Vehicle Speed
A vehicle speed output is included in the bulkhead connector for use with auto-scaling speedometers. The vehicle speed sensor connector in the
harness must be attached to a variable reluctance type speed sensor (typical of most late model GM automatic transmissions) for this to function.

Bulkhead connector outputs - Terminals for the included mating connector can be acquired at a GM dealership in the Terminal Service kit. Terminals
are Delphi part number 15326269 (GM part number 19167018), and wire seals are Delphi part number 15366021 (white seal). At many dealerships
these can be found at the Parts Department.
GMLAN Communication Link (LT BLUE [+], WHITE [-]) - This provides the GMLAN communication messages containing engine operating
parameters for potential use in future add on modules – any current integration of this is left to the user. This may integrate with a LAN dash
or an electronic dash readout display.
Tachometer Signal (WHITE) - This is a 24 pulse/rev output (see features above).
Vehicle Speed (BROWN) - This is a non scaled output for use with auto-scaling speedometers and will not function unless a vehicle speed
sensor (VSS) is connected to the ECM through the VSS wire in the harness.
Oil pressure Sensor (YELLOW/BROWN STRIPE) - This is the output from the oil pressure sensor which can be used for monitoring (Pressure
(psig) = [32*Sensor Voltage]-16). Use the ground wire in the bulkhead connector as the low reference (ground).
10A Fused 12V Power (ORANGE) - This is a power output supply and is always enabled.
15A Fused 12V Ignition Power (PINK) - This is a power output supply and is enabled only when the ignition is on.
Ground (BLACK) - This is used as the low reference (ground) for completion of the oil pressure output circuits. It can also be used for modules
connected to either of the fused 12V outputs.
NOTE: If you are using CHEVROLET PERFORMANCE Supermatic Transmission Control System kit #19302405 or 19302410 the Bulk Head Connector
must be plugged into the CHEVROLET PERFORMANCE Supermatic Connect and Cruise harness.
