i doubt you will have an appropriate cable for EQMOD in your "stash"
The mount requires TTL signals through a DB9 serial port type connector at the scope end. So you need to convert RS232 into TTL, and if you don't have an RS232 port on your laptop you'll also need a USB-serial adapter.
I found it easier to just buy the cable from Bintel rather than try to cobble together my own. Once you've installed the driver for the USB-serial chip embedded in the cable you're away.

I now use EQMOD exclusively, and never use the Synscan hand controller. EQMOD gives you the flexibility and convenience of software polar alignment (i use alignmaster), PEC and, importantly, dithering in conjunction with PHD and BackyardEOS (APT may also have a dither feature). Not to mention that you can sync to any object you like with a mere keystroke in Stellarium. EQMOD will also provide guiding corrections from PHD, so no need to run an ST4 cable from the guider to the mount.
