VMP Performance VMP-SUP066 — 11-14 Coyote 5.0 L IAT Harness for PCM Tie-In (SC/Turbo)

This harness gives precision control over intake air temperature (IAT) measurement in forced induction Coyote 5.0 L engines from 2011–2014. It lets a second IAT sensor (IAT2) tie directly into the factory ECU, bypassing limitations of the stock MAF/IAT setup. For anyone building a supercharged or turbocharged Coyote motor—especially using VMP, Whipple, Kenne Bell, or PD blower systems—this harness enables accurate temperature measurement in the manifold, which is critical for safe tuning and maximizing performance under boost.

Key Features

  • Adds a dedicated IAT2 circuit tied into the stock ECU for manifold temperature monitoring

  • Plugs inline with the MAF wiring harness to bypass the factory IAT within the MAF sensor

  • Designed for forced induction setups (supercharged or turbocharged) on 11–14 Coyote motors

  • Compatible with VMP, Whipple, Kenne Bell, PD blower systems (in non-factory ECU configurations)

  • Requires calibration support (the MCT switch must be enabled) for proper operation

  • Rugged wiring construction, sealed connectors to withstand engine bay conditions

Benefits

  • Enables more precise tuning under boost by measuring intake charge temperature at the manifold, not just at the MAF

  • Helps prevent detonation, mis­tuning, and knock by delivering more accurate temperature data

  • Adds flexibility for high-boost or high-charge systems where air heat soak is significant

  • Minimal wiring upgrade—no major rework or harness overhaul

  • Backed by standard warranty (check warranty duration with the manufacturer)

Product Specs

  • Part number: VMP-SUP066

  • Color: black (wiring loom) with OEM-style connectors

  • Material: automotive-grade wire with weather-resistant insulation and sealed connectors

  • Connector types: MAF inline connector + IAT sensor connector

  • Length: sufficient to interface between MAF harness and ECU tie-in point

  • Weight: lightweight (few ounces)

  • Operating environment: rated for engine-bay temperatures, vibration, and heat cycles

Install Difficulty level
Installation is straightforward and approachable for any DIYer with basic wiring experience. Most users report completion in under 30 minutes (splicing inline the MAF harness, mounting the IAT sensor in the manifold, and plugging into the ECU). The design keeps the install clean with no major disassembly required. Calibration (enabling the MCT switch) is the only software step, but that’s standard in forced induction tuning.

Vehicle Fitment
Fits Ford Mustang and Ford F-150 models equipped with the 5.0 L Coyote engine from years 2011 through 2014. Applicable to both naturally aspirated and forced induction builds, though the harness is especially useful in supercharged or turbocharged applications (SC/Turbo) that tie additional IAT sensors to the stock PCM.

CARB / EO Status
This product is not CARB approved and is not legal for sale or use on pollution-controlled vehicles in the state of California or other CARB-regulated regions.
