Ok, so I did a search for this topic(to no avail) and did not see it in the How-to or stickys, so I thought I would take a stab at my first write up. To start off, the truck I'm working on is a 1984 F150 4x4 base model, with a 4.9 inline-six and 4-speed manual transmission. After fighting with intermittent running lights and turn signals I finally tracked down the culprits; a bad drivers side signal socket, as well as a bad turn signal switch. The combination of the two made troubleshooting a nightmare. Once I got the wiring squared away, and replaced the turn signal switch under the steering wheel, I headed to the local pick n pull for some parts. Since my truck has never had a horn that was going to be my first stop. I found a 2004 F150 that had most of the front end already pulled off leaving the horns and associated wiring easily accessible, so I got to work. As I was unbolting the horns I noticed that the turn signal socket looked almost identical to the one I had to replace in my 84, so I cut it out and headed over to a 1986 that was two trucks down to see if it would fit into the original housing. It was a drop-in replacement so went I back and grabbed the other side as well. Here are what they look like side by side.
Here is how it fits in the 1984 housing.
The wiring colors are the same as well. BRN(+) BLK(-) GN/W (signal). On the passenger side the signal wire is W/LB.
Finally, all my lights, blinkers and flasher work consistently. Plus now I have a "get moving" button lol. The whole set up(2 new housings, 2 sockets, 2 bulbs, and 2 horns) cost $20 because I had spools of wire and a relay for the horn already. I even went back the next day to snag the wiring for the brake lights and back up lights so all of my lights are the modern bulbs (3156/3157). The brake light sockets are also a direct drop-in for the original housings, but the 2004 back up lights need one of the tabs snipped off to fit. This forum has helped me immensely with the issues I've had with my truck so I hope this helps someone in a similar situation.

You sir, are a hero. I would have never considered looking at newer models to scavenge parts like these. I'm lucky enough to have plenty of bullnose and newer Ford trucks at the LKQ's here in South Carolina near me. I'll add these to my shopping list for my weekend run.
I'm glad this helped someone. Like I said this forum has been invaluable for me so I'm just trying to pay it forward. Not only are they finally reliable, but they are also way brighter. Cheers!
