OWNERS MANUAL
Model ETM67A & ETM68A
Electronic Throttle Module for
2006+ Chevy/GMC Gas and Diesel
Engines with Automatic Transmissions
A. Introduction
This owners manual describes the InPower Model ETM67A and ETM68A
electronic throttles used on Chevy & GMC vehicles with gas and diesel
engines. Note that the ETM67A and ETM68A systems support the exact
same vehicles, but differ only in functionality. The ETM68A provides
three fast idle preset speed modes (RPM1, RPM2 & RPM3). The
ETM67A provides three fast idle preset speed modes (RPM1, RPM2 &
RPM3) plus a Charge Protect (CHRG) mode.
The electronic throttle installation requires customer-supplied control
wiring to select the required mode of operation. For example, a remote
toggle switch or a relay contact from a compressor or aerial lift circuit
could be wired to the RPM1 terminal on the electronic throttle controller
to activate the RPM1 fast idle mode. The RPM1 mode is then adjusted to
the desired fast idle engine speed rpm. Likewise, the RPM2 and RPM3
mode inputs could be wired if you need additional fast idle engine speed
functions.
The customer wiring connects to the electronic throttle module via 0.25
inch Faston terminals. The electronic throttle system is supplied with a
three foot data cable. This cable contains a 16-pin connector at one end
and 0.25 inch Faston terminals at the other end. The Faston terminals
will connect at the electronic throttle module and the 16-pin connector
plug will attach to the vehicle’s OBDII (On Board Diagnostic) data link
connector (DLC). The DLC is usually located at the lower part of the
dash on the driver’s side.
