          Extended O2 Harness

          Harness worked perfect on my 86 Saleen with long tube headers. Plenty of extra wire so I could route it to prevent damage.

          Perfect for longtubes

          Perfect upgrade to go with longtubes. No additional connectors or splices to get in the way and cause additional circuit resistance so a good clean read is provided. Perfect fit for a good clean install
