DESCRIPTION:
These progressive linkage, 4-barrel throttle bodies are designed for use with most aftermarket electronic fuel injection systems. They bolt
directly to standard square-bore or 4500 series carburetor mounting flanges and feature a Delphi/GM IAC motor (Stepper Type) or a Hitachi
Linear IAC motor (Pulse Width Modulated Type) (See “APPLICATIONS” below).
APPLICATIONS:
Catalog #3862, 3863, 3878, 3879, 3888, 3962, 3963, 3978, 3979 & 3988
These throttle bodies are designed to work with a Delphi/GM IAC (Stepper Type)
(See Figure 1)
. Refer to instructions provided with the ECU being
used or contact the manufacturer of your ECU for pin locations and signal output. The Throttle Position Sensor (TPS)
(See Figure 3)
mates with
a GM style connector (Packard Metripack part # 12065287 or 12052895). Refer to the instructions provided with the ECU being used or contact
the manufacturer of your ECU for pin locations and signal output.
1.
Install throttle body on intake manifold using standard carburetor mounting hardware and the supplied gasket.
2.
Connect IAC motor and TPS sensor to the appropriate connectors on your wiring harness.
3.
Throttle cable mounting may vary, so a throttle cable bracket may need to be fabricated. Throttle cable and bracket are not included.
(For Chevrolet applications, Edelbrock offers a variety of universal throttle brackets, see catalog or website for details.)
