That part number is listed for many other cars for various purposes, but not for the Yaris. The Yaris fog light relay part number is 90987-02027.

I am not sure what the difference is between the two, but I would check both with an ohm meter to see how they compare.

Looking at the bottom of the relay the terminals are arranged like this:
1 2
| |

5-
3-

On the correct fog light relay:
1 to 2 is the coil and should read somewhere around 100ohms
3 to 5 are the contacts and should be open

1 to 3 and 1 to 5 should be open
2 to 3 and 2 to 5 should also be open

I bought this relay a loooong time ago when the other thread was still around (with the DIY fog lights OEM style).

Was the relay the issue? If so, I will order the correct PN. For reference, I have the Denso relay 90987-02012.

I have tried 3-5 different relays, so I'm pretty sure it isn't a relay issue. Still trying to get to the bottom of it.
