Recently, I rewired my 1968 Beetle. Everything is working good except for when I put the ignition switch on the On position, the brake lights come on as if I've been pressing the brake pedal. When I press the brake pedal nothing happens.

I disconnected the cable from the master cylinder and the light still comes on when I put the ignition on On position. The only cable that I am doubting is the black cable that comes from the steering wheel....

but I used the schematic the Samba.com, and all the schematics from 1968 til 1969 all point to the same position on the fuse box. Can anyone give me an idea on what's going on? Thanks, Kg4qpb. Confused

check this page for additional schematics http://www.oldvolkshome.com/, helped me when doing mine.

but it sounds like you have a run of wires swamped for rear taillight bulbs.

top bulb should be brake lights only, middle bulb should be high element turn/flashers and low element are driving lights. Is everything else working that way?

check your fuse box. sounds like you have the brake lights hooked to the wrong fuse.

the black/red wire should be on the 1st fuse on the right hand side of the fuse box when you are looking at it from the trunk.

Had the same problem a while back, are your break switches three prong? I had a couple wires on the wrong leads, it will light the rear lights. Also if they are disconnected it will light the rear lights.
