Where does the ground come from on a terminal 85?
RE: Terry, The terminal 85 is the ground coming from the PCM. It relies on the inputs from the low pressure and high pressure switches and control module. I would feel more comfortable knowing the operating pressures before I tell you to replace the PCM.
Which is terminal 87 and 30 on a Chevy Silverado?
RE:Max, 30 is the wire that has 12 volts to it from the A/C 10 amp fuse, take a jumper wire and touch it to the dark green wire (87) and the compressor clutch should engage. Yes you can jump the wires while the engine is running. Which ones are terminals 87 and 30?
How many terminals does a fuel pump relay need?

What are terminals 86 and 85 in a relay?
Relay Terminal Identification Terminals 86 and 85 are the primary side of the relay, which utilizes an electromagnet to close (connect) the secondary electrical circuit inside the relay. This electromagnet is activated by a simple power (+) and ground (-) much like a light bulb circuit.

What kind of wire is used for terminal 30?
The wire connected to terminal 30 is a 4.0 mm wire which is designed to carry full current demanded by the fuel pump, DME, and fuel injectors. I strongly recommend using terminal 30 instead of terminal 86 to supply power via the jumper. The emergency jumper consists of three leads with male spade connector on each lead (shown below).
What kind of battery jumper do I Need?
Red brass core battery jumper terminal, also known as jumper bushing. Allows electrical current to pass through panels and barriers, so you can mount it anywhere on your vehicle, hook-up to battery cable, and connect to the battery for jumping or charging.
