A/C Idle-Up Recognition Wiring - Gen 3 LS Swap Add-On

Adds the A/C idle-up recognition circuit to your Gen 3 LS/Vortec standalone harness, allowing the PCM to recognize when the A/C compressor engages and bump idle speed up to compensate for the extra load — keeping idle smooth with the compressor cycling.

Designed to pair with our 99-07 Gen 3 LS/Vortec Engine Controller Kit (KIT-GEN3-DBC-AUTO) — note in your order comments if you'd like this added.
