Q: LSU 4.9 vs 4.2 z.p57851 2 years agoAnswer
I have an AEM UEGO wideband controller currently hooked up to the OEM Rear O2 sensor (prior install, not my work), and am looking to replace it with their Wideband O2 sensor. Is there any difference in the harness specifically between the LSU 4.2 vs the 4.9? Does it matter (apart from the 4.9's better life expectancy) which one I get for my existing UEGO Controller? Thanks!
A: The connectors for the 4.2 and 4.9 sensors are different, and they are not interchangeable.
