Chevrolet Performance DR-525 Serie Manuel D'instructions page 6

NOTE: When connected to the GMPP Supermatic Connect and Cruise Harness the pull up resister is not required for the Transmission Controller.
•
An oil pressure output is included in the bulkhead connector and can be used for a pressure gauge if desired (see below for scaling).
•
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 and the T56 Super Magnum Manual Transmission) for this to function.

Bulkhead connector outputs - Terminals for the included mating connector can be acquired at a GM dealership in the Delphi
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 Service Desk.
•
GMLAN Communication Link (TAN/BLACK STRIPE [+], TAN [-]) – 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. Can be used with a LAN dash or an electronic dash readout display.
•
Tachometer Signal (WHITE) – This is a 2 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.
•
MAP (LT GREEN) – This is an output for use in gauges or for load indication in transmission controllers (any connection must be to high-
impedance device). The output is a 0-5 Volt signal ranging from 10 – 105 KPa (1.5 – 15.2 psia). Use the ground wire in the bulkhead
connector as the low reference (ground).
•
Oil pressure Sensor (TAN/WHITE STRIPE) – This is a zero to five volt output function from the oil pressure sensor which can be used for
monitoring oil pressure is (Pressure (psig) = [32*Sensor Voltage]-16) See Chart Below. Use the ground wire in the bulkhead connector as
the low reference (ground).

Throttle Position (PURPLE) - This is an output for use in gauges or for load indication in transmission controllers (any connection must be
to a high-impedance device). The output is a 0.5 – 4.5 volt signal ranging from 0 – 100 %. 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.
