Has anyone seen/got a late Bay wiring diagram that includes the circuit track for fog lights? I've checked the ones on The Samba and Vintage Bus, but neither show the fog lights - presumably, Americans didn't want them ) Does the Haynes manual show them? I've seen the hand-drawn one with a new wire from the battery through a whopping 20a fuse, but that one didn't appear to be tied into the lighting circuit - and as the 1978 owner's handbook (at least) shows the fog lights on fuse 7, there must be a proper diagram somewhere, mustn't there? Funny, isn't it, I've always preferred the old-fashioned diagrams with images that look like the item (i.e., a headlight that looks like a headlight) rather than the more electrickery version that just shows a switch with a key to look at in the index.
What Paul said but take it from the circuit that has just the one rear light fused and not the rest of the circuit. VW had a wonderful safety idea of having the rear lights run on 2 circuits. Genius really.
Both, rear and front ones. L20 rear one with Black/Purple all the way back and front L22/L23 starts with Black/Purple and ends with Yellow 2.5. Have you seen this one Nigel under your original post? http://www.thesamba.com/vw/forum/viewtopic.php?t=186468&start=40 I am still waiting from some members in here, that have an original unit installed, to confirm the colors.
