TPI Vats Module

The Painless Wiring TPI VATS Module (part number 64023) is a specialized anti-theft bypass component engineered for Tuned Port Injection Small Block Chevy engines in 1990–1992 GM vehicles. This compact module addresses the Vehicle Anti-Theft System (VATS) found on these model years, making it essential for restorers, engine swappers, and enthusiasts working with first-generation LT1 and similar TPI platforms.

Measuring 2.7 × 1.4 × 4 inches and weighing just 0.11 lbs, the TPI VATS Module integrates seamlessly into existing wiring harnesses without requiring extensive modification. Painless Wiring designed this module to work in conjunction with Tuned Port Injection fuel-injection systems, eliminating VATS detection errors that commonly occur during engine conversion or restoration work. The compact form factor allows for discreet mounting in the engine bay or behind the dash without interfering with other electrical components or engine management sensors.

This module is ideal for builders performing LS or LT1 engine swaps into second-generation Camaros, Firebirds, and F-bodies, as well as for restoration shops preserving original TPI architecture while modernizing electrical systems. The VATS bypass functionality prevents security system faults that would otherwise trigger fault codes or prevent the vehicle from starting, streamlining the integration process and reducing troubleshooting time on the dyno or during test drives.

Sold as a single unit, this Painless Wiring VATS Module is a direct-fit solution for the specific GM VATS architecture of early-'90s TPI platforms. Engine builders and restoration specialists recognize Painless Wiring as a trusted source for custom wiring harnesses and electrical integration components, making this module a reliable choice for authentic TPI engine work.
