For $15 you can gain access to toyotas TIS site for 48 hours and download what you need.
Although I am not familiar with this car and that fuse if the fuse is feeding a relay, said relay or harness to relay likely has a short in it. You need an ohm meter to test suspect parts.
In general momemtary relays that carry high current will have low input resistance but likely have an impedance of 5 ohms or more and should not measure as a short (zero ohms).
Relays that are lower current and on all the time might 100 to 1000 ohms depending on the application.

This should get you going.
The starter relay would be the first thing to check as thats the only component to load the 5amp current path. If it checks out, then it would be a wire shorting to ground somewhere or even the park/nuetral sw.
If you unplug the starter relay, and then put a 5A fuse in and it doesn't blow then the problem is most likely the relay.
