The 510 Realm

can anyone provide me with more pictures or a diagram for this delay unit ?
below is a pic of the Y harness in question. I cant figure out all the pin outs with this picture

Is that even an actual Datsun part? I've not seen the like before (or, more precisely, heard about it).

I've seen this part lurking in many jdm interior pics. Craig in Tokyo listed it as a Datsun sss coupe part. could be like the air con..... dealer option?

The all original Coupe I saw at Canby a few years ago - the grey one now in Carters hands, had this switch. I clearly remember looking at it as it was the first time I could physically inspect one. I do believe they were factory on the higher end Coupes only.

bump for knowledge

maybe a circus peanut has such a switch and wire info can be gleamed ?
