13 pin connections
 

Hi,

Just bought 2005 XC70 which has 13 pin towing light socket. Fine I need an adaptor, but the socket is damaged. So I buy a replacement socket, only to fine I have to cut the wires as the back of the Volvo socket is sealed. The wiring diagram with the socket tells me which colours to connect to each pin, but the wires are all white and just labled NR1 to NR13. So I guess it's logical to connect 1 to 1, 2 to 2, etc. etc. However this does not work!

Does anyone know what the correct connections should be?

Cheers

Cheers,

I'll give that a go, but it does seam illogical for Volvo to label wires 1 to 13, if you're not supposed to connect them to the corresponding 1 to 13 pin numbers!

Hope not telling granny how to suck eggs, but the plus should be marked 1 to 13 so if you use this it should work. Be careful using wiring connections as norammly it shows the back of the plug (where the wires go) and not the plug pins.
