Yes.

First, get the instructions: http://www.hamgadgets.com/index.php?route=product/download/download&download_id=76

Second, go to the section entitled Adding GPS Timing.  It's on page 35.

I understand that part, but my problem is that I don't know what GPS receiver I need I can't seem to find one online.

Amazing. 
I would have researched that question, had you actually asked that question instead of “is there any way to add a GPS time source to the id o matic iv repeater controller?”

[WRVY769]

yes, I couldn't find anything on it.

Just look for serial output GPS clocks. They’re pretty interchangeable. The NMEA data string has been standardized. 
For example here’s an NTP server that should work:

Here’s another: https://www.worldtimesolutions.com/products/gps_time_server.html

We used to buy high end hardened ones made by Schweitzer Electric Company, but they were more expensive.

Be sure you look at a GPS clock that has a TTL output. The second one I posted doesn’t. Of course that could be fixed with a level shifter, but there are TTL units out there. 
Sparkfun has an inexpensive unit that might work. 
Google “TTL NMEA output GPS clock”

Tons of GPS boards on ebay that support ttl output. But why ? What are you trying to accomplish with GPS ?
