The wire bundle going to the back of the truck fell off of the hanger and landed on the exhaust (sometime ago). I was in the mountains at the time and managed to wrap everything up and seemed like everything still worked, so I scheduled the repair for a later time. Three or so years later, I'm replacing the exhaust (down pipe back) and figured this is the time to cut/splice the burned sections and make it nice again. Everything was fine until I cut out the damaged O2 sensor wire.. I didn't know that the O2 sensor wire is shielded, if only I had got curious about the dashed lines on the schematic. Been a while since I read one - my only excuse.
I can't tell if the shields are grounded but they do appear on the schematic that they are connected together at the junction box(?). If they aren't grounded, what would be the point? Where I am making the splices, it's just before the O2 sensor connectors. So I think my question is:
Can I just splice the signal wire and ignore the shield or do I (somehow) have to splice the complete coax wire. Something I don't recall ever doing.
Sure hope somebody can give me some advice, as my truck is basic transportation and I need to get going.
thanks! jim
