Product Details

Features

  • 18" extension relocates your MAP sensor for Velocity intake clearance
  • LS3-style 5-wire female connector on both ends — same style, no conversion
  • Fits Gen IV MAP sensor (GM #12592525) used with TSP Velocity intakes
  • Compatible with LS3, LS9, and LSA MAP sensor applications

Description

This MAP sensor harness extension is designed to help complete a Velocity intake installation by giving you the extra length needed to relocate the MAP sensor. It uses an LS3-style 5-wire female connector on both the harness and sensor side — this is a same-style extension, not a converter between different sensor generations.

It's built for Gen IV MAP sensors, including GM part #12592525, the sensor sold with TSP Velocity intake manifolds. At 18" in length, it gives you room to reposition the sensor away from the intake for clearance, without changing the sensor's plug style or wiring.


Applications
Fits Chevrolet Small Block V8 Gen III/IV (LS-based) applications at 6.2L/376 in³. Works with Gen IV MAP sensors found in LS3, LS9, and LSA applications — including GM #12592525, the sensor sold with TSP Velocity intake manifolds.

Installation
18" black wiring harness with a female LS3-style 5-wire connector on both ends. Sold individually. Confirm your MAP sensor uses the LS3-style 5-wire connector before ordering, since this extends that connector rather than converting to or from a different style.

Q&A

Does this convert an older MAP sensor to a newer style?
No — this is a same-style extension cable. Both ends use the LS3-style 5-wire female connector; it doesn't change or adapt between different sensor generations.

What sensor does this work with?
Gen IV MAP sensors, including GM #12592525 — the sensor sold with TSP Velocity intake manifolds — and sensors used in LS3, LS9, and LSA applications.

How long is this extension?
18".

Why would I need this extension?
To relocate the MAP sensor for clearance when installing a Velocity intake manifold, without changing the sensor's connector style.

Is this sold as a single cable or a set?
Sold individually.
