• 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 (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.
• Ground (BLACK) – This is used as the low reference (ground) for
completion of the MAP, TPS, and oil pressure output circuits. It can
also be used for modules connected to either of the fused 12V outputs.
Terminals for the included mating connector can be acquired at a
GM dealership in the Delphi Terminal Service kit (J38-125) in tray 8
position 9. At most dealerships this can be found at the Service Desk.
NOTE: If you are using CP Supermatic Transmission Controller Kit,
#19212657, the Tachometer Signal (WHITE) and Throttle Position
(PURPLE) are required to be connected. If you are using CP
Supermatic Connect and Cruise Kit, #19257634 or 19257661, the Bulk
Head Connector must be plugged into the CP Supermatic Connect
and Cruise harness. For the Connect and Cruise, the tachometer
signal and the throttle position signal are received through the bulk
head connector.
Start-up and Break-in Procedures
Safety first. If the vehicle is on the ground, be sure the emergency brake
is set, the wheels are chocked and the car cannot fall into gear. Verify
everything is installed properly and nothing was missed.
1.
Oil & Fluid Fill: This engine assembly may need to be filled with oil
or have oil added. After installing the engine, ensure the crankcase
has been filled with the appropriate motor oil to the recommended
oil fill level on the dipstick. The 5.3L Crate Engine requires a special
oil meeting GM Standard GM4718M (this will be specified on the oil
label). Mobil 1 is one such recommended oil. Other oils meeting this
standard may be identified as synthetic. However, not all synthetic
oils will meet this GM standard. Look for and use only oil that meets
GM Standard GM4718M. Also check and fill as required any other
necessary fluids such as coolant, power steering fluid, etc.
2.
Oil System Prime: a. The engine should be primed with oil before
starting. Install an oil pressure gauge (the existing oil pressure
sensor location at the upper rear of the engine may be used)
and disconnect the engine control system (removing power from
the engine control module is generally recommended). NOTE:
Disconnecting only ignition or fuel injector connectors is not
recommended – make sure the control system will not provide
ignition or fuel to the engine. b. Once the engine control system

has been disconnected, crank the engine using the starter for 10
seconds and check for oil pressure. If no pressure is indicated, wait
30 seconds and crank again for 10 seconds. Repeat this process
until oil pressure is indicated on the gauge.
3.
Initial Engine Start: Reconnect the engine control system. Start
the engine and listen for any unusual noises. If no unusual noises
are noted, run the engine at approximately 1000 RPM until normal
operating temperature is reached.
4.
Engine Warm Up Recommendation: When possible, you should
always allow the engine to warm up prior to driving. It is a good
practice to allow the oil sump and water temperature to reach 180°F
before towing heavy loads or performing hard acceleration runs.
5.
First 30 Mile Break-In Period: The engine should be driven
at varying loads and conditions for the first 30 miles or one
hour without wide open throttle (WOT) or sustained high RPM
accelerations.
6.
Medium Accelerations for Break-In: Run five or six medium
throttle (50%) accelerations to about 4000 RPM and back to idle
(0% throttle) in gear.
7.
Hard Accelerations for Break-In: Run two or three hard throttle
(WOT 100%) accelerations to about 4000 RPM and back to idle
(0% throttle) in gear.
8.
Change the oil and filter: Replace the oil per the specification in
step 1, and replace the filter with a new PF48 AC Delco oil filter.
Inspect the oil and the oil filter for any foreign particles to ensure
that the engine is functioning properly.
9.
500 Mile Break-In Period: Drive the next 500 miles (12 to 15
engine hours) under normal conditions. Do not run the engine at its
maximum rated engine speed. Also, do not expose the engine to
extended periods of high load.
10. Change the oil and filter after 500 Mile Break-In: Again, inspect
the oil and oil filter for any foreign particles to ensure that the engine
is functioning properly.
