Ok, i've figured out how to fix the semi auto problem. Its very simple, trust me.
All you have to do is take the wiring connector, and if you look VERY closely, you will see a very small ridge on it. This is what messes up the selector switch. All you have to do is take a piece of sanding paper, and sand down the ridge on the connector switch, and make it smooth. Then your semi will work fine.
That being said, this is good but I'd still go with the ICS or TM wiring.

Ok i'll just make myself clear right now, this stuff sucks.
I'm personally not crazy about guarder parts, i've bought tons of them and personally, only the piston, the hop up buckling (which isn't the best) and the selector switch are the only ones currently in my gun. But DEFINATELY DO NOT GET THIS.
The reason i'm saying this is because, YOUR SEMI AUTO WILL NOT WORK. Maybe if you modified it a little bit you could get it to work, but i've worked on this for hours and couldn't get the semi to work. Get the CA wiring with an ICS wire connector (if you can find one, I think they have them on here). The CA wiring is good, but the wiring connector isn't that great, hey but at least on the CA one the semi works.
