Rich,

Below is a message that Charlie Burke sent recently showing the color codes
Airstream used.  Note that if you matched the colors of the trailer wires to
the colors marked on a new trailer plug, you got it wrong, since the
standard has changed.   Decoding his message, if you hooked up blue to blue,
you've got the charge line hooked up to the brakes.

Your new tow vehicle plug should have a diagram indicating the color and
function for each pin, which should help.  Just remember that the trailer
side is a mirror image of the tow vehicle side.

I'd try checking your work against the color codes Charlie sent, and if that
doesn't clear it up, start testing each pin individually for correct
function and/or shorts.

Don

Keep in mind the plug is labelled on the back by color not function.
