I am hoping I can get some help.
I am trying to install turn signals and luck lights on my 1948 Chevrolet empanel hand truck, The flex signal substitution I have is lone three wires. Can person help me with trying to figure out my wiring conventional ?

I have 1157 tail lights and with 2 wires. I cant seem to figure out how to incorporate the turn signals and hazards.
I besides purchase a 5-pin relay but dont know where that would be placed in the schematic

Any direction would help .

The limitation is that you want the brake light filament to also serve as the turn signal filament. Remember that the other filament has to serve as the taillight. You want the brake lights to come on whenever you press the brake whether or not you are using the turn signals. But you want the turn signal to interrupt the power to one of the brake lights when you use that direction’s turn signal while braking.

Your turn signal switch will only send power to either the right or left turn signal when you move the switch to signal right or left. So you cannot wire the switch upstream or downstream of the brake light switch because it will stop the power flow to the brake light filament. If you wire it in parallel it will not flash the turn signal when you are using the brakes.

Your situation is even more complicated because you do not have a separate wire for the front and rear turn signals.

This is the reason they created 7 wire turn signal controllers. Those have an internal set of contacts that coordinate the turn signal/brake light function. I strongly suggest you save a lot of time and frustration and get one. It will be the best $30 you spend. Remember that the flasher has to match the voltage of the vehicle. Because you are using an 1157 bulb I assume you are converting to 12 volts.

7 Wire Turn Signal Switch The wiring actually gets catchy with a 3 wire control. I ‘m not even certain it can be done without at least adding some diodes to the wire. The relay might help but I am not sure how that would factor into the system.The restriction is that you want the brake light filament to besides serve as the sour signal fibril. Remember that the other filament has to serve as the taillight. You want the brake lights to come on whenever you press the brake whether or not you are using the turn signals. But you want the turn signal to interrupt the power to one of the brake lights when you use that direction ‘s turn signal while braking.Your turn signal switch will only send power to either the proper or left turn sign when you move the switch to signal right or left. So you can not wire the interchange upriver or downstream of the brake faint switch because it will stop the power flow to the brake alight filament. If you wire it in twin it will not flash the act signal when you are using the brakes.Your situation is even more complicated because you do not have a separate wire for the front and rise bend signals.This is the reason they created 7 wire turn signal controllers. Those have an internal set of contacts that coordinate the turn signal/brake light function. I strongly suggest you save a lot of prison term and frustration and get one.

hoary 37 Master nailed it. A 3 telegram switch does not share the brakelights. You need divide bulbs with that 3-wire switch.

Diodes habit get the job done. It is an interest technical problem if you think about it. One light needs to keep flash when you step on the brake. There needs to be some active throw.

They do make small black boxes to connect asian cars with distinguish signals to trailers. Trailers typically combine the signals with the brake lights. One of those boxes might work, although in my feel the dependability is atrocious. They besides dim the bulb a little.

4-ways add another level of complication.

https://www.amazon.com/CURT-58240-N…rter+58240&qid=1572387922&sr=8-5 Thank you for your remark. It has been driving me brainsick because I was trying to figure out how I could get it all to serve. For what its worth I cam gon na see if I can use one of the CURT 58240 Non-Powered 3-to-2-Wire Splice-in Tail Converter. See what happens I will post my results this weekend. Again thanks for the help .

I understand your think and agree that it might work. I have used a converter like that to connect preview lights to a car that had autonomous turn and brake lights. That little bootleg box is truly a plant of diodes ( as I noted in my earlier response ).

My suggestion is that you need initially wire the car as though it has independent turn and brake lights. The front go signals have to be in the circuit after the turn sign switch and wired in analogue with the converter. then add the brake cable to the converter and connect to the double filament light bulb in the taillights. Basically you are making the car taillights function like trailer taillights lights.

here are 2 things to consider.
– Do not try this with LED medulla oblongata until you can get it to work with regular fibril bulb ( which I think you plan to use ). There are lots of instances when the first gear current draw of LED bulb is not sufficient to make electronic devices work.
– The device might not work if there are no bulb on what is labeled the “ car ” side of the converter. While it is a promoted as a “ non-powered ” device that just means it does not need a branch baron feed into it. It still requires world power to work. The might comes from the call on signal and brake light functions. If there is no load upriver of the device it might not work.

Let us know what happens .
