Socket

I've bought them from fleabay in the past. They are called Powerlet plugs/connectors.

 

I may have one of those I chose not to use, yours for postage, let me check tomorrow and I'll get back to you @Malcolm Woods .

Small type is the lhs one.

 

@Malcolm Woods As said I'll check garage tomorrow if I'm correct got one for my T bird but just used the holder and swapped it out to take vehicle cigarette lighter type socket to fit my air bed etc.

 

Apologies @Malcolm Woods turned garage upside down unfortunately I can't locate Triumph acc socket,
Sorry for possibly raising hopes.

This is where I got one for my T-Bird 1600. Oddly the socket on its own was listed at £35 but I got the kit, which includes the bracket and bolts as well as the socket for just £23. You can get the sub-loom to plug it straight into the original wiring loom too for about a tenner.
