Good afternoon,
I've had my S2000 for a few months and have been recently looking over the wiring to make sure everything looks ok. Under the hood on the passengers side I have a few wiring looms that look to be deteriorated. Overall the wires themselves look good and I am planning to re-wrap them in new wire covers. I have one wire where the insulation has come off and there is bare wire sticking out. The wire is still connected but just barely.

I have attached a picture. It is one of many wires connected through a large bunch of wires and is connected to a plastic "blob". Would anyone have any suggestions as to how to fix this? Would wrapping it in electrical tape suffice? What is this "blob"?

Thank you in advance for your help.

Take the rubber thing of the blob I think you will find an unused connector inside.
It's just a rpm signal for diagnostics.

 

Thank you for your reply. I will take a look. Is this pretty common to have wire looms deteriorate over time? All of the other wire looms/connectors look to be in good shape, its only the wraps in this section that look cracked. I plan on wrapping these to prevent any damage.

Thank you

 

I have a small section of wiring loom like that - figured it was a rodent from the prior owner, but it's still a bit of a mystery to me. I left it alone as it's a small section on the drivers side, and the wires themselves appear to be fine.

 

I would say someone shaved the insulation off the wire for some reason, it is an rpm signal wire for idle rpms testing. Just tape it up and you'll be fine.
