as the pic says.. what is that? and why is it duct-taped?

Was it factory duct-taped?

EDIT: i meant electrical taped lol

 

Yes, it comes from the factory like that. I believe it's all wires (including the ones that go to your ignition coils, amongst others). Haven't looked at it in a while.

 

its the main wire harness - bunch of wires binded up in electrical tape running from the ecu to all electrical components of the engine (coils, injectors, etc)

i went around my whole engine bay and retaped over my wires with new electrical tape last year, looks good as new. or you can also get some wire loom

 

Cut it off... you don't need it...

 

don't listen to him... i think hes' tryin to trick u!!!
