91 Shorty- loaded; Have one more loose connector hanging behind the dash left of the steering column. (wondering if they just had one dash harness that had all the option connections regardless if any certain option was ordered or not....) Anyway the connector in question is a four conductor plug with four wires attached; colors are; green; blue; gray; red (or a dark pink) with a black stripe. The other end of the wires go into one of the taped harness and seems to go out into the front engine bay but could not trace it without unwrapping the large harness...don't want to get into that. Looked all through the Electrical Manual and could not find any illustrations for any 4 wire connector with those colors. Maybe someone out there knows.
Thanks
