Default Custom KLX250 Build: Help with Ignition

As the title says.... I have a custom KLX250S build going on, but i'm stuck on the ignition.

Short Version: Is there a small key'd ignition that works on a 14 KLX250S that anyone knows of?

Expanded: I am trying to replace the stock key'd ignition on my custom KLX250S. The stock ignition has the fork lock on it and I don't need that anymore and want to go with a smaller, mini ignition that just has the key part. The stock ignition has 4 wires. I bought a small key'd ignition that also had 4 wires to replace it with. Wired it up, bike doesn't want to start. Accessory/headlamp turns on, but no ignition when i press the start button. Swapped the stock one in and bike fires up. Bought another small key'd ignition with 4 wires that said it would work on a kawi. Same thing happened as the first one.

Did some more digging. Tested all of the ignitions with my multimeter and it seems like the logic for the stock one is different than the mini versions.... I apologize for my lack of electrical engineering knowledge as you can see in the way i described how its behaving below.

Stock:
In the OFF position: The two "off" wires are live, the two "on" wires are not live.
In the ON position: the two "off wires ARE LIVE, the two "on" wires are also live.

Aftermarket/Mini:
The difference is when in the ON position, the "off" wires are not live. Unlike the stock KLX ignition when its in the ON position, both the "off" and "on" wires are live.

Does anyone have or know of any mini key'd ignition that works with a 4 wire Kawi street bike with 4 wires? OR if anything like the Mgadget RFID wireless ignition would be something to look into? I like the idea of just having a small key in a hidden location over the RFID key.

Thanks so much in advance. I have been putting off finishing this bike because I cant figure out this ignition part. Its the last thing i have to do with it (Seat is getting leather right now)

Pics below!
