I am trying to weed out my whole harness from a 91' JDM integra W/B16A1 in order to simplify it. I am only needing vital Engine functions/ guage cluster wiring to remain. I have used pinouts and tracked most downm, but what are these red boxes (2 of them) with caps on them that many wires run to? Do I need them because some ECU wires run there. Also what is the PA sensor, is it an actual seperate sensor in the engine bay?

Thanks in advance,

Chris

 

BUMP... Does anybody recognize what I am talking about? These Red boxes (clearish red boxes with a dozen or so wires of the same color comming from them) are holding me back. Another question; what is the sensor called that is on the Cat Converter? I dont have the motor in front of me and it is hard to trace these wires. I have had the motor since 2000 and just now gettting into my project, a VTEC Mini.

Thanks again,

Chris
