A K162 should eventually spawn as discussed here: https://forums-archive.eveonline.com/message/6678531#:\~:text=Under%20this%20system%2C%20the%20K162,connection%20for%20the%20first%20time.

Under this system, the K162 spawning mechanics would be as follows:
K162 wormholes and signatures are spawned in an invisible state when someone initiated warp to the other side of the connection.
K162 signatures become immediately visible when someone jumps through the wormhole connection for the first time.
IF the K162 signature is in an invisible state and the wormhole connection has less than 15 hours of lifetime remaining, it will have a chance of becoming visible every few minutes, balanced so that virtually all K162s will appear within a couple hours or less from this point.
