The wire listings in the components catalog follow the British color coding system as in the original harnesses & wiring diagrams.
If the wire is listed with a single letter then the wire is a solid color without a stripe. Thus G refers to a solid Green wire.
A wire listed as GW refers to a green wire with a white stripe (tracer). WG refers to a White wire with a Green stripe.
The following letters are used for colors in the British system.
| B = Black | G = Green | LG = Light Green | K = pinK | N = browN | O = Orange |
| P = Purple | R = Red | S = Slate (gray) | U = blUe | W = White | Y = Yellow |
Two types of wire are listed in the components catalog, Braided " B " for early cars and PVC " P " for later cars. The braided wire we supply starts with PVC insulated wire which is then braided and lacquered to look like the original. Thus braided wire is more expensive than PVC. In addition, various sizes of wire are available depending on the number of amps the wire will carry. British wire sizes go up by the number of individual copper strands that make up the wire (i.e. 9, 14, 28, 44, 65, 84, 120 strands.) Not all colors are available in all sizes. The bullets for the wire ends also come in various sizes. The outside diameter of bullets is always the same so that they will fit into the standard sleeves commonly referred to as "snap" connectors. The diameter of the inside hole of the bullet varies according to wire size. Some bullets are "solder only" and some are "crimp or solder." Crimping requires a special tool which is listed in the catalog.
