Custom Adapter

[SpeedyBooty]

So I’m making this custom light bar for my axial deadbolt and I was wondering what this connector is called? I'm making an adapter so I can hook it up to a battery and run it so I don’t have to take the body off and undo the wires in the receiver box, since it has 4 wires can it be soldered onto a 3 wire servo type wire? Thanks

There is a reason for the 4 wires and putting it on 3 wire plug probably won't work. Companies don't spend extra money when they don't need to. That connector is also keyed, meaning it only assembles one way and prevents you from connecting it backwards. If you find another connector you might want to make sure you have a way to get the correct orientation.

You can look on Amazon (Mouser, Digikey or Newark also) for 4 pin connector. I found this one right way. It has 4 wires and is keyed. Probably looks familiar? It's a 3S balance lead.

Ok so what if I took the wire and put it on a switch to control the lights would that work better

Like a physical switch? You could but you would have another switch on the rig. If you know what pins are power and ground you might be able to add them to an aux channel with an adapter. Something like this. But you still have the 2 other wires that are probably control wires.

What is the light bar, do you have link?

It’s more of me just putting led lights into the already available light bar on the axial scx10.2 deadbolt, I want the lights to be completely spectate from the rig, having it’s own battery will be very easy for me to take the body on and off instead of taking the wire out of the receiver box everytime

Got it.
I'm not sure why there are 4 wires? What does that connect to?

I'm making some guesses about your setup here so it could be completely off?

A single color LED has an anode (+) and cathode (-).

With multi-color LEDs can have several anodes or cathodes, depending on what you have. A 3 color LED will have 4 wires. I'm guessing this is what you have a 3 color LED setup and there is a controller somewhere?

This shows raw LEDs and do not show current limiting resistor as well. That is required so you don't "let the smoke out". If you have an LED kit it probably has the resistors in the package.

With the multi-color setup, you may not need all the wires if you have the color you want from one of the LEDs. If you don't have the right color, then the colors need to be mixed. It gets more complex and there is probably a controller to do that.

If this is your setup, you would need to switch the common wire.

If you have a single color LED setup, they only have power and ground, like the first picture. No power = no lights and you could just the servo connectors and use a simple switch.

Or if you want to be a bit fancier you can use magnet mounts to make the connection for you.

4 wire LEDs are RBG LEDs that are designed to be used with a control unit of some type. If you have a controller for them, it should have a two wire battery hook up. If you don't want to use a controller, then I'd recommend going with single color LEDs.

As to the question about what the connectors are called, I'm not sure about the first one. It's not a standard RC connector that I'm aware of (plus the pics a bit blurry). The second one is a futaba connector.

JST-SM connector.

Yup 4pin JST-SM connector specifically.
