Im looking for a labeled overhead view of the 4.2 I6. while tracing a ground today, I found some hoses that were loose and I want to know what the part is so that I can research it in the Haynes. No diagrams in the haynes either to help out. Its about a 1/4 '' tubing attached to a harness type thing on the upper passenger side towards the firewall side of the engine. anybody got a clue as to what this is?
