Two empty sockets by the battery. Which one is the Accessory Supply socket? Please help identify.

it's the Black connector to the right of the photo. Black wire is Ground, Brown/Green wire is permanent live and White/Red is ignition switched live.

For the switched live, you'll need a standard relay in the centre position of the three relay sockets lined across the car in the Trunk Fuse Box and a 20A fuse in F11 of that fuse panel.

For the permanent live there's a 10A fuse in F17 in the Driver's side fuse panel.

 

Thank you so much astromorg for your detailed description.

Now I realize the Accessory Supply Socket is meant to be used in conjunction with part number C2A1403 Auxiliary Power Socket which comes with various socketed cable harnesses and what is essentially a cigarette lighter socket with spring-loaded cover. I understand C2A1403 is no longer available, so we have to do some wire cutting and splicing.

Just to make a small clarification on the wire colors:

1. B Black
2. NLG is Brown w/LightGeen
3. PN is Purple w/Brown

Cheers !

 

Sorry about the colours. Early X100s had the colour scheme you describe, but I inadvertently overlooked your 97MY. Apologies for that.

Standard insulated Lucar type connectors will plug onto each of the three terminals in the accessory socket.
