I have a 3-pin connector and 2-pin control board port. Says it's compatible with 3018, should I modify the connector?

I don't know, the 3018 pro I purchased ran for only about 10 hours and only and lost power, checked power input and out put, 0 volts DC, Sainsmart sent new power supply. Hooked up and same thing happened, noticed spark when inserting power, still trying to get answer from Sainsmart.

How long is the cable?

the cable is 1 meter long for each switch

The current Genmitsu controller have only 2 wires for limit switches, is there cable adapters?

Sounds like you have the Pro vs the Prover. I don't think the pro controller box can handle the Z limit switch. I purchased the Prover controller to replace the original controller to do this.

Are there any directions included with these switches? Mounting hardware?

No instructions included, and they came with only that which is pictured. Youtube has many tutorials on installation and 8f you need mounting hardware, you can find these free on thingiverse as STL files to print out, or as in my case, adapt and print for our 3018 CNC. Good luck!
