They are wired incorrectly in that the smaller gauge wires to power the relay coil are in the socket positions where the larger gauge wire for the relay switch contacts should be and vice versa. So you have to remove the wire contacts from the sockets and move them around to the correct positions. When doing this. I also discovered that the crimps are weak and some pulled out. I wound up soldering all the terminal lugs manually. Then when inserting the relays, some are so tight that they push back out of the sockets. So you can make these work, but be prepared to solder, rearrange, and manually insert the terminal lugs in these cheapo sockets.

But note that the wiring layout is as follows:
85 - RED
86 - YELLOW
87 - BLUE
87a - WHITE
30 - BLACK

When installing as-is, RED goes to GROUND, YELLOW wire goes to your switch, BLACK goes to Battery (w/fuse, of course), BLUE to your accessory, WHITE is if you have something that is dual-mode but typically left unused.

To wire appropriately and minimize confusion later in life, the RED and BLACK wires really should be swapped in the relay connector housing so 85 is BLACK and 30 is RED. BLACK would then be to GROUND and RED would be POWER IN from Battery..as is standard for electrical wiring.

Easy enough to change, but they should have been set up properly to start with.
