used to turn on the instrument lights.
There are lots of folks who make OEM style wiring harnesses. Try Mid Fiftys:
I would guess that someone added it on and its not factory. Its very common for people to add on fog lights, worklights, etc. Take a look at the wiring and terminations, if its a factory Ford thing then the wiring to the switch would probably be cloth covered and have nice factory looking terminations. If it doesn't have cloth covered wiring or has those cheesy crimp on style connectors with the ugly plastic sheaths (blue, red, or yellow)) then someone added it.
On all the 48-50 trucks that I've seen the intrument lights have been controlled through the standard headlight switch, but, with Ford, anything is possible.
Yes, there are a couple of companies that make a factory style harness. They are a bit pricey. What are your plans for the truck? are you planning a all original style restoration or just trying to upgrade it and make a decent driver? If you aren't going for an original style restoration then there are numerous choices for harnesses. I used a 21 circuit harness from EZ Wiring that I picked up for $150.
I just saw the under-dash switch for courtesy lights somewhere on here this week; first I've heard of it. None of the diagrams I've collected show it. Coincidentally, while working on my truck this week I decided I need a switch to shut them off while I have the doors open...
The instrument light switch I was speaking of is on this wiring diagram in the upper left corner, third item down (about 2 inches) marked "Instrument Light Switch"
Shop Manual schematic shows it seperate for 1950 as well, but it's possible they changed it in mid 1950 with a number of other items.
I get it now, I guess I need to read more carefully. Why on earth would you want to turn off your instrument lights? Even modern trucks have a courtesy light kill switch, so you can leave your doors open and play real loud mariachi music at a work site.

About the only reason I can think of is if you were out driving in the corn fields or somethng and they interfered with your night vision, preventing your eyes from adjusting to the darkness out there. Also, when I was driving between School in Central Oregon and San Diego in my 55, I would turn off the instrument lights while driving at night and it really reduced eye fatigue as well. But as previously mentioned, in the 55s you did that with the headlight switch rheostat. I believe you can still do that in modern cars too - I can in my 2002 Ranger at least!
LOL, that's funny Ross....Like that little light is going to drain the battery but a 1000 watt stereo playing for 8 hours won't hurt it.
On the toggle Switch, its definitly correct and as Julie mentioned it was to turn on & off the Dash Lights drivers preference in the dark hours.
Back in the day we never had street lamps, hell now with the street lamps you don't even need Head-Lamps to drive at night.
Out in the country where its real dark you could drive with parking lamps.
that switch you are refering to is held in place with 2 machine screws, if you take it out be carefull you don't drop them as they are small.
Also they used the same switch in the Ford Trucks that I know of since 1937 -1950.
It is very correct and has a rectangular cut out where the toggle comes down through the dash.
I've had them on all the '48-50 trucks I've had. Like Julies stated, I think they were to turn off the lights while driving in the dark. Out on the open road they probably figured they didn't need a speedometer at night.
BTW, if you're looking for a replacement switch it's the same as the one used on the Ford 8N tractor for the backward facing spot light on the back left fender, which is sold by most of the 8N parts vendors. I used a switch out of one of my parts trucks to replace the broken on my 8N.
Thank you all very much for the answers. As for what I would like to do with the pickup is a original restoration, this F-1 was bought by my great grandpa new in 49/50 and has never left the family. So anything less than an original restoration just doesn't feel right for one. I'm sure I'll have many more question later like paint colors for all the different part. Once again thank you all very much for the help.
