Hello, new to the forum but I’ve run into a wall (figuratively speaking) I have a 1954 ford crestline Victoria that I have been restoring. The wall I’ve hit is the turn signal junction block. I can not for the life of me figure out how all the wires go back in. Yes, I’ve looked at all the wiring diagrams but still can’t figure it out. My hope is for someone to post a picture of their junction block so I can copy the wiring. Please help and thank you for your help!
Does it have a reproduction wiring harness, and turn signal switch? The wires look in pretty good condition, for being cloth covered. The reason I ask is that it's likely the color codes don't match the original wiring, and you won't get far with this approach. You may end up having to figure out what the wires all go to on the car, and then use an ohm meter to see which wires on the switch connect together in the three positions, and figure it out from there. it's not as hard as it sounds...well, it's hard, but not impossible. I think there's an old thread or two on here that explains it, but searching for this stuff is challenging.
This may be of no help but at least you can have it for later reference. This is the wiring and turn signal switch from the steering column on my '54 Customline. I was having issues with my turn signals too. I don't remember why but, I wound up soldering a wire between terminals 1 and 5 and the turn signals work fine. Oh yeah, car is converted to 12v.
Thanks evintho, but unfortunately that doesn’t help me at all. I have replaced that harness and was able to easily read the diagram on that one.
then just connect like colored wires on both sides of the block...yellow to yellow, green to green, etc. Nothing to it.
Unfortunately I still can’t figure out exactly where they all go. The other side of the block has bower wires and the block itself has some ports that connect and some that don’t. If someone can just take a picture of theirs, I’d be done! Haha I do appreciate your help squirrel!
this is hard to read, please download and save the image, open it in a good image viewing program or app, and zoom in on it. The problem is that turn signals were an option back then, so they show the wires as dashed lines. The colors might match what you have?
This isn’t immediate help, but if you’re doing a restoration, get one of these. You’re a young guy, you can probably get by with the 11x17. I use the big ones even with my reading glasses on. On my 55 bird, all those connections go straight thru. Just like squirrel said. https://classiccarwiring.com/products/1954-ford-cars-color-wiring-wiring-diagram
That’s one of the wiring diagrams I have and I’m still having trouble. I’m sure someone can reach under their dash and just snap a picture…
Get a multimeter and set it on the ohms scale to check for continuity. This is for checking out the switch. With the switch in the OFF position, test for continuity for the wires. There should be 3 that connect. Turn the switch to Left turn and see which of the 3 wires connect. Should eliminate one wire. Now turn on Right turn and test the 3 wires again. There should be one wire that connects in both cases. Label that one as one going to the brake light switch. The other wire that connected in the right turn test goes to the LEFT rear light. The remaining wire goes to the RIGHT rear light. Now onto the rest of the wires. With it switched to left turn, there should be two wires that connect. On right turn, there will be a wire that is common to the left turn test. That one will go to the flasher. The other side of the flasher goes to the ACC side of the ignition switch. The remaining wire with continuity in the left turn goes to the LEFT front turn and the left indicator in the dash. The remaining wire goes to RIGHT front turn. If there is only one dash indicator light, it goes to the third terminal on a 3 wire flasher. Not too hard to do.
This is the info I got from tech support at Rebel Wiring when I rewired/converted to 12 volts on my '54 Ranch Wagon a couple of years ago. The color codes for the turn signal switch are as follows: BLUE TO FLASHER GREEN TO BRAKE LIGHT SWITCH ORANGE-BLUE TO RIGHT REAR TURN GREEN-ORANGE TO LEFT REAR WHITE-BLUE TO RIGHT FRONT and INDICATOR LIGHT GREEN-WHITE TO LEFT FRONT and INDICATOR LIGHT This from FORD PASSENGER CAR SHOP MANUAL PAGE 333 SECTION 5
