How do I plug esc fan if there's no aux output on the ESC?

[shingo]

I just bought a AXE 550 3300KV kit and it come with a fan but I can't attach it to anything.

Where should I plug it? Do I put a Y cable on the RX cable?

It's my first ESC without an aux port.

Thank you

Simply plug it into any unused channel on the receiver. If you don't have any unused channels, here's another solution (I'm assuming that the ESC fan lead has only two wires (+ & -), with no signal (typically white, or yellow) wire):

Purchase a Y-cable, plug it into Ch. 2 on the receiver, then plug the ESC into one of the 'Y' ports, and the ESC fan into the other 'Y' port. The reason I'm suggesting plugging the Y-cable into the Ch. 2 port (instead of Ch. 1...again, assuming the other two channels are occupied) is because of the length of the cable, and positioning of the ESC & ESC fan (ie. one is, obviously, on top of the other). Essentially, in addition to providing power to the ESC fan, the Y-cable also acts as an extension, allowing the receiver to be placed further from the ESC & ESC fan (ie. placed closer to the servo, which can be quite helpful, due to some servos having fairly/very short wires).
