Replacement Torch not working Two trigger wire to single trigger wire Flux welder

[Jrawls]

I am stumped I ordered a replacement torch like the one above and it has a single trigger wire. The new torch has two trigger wires. Now the wire feeder is not running.
I tested the board capacitor, resistors and fuse is fine.
I tested all wires for connectivity all is well as the wire motor. It is fine. For some reason no power is getting to the wire feed when I press the trigger. I tried wiring both trigger wires together and separate (blue and brown) no action the fan works on the welder and the high/low current switch works. I think it has to do with the trigger wires

One side of old SW went to circuit ground other to board try grounding I wire and other to original connection.

I think you'll find that one wire (either one) should just connect to the same place the original one wire from the old torch connected to. This will disappear down into the machine. The other wire should normaly connect to the main welding power lead. On some machines this is done where the power wire (the large sized one) connects to the feed unit nozzle at the feed unit itself. This main welding power wire also disappears into the machine and will be connected by a bolted connection somewhere inside. If it would be easier you can connect here instead but it's usually easier to loosen the bolted connection on the wire drive unit and slide a large crimp on terminal under this connector (or even just poke the switch wire under the nut and washer and clamp it there so it is making contact with that large power wire.

Thanks guys. I figured it out. You were correct.I wound up connecting my old trigger wire conetion and I made a connection to the torched main wire and my wire feeder and torch came to life. I got to thinking the circuit is not complete. So I completed it
