Don’t know if this is the right place, but I need some help installing two Insteon switches that control two lights, first gang box has red, white, black and ground, second gang box has red, white, black and ground, here’s where it confuses me, all three way connections always confuse me, so in the first gang box in the ceiling that one light is connected to has three black wires, three white wires and one red, other gang box in ceiling has three black wires, three white wires and one red, I can get the switches to work any help would be appreciated, i think sometime ago I had to switch the wires in the gang boxes or something like that.

Nice picture. Is this a ceiling box? You want to install a switch into a ceiling box? Will the switch be wired to any fixture? What was here before you opened it? Do you have an idea where any of those wires go on the other end?

Is their a manual switch controlling the load at a different location? The white and black connected together. Looks like a switch loop and the white in that case is not neutral but is a line or switched load from the remote switch. Technically it the whites should have a piece of black tape around it or have a black mark around it to verify it is not a neutral but has power on it.

I cannot see from the pictures (sprayed texture and other obstructions in boxes makes it difficult for me to identify source of the various conductors).

For me to even attempt to help, I would need to identify total number of "cables" (cables will have either two conductors, black and white, or three conductors, black, white, and red. Ignore bare copper conductors.) coming into each box and to what each conductor is connected.

Does each switch control one fixture? You mentioned "three way". Are there other switches that control these fixtures not shown in any picture?

Yes, it’s basically two switches controlling two lights, it’s a hallway, so one switch it at the beginning of the hallway and the other is at the end of the hallway,the two lights are at each end of the hallway. Thanks

This is how the wiring looks

Both switches get replaced by an Insteon switch. One then controls the light itself. The other one just controls the switch with the load and has its red load wire capped off. Both get cross linked. The travelers between the switches are reused to power and neutral between them. As needed.

No, Uberkc, why would anyone put a switch in a ceiling!!!??!!!. It’s for reference as to how the wires are connected together in the junction box in the ceiling, hence why the Insteon switche not working,?!!

Hi Brian H, thanks for your help, that’s what I did , I replaced both switches, but in box 1 has power, ( black, white. Red, ground) box 2 only has white red and black, that’s why I posted the pictures of the two ceiling boxes (light boxes) but in those boxes it’s got red connected to black and the other box has red connected to white, so the switches are not working.that’s what I need help figuring out.

You showed a picture with a single box having two Insteon (and an additional third) switch, which does not match the illustration. And the wires in the pictures of the ceiling boxes don't match the diagram.

Still, I can tell you how to modify the wiring in the illustration. Whether or not this matches your installation, I will leave to you to decide. I am not sure that it does. In theory, each Insteon switch requires a constant line input and neutral. One Insteon switch will directly control the load (the two light fixtures in this case.). The other Insteon switch will not be connected to any load. The two Insteon switches will be put into a scene, with both as controllers.

Left switch box: connect lower black conductor to upper black conductor and to Insteon black wire. Connect lower white conductor to upper white conductor and to Insteon white switch. Connect Insteon red wire to upper red conductor.

Upper left ceiling box: connect all white conductors together, and to fixture screw (this would be the neutral). Connect upper-left black conductor to upper-right black conductor. Connect upper-left red conductor to lower-right black conductor, and to other screw on light fixture.

Upper right ceiling box: connect lower left black to one fixture screw. Connect all whites together, and to other fixture screw. Connect upper left black conductor to upper right black conductor. Put a wire nut on upper left red conductor, not connected to anything else.

In lower right switch box, connect black conductor to black wire on Insteon switch. Connect white conductor to white wire on Insteon switch. Put a wire nut on the red conductor not connected to anything else. Put a wire nut on Insteon switch red wire.

Tie all bare copper conductors together, in all boxes, and to Insteon switch bare wire.

Cross link the two Insteon switches, making each a controller of the other.

Good luck.

Thanks Oberkc, that sounds like it, I will give it a try this weekend. The box I showed does have three insteon switches (3 gang box) the one to the far left is what’s going to be connected to the hallway lights.
