I have one wire I have not been able to find a home for.  This is a grey
wire with a male spade end which comes out of the bundle of wires (largish
red, red and black, etc.) which go primarily to the coil.

The bundle comes out of the black plastic box mounted on the port side of
the firewall.  After the black box, the grey wire seems to come from the
front of the van somewhere.

I've looked at the schematics in Bentley, and most of the grey wires seem to
be in the front of the van for speakers and such.

Thank you for any info,

Karl Wolz
