Hello everyone I'm new here and don't really know how to do everything yet so I'm sorry if this is wrong but here it is I have a 2001 Honda Civic Ex sedan D17a2 motor and BMXA transmission and I was wondering about a couple wires I found and was curious to now if they're normal.the Black wires

 

It is normal. Some wires are braided to shield the signal going to the ECM/PCM from interference from noise created by other systems such as an ignition system.

See example in circuit diagram:

 

Thank you for your help sir have a good day
