What are the tabs for on the GMPP Fuse box?
 

I'm looking for for a relay and socket that clips onto the GMPP Fuse box tabs in the picture.

Does anyone know what the tabs were used for originally?

Thanks,
Stan

Are you trying to add a relay for another fan or are you talking about the metal tab on the outside?

I am looking to add at least 2 relays one for AC Compressor and the other for a brake vacuum pump. I may add more in the future. I used the extra relay slot in the box to convert from a 1 or 2 fan setup to a series parallel High / Low setup.

Just stole the pic with the metal clip as it showed the black plastic tabs molded on the fuse box.

I could add one of many nice looking relay boxes available, but thought it would me more OEM like if they were on the fuse box.

Thanks for the reply.
