Found a few broken wires, I have the diagram but can't seem to find these wires

B18c (p72 Gsr) with p72 ecu (hondata s300)

try that
or search for pinout image

 

I have that diagram already, but the colors don't match

 

Looks like someone did some tinkering..


If it were me, Id get a whole new harness. Old wires get corroded, copper oxidizes, etc..

These cars are 20 years old. Wires doesnt last forever and since someone decided to splice, might be time for a replacement harness


I know a guy who selld complete harnesses, PM if interested Alot cheaper than RYwire

 

Yeah more than likely that isn't factory.

 

Ive checked a few wires to this diagram and it's right. You'll just have to look at it "upside down" according to your pics above

Looks like someone was adding wires possibly for VTEC solenoid, pressure switch and knock sensor?
