Got a new harness from M&H and it fit perfect. They had to use my fuse block with all new connectors, instrument connector and cigar lighter fuse holder so I sent my original harness in too. It was not part of their existing catalog but they had the GM blueprint and they made it to that. Nice new flexible wire and bright connectors, all stock. My harness was trashed by a hack and hew specialist, looked like vermicelli exploded behind the dash!
