[91 Corvette]

Can someone post the adjuster wiring diagram pls (motor to switch)? I bought a pair of Coupe headlights to put on my Corvette...

This is all I could find.

101 = Headlight control unit. (located below the steering wheel on the Coupe).

Is item #3 a ground wire? Is the GR wire from 101 , + 12V? Do you have a part number for the headlight control unit?

 

[Davren]

Yes.... item 3 is a ground connection to the vehicle body. Most wires labelled with N (Nero = black) are ground wires.

Yes.... the GR (Giallo/Rosso) wire provides a +12 volt supply from fuse 5 in fuse/relay box 96, to rheostat 101 and the headlamp adjustment motors.

This old eBay listing: https://www.ebay.co.uk/itm/Genuine-...ment-Dashboard-Switch-735268798-/274106972575 shows it as part number 735268798. The Fiat parts catalogue shows 735268798 and 720953080 but both are no longer available from Fiat. I don't know what difference there is with the 2 part numbers. It could be one is brown and the other black plastic.

One here for €90 (EUR) https://www.scricambiusati.com/prod...santiera-comando-regolazione-luci-fiat-coupe/
