Description

Vats bypass module is intended for use when installing a GM engine equipped with the PASSkey I or II VATS (Vehicle Anti Theft System) into a vehicle missing the BCM (Body Control Module), or for remote start system. The VATS bypass module generates the ‘key ok’ signal normally sent from the BCM to the PCM (Powertrain Control Module) or ECM (Engine Control Module). VATS bypass module wires: RED: 12V ignition of accessories WHITE: Fuel Enable wire. 50hz or 30hz. BLUE/GREEN: Control wire. If none of the wires connected to the ground then the output is 50 Hz suitable for most of the cars. Some cars (90-93) require 30 Hz. In that case connect the Blue wire to the Ground. BLACK: Ground.

    • Works - Easy - Affordable Solution - Car Started Right Up!
I spent countless hours trying to get my car to start and run again. It's been down for several months due to VATS problems. I tried a much more expensive bypass module first and spent hours and hours trying to install under the dash only to determine I had to install using the alternate method of installing under the hood at the PCM/ECM. After getting properly connected the first device did nothing. I spent 3 weeks going back and forth with their tech person without resolution. This caused me to search for something else and I found this module on Amazon. It was 1/10 the price of the first module I tried. I figured I had nothing to lose. It came quickly, and installed in 5-10 minutes. And...my car started right up with no problems. I can't imagine a better solution. ... show more

    • Worked as advertised!
Got this to bypass VATS on my 1989 Camaro 305 TBI, got it wired in and working in less than an hour. Took me a little bit to figure out which wire to tap into but I found it!

    • Easy to install - 1995 Firebird Formula LT1
Easy to install. My son and I are planning an LT1/T56 Swap from a 1995 Firebird Formulas into a 1986 Camaro IROC. Before pulling the drivetrain out of the Firebird, I wanted to eliminate the VATS system so we could use the 1986 Steering Column and Ignition Switch (non VATS car). Did my research and decided to try this device. Using the Factory Service Manual, we located the VATS theft deterrent device under the dash and reviewed the schematic. This VATS module has five wires but for the 1995 Fbird, you only use three: Red on module goes to Pink on the connector (Switched power), Black on Module goes to Black on Connector (Ground) White on Module goes to Blue on the Connector (Fuel Signal to ECM). At the same time, you must jumper yellow/black on the connector to black so that you ground the VATS starter relay to complete the starter circuit. By wiring the the starter this way, you retain the clutch safety switch/neutral safety switch. ... show more
