OK, I followed these instructions with the white (control) wire not connected which should have been 30hz? The car started and ran for about 20 seconds, cut off, then would not restart. I connected the white (control) wire to ground which should have made it 50hz? no start, I then switched the two white wires connecting the "control wire to the Dk blue with the other white not connected, no start, I grounded the other white wire, no start, I connected both white wires to the dk blue... no start
VATS bypass module wires:
Red: 12V ignition of accessories
White: Fuel enable wire. 50hz or 30hz.
White: Control wire. Connecting this wire to the Ground will produce Standard Vats Bypass signal (50hz)
on the signal White wire. If this wire is not connected to the ground the White signal wire will produce
older 30 Hz VATS signal used on some 90-93 PCMs
The VATS bypass wire, White (adjacent to Red wire), should connect to VATS fuel enable wire (circuit
number 229) usually a dark blue wire at the PCM, position varies depending on application: LT1, LS1 and TPI.
Typically found on Pin 25 or 30 on the red connector or Pin 55 or 70 on the Blue connector, of found on B6
