Does anybody have a photo of the actual wiring placement for a stock (1980 Cutlass Supreme) Non- AC heater blower fan? I have mine connected and working but I have no grounding tab to connect to, just a jumper wire to ground at the moment. It's been apart so long I have no idea how the wiring was laid out originally, or where the ground wire is to be connected. Looked through all the bags of pieces and parts and can't find anything that resembles a grounding tab for one wire. Any help is appreciated.

There is a brass 90 degree terminal that screws into the blower motor with a fine thread #8 sheet metal screw.

Pretty sure it screws into that hole.

The factory screw is a 8X18 fine thread screw, difficult to find coarse thread should do and is a lot easier to find.

If you really need/want the correct type tab and bolt there out to be one on some of the spare used blower motors I've got lying around.

Let me know.

-Thanks for the photos, ELCAM.

-I had a feeling that grounding tab was what I was searching for. I figure I’ll make something up and make it work. Not too concerned about being perfectly correct with this car, as long as it looks presentable. Appreciate the offer though, ck80.

No worries, you change your mind let me know. A little cardboard and a stamp is no hassle to me.
