Where does the power go in a psi harness?
• The 2 black wires with the large ring terminals provide all the power to the harness. They get connected to the large stud on the starter, which should have battery power. WHY DON’T MY OXYGEN SENSORS PLUG IN? • PSI harnesses are designed to use the most popular Oxygen sensor applications.
Can a speedometer be wired to a psi harness?
• No, at no time should you tap into any of the engine sensor wiring supplied with your PSI harness. You speedometer should be wired per the manufacturer’s instructions. This typically requires that you connect the speedometer to the output wire supplied with the PSI wiring harness ‘under dash wiring’ section.
Can a psi harness be used as a temperature gauge?
• No, at no time should you tap into any of the engine sensor wiring supplied with your PSI harness. You temperature gauge should be wired per the manufacturer’s instructions. This typically requires the sender that came with the gauge to be used. HOW DO I ENSURE THAT MY COIL SUB-ASSEMBLY WIRING HARNESS IS ON THE CORRECT SIDE?
What kind of wire do I need for my LS controller?
• Connect our white “under dash” wire to their green wire of your tachometer. Note that most aftermarket tachometers work with a 12-volt signal. However, LS controllers use a 5-volt signal which is not directly compatible with most aftermarket tachometers. In these cases a resistor must be wired into the tachometer signal wire.
What is a harness connector?
A Harness Connector object is an electrical drawing primitive. It is essentially a container to group various signals together to form a Signal Harness including buses, wires, and other signal harnesses. A Harness Connector is defined by the Harness Type.
What is 7 pin harness?
The 7 pin “RV” plug includes brake lights, running lights, turn signals, powered brakes and back up lights. The 4 pin harness just has brake lights, turn lights, and running lights.
What is a trailer connector?
A trailer connector is a multi-pole electrical connector between a towing vehicle such as a car or truck and a trailer.
Where are the low and high AC pressure switches located?
The low-pressure side switch is found before the AC compressor, while the high-pressure switch comes after the compressor. Most AC pressure switches are found within the engine compartment, but some manufacturers put them elsewhere. A look in your service manual will show you the appropriate location for your model. AC Pressure Switch Function
Is the Ford a / C cycling pressure switch harness compatible?
Easy to solder on properly to the old harness because the sensor/clutch AC harness disconnects from the main harness (for 2001 F-250 7.3L). Plenty of wire from the plug to work with (in fact I trimmed it down a bit before soldering).
