Visible connector and circuit identifiers include P110/W103, P136, P137, EGT1/J158, EGT2/J159 and EGT3/J160. These identifiers indicate a Cirrus firewall-forward engine-monitoring and MCU harness. The exact Cirrus assembly part number and aircraft serial-number effectivity have not been confirmed.
Most of the markings shown are connector and circuit reference numbers, not the complete Cirrus assembly part number.

The Cirrus wiring manual specifically identifies J158/J159/J160 as the EGT 1, EGT 2 and EGT 3 connections to the firewall-forward engine harness. It also identifies P110 as the 28-contact engine-monitoring connection between the cabin harness and the firewall-forward copilot harness.
Cirrus maintenance information shows that the connector group P135, P136, P137 and P138 is used with the MCU 19900-001 configuration. Therefore, if the other two circular connectors in your harness are marked P135 and P138, that would strongly indicate a firewall-forward harness made for an aircraft equipped with the MCU 19900-001.
Cirrus SR22/SR22T Firewall-Forward Engine Monitoring and MCU Wiring Harness Assembly—Possible MCU 19900-001 Application
It appears to include connections for:
EGT and possibly CHT engine sensors
Engine-monitoring circuits
Master Control Unit connections
Alternator, starter or power-distribution circuits
Firewall-to-cabin engine-monitoring interface
Some of the visible circuit identifiers include EGT1/J158, EGT3/J160, P110/W103, P136 and P137. One portion closely resembles Cirrus forward engine-monitoring harness P/N 15035-001, but the exact assembly part numbers have not been independently confirmed. These identifiers indicate a Cirrus firewall-forward engine-monitoring and MCU harness.Important Buyer InformationThe exact aircraft year, serial-number range, configuration, and compatibility are unknown. Cirrus aircraft wiring harnesses may vary according to model year, avionics package, engine configuration, alternator system, and factory modifications.The buyer is responsible for confirming the identity, part number, application, condition, and compatibility before purchasing. Please compare the visible labels, connectors, wire routing, and photographs with your aircraft documentation or existing harness.This item is sold strictly as-is, as pictured, for inspection, parts, repair, or possible refurbishment. Any determination regarding installation or airworthiness must be made by an appropriately qualified aviation professional.
