Unknown wire harness
 

Hey guys. A buddy of mine just picked up a 2005 WRX that had a CEL of P0031 heated O2 low voltage bank 1. He replaced the bank 1 O2 sensor and still has the CEL. We found this bad boy tucked away. Can anyone identify what it is to? The EGT sensor on the up pipe is plugged in to its harness and we cannot see where there would be another plug for this harness. If someone can look at there's and get back to us it would be greatly appreciated.
