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.

  • Vats Bypass - Works Great
Worked perfect. Used to bypass VATS signal to ecu for fuel on 91 Camaro which used the 30 hertz signal. Install was easy and it functioned as intended.

  • Get a chip made
I bought this module for a 1991 F-body with an injector pulse issue and there are absolutely no installation instructions for the module whatsoever in the package. I then checked their website and talk about vague. The directions read that the fuel injector wire will be in the harness at F10 for TPI cars which would be great if there actually was an F10 in the plug. It then basically says if it’s not F10 it could be this one, or that one, or maybe even that one. If the manufacturer did the research and sent a diagram with their product I could justify the price but for $25 going into the garbage can I’m a bit disappointed. ... show more

  • 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

Ignore the obnoxious directions on the web and just try all of the frequencies. It works.

  • Don't waste your money, quit working after 2 days
This companies products used to be good but the ones they are making now are pure junk, and a waste of money. Bought two of these in the last month that died after less than a week of use. One won't power on at all, other one flashes LED light it's powered on bit has been verified with oscilloscope to have no output too fuel enable circuit. Absolute waste of time and money. ... show more
