6.2 Vacuum Line Connections
1. Connect the vacuum lines that were previously disconnected. Figures 9 & 10 show the function of the ports in the STEALTH
TERMINATOR™ throttle body.

7.0 FUEL SYSTEM
Connect the fuel system per the manufacturer’s instructions.
8.0 ECU MOUNTING AND WIRING OVERVIEW
The Terminator™ EFI ECU (Item 10) can be mounted inside the passenger compartment (preferable location) or in the engine
compartment. If mounted in the engine compartment, follow these guidelines:
The ECU should be located such that it isn’t being directly hit by water or road debris.
It should also be located such that it isn’t extremely close to exhaust manifolds or headers.
It should be mounted such that it is as far away from spark plug wires, CD ignition boxes, or other “electrically noisy” devices as
is reasonable possible.
Make sure the connector end of the ECU is pointed DOWN such that water can’t make its way into the ECU terminals.
The ECU comes with mounting hardware (stainless steel screws and nuts). The ECU has plastic shoulders on the mounting ears. DO
NOT REMOVE THEM. Do not over-tighten the mounting hardware if the ECU is not mounted on a flat surface.
EFI systems depends heavily on a clean and constant voltage source. ALL grounds of an electrical system are just as important as the
power side.
TERMINATOR™ ECU’s contain multiple processing devices that require clean power and ground sources. Wiring harnesses must be
installed in such a manner that they are separated from “dirty” power and ground sources.
DO’S
Install the main power and ground directly to the battery. To the POSTS/TERMINALS, not to any other place.
Keep sensor wiring away from high voltage or “noisy/dirty” components and wiring, especially secondary ignition wiring (plug
wires), ignition boxes and associated wiring. It is best that the plug wires not physically contact any EFI wires.
Properly crimp or crimp and solder any wire connections. Apply quality heat shrink over any of these connections.
Ensure that the engine is properly grounded to the negative battery post/terminal, as well as chassis.
DON’TS
NEVER run high voltage or “noisy/dirty” wires in parallel (bundle/loom together) with any EFI sensor wiring. If wires need to
cross, try to do so at an angle.
Don’t use the electric fan outputs to directly power a fan. They must only trigger a relay.
Don’t use improper crimping tools.
Don’t use things like “t-taps”, etc. Use proper crimpers/solder and heat shrink.
It is never recommended to splice/share signal wires (such as TPS, etc.) between different electronic control units (i.e.
“piggyback”).
Don’t connect the red/white switched +12V wire to “dirty” sources, such as the ignition coil, audio systems, or 12V sources
connected to HID head lamps.
NEVER start an engine with a battery charger attached
9.0 WIRING HARNESS INSTALLATION
The STEALTH TERMINATOR™ throttle body comes with sensors pre-wired for easy installation. The illustrated diagram below (Figure
11) is intended as an overview of how the system should be wired. Remember, the main ECU power and ground must be connected
directly to the battery post/terminal AFTER all other wiring installation has been performed. Do not attach the loose white or yellow wires,
or ignition connector until you have referred to section 10.0 (Ignition Wiring).
