Description
Product Overview
The PSI EXT-4L80-13 is a plug-and-play adapter harness built for a 4L60E to 4L80E conversion kit application. It connects a factory 13-pin 4L60E harness (1997-2005) directly to a 4L80E transmission, so the 4L60E to 4L80E transmission swap goes in without cutting or splicing any factory wiring.
This Gearstar’s 4L60E to 4L80E adapter harness requires custom tuning to operate correctly. The tan wire connects to pin 22 in the C2 red connector, and the orange wire connects to pin 23 in the C2 red connector.
