Db25 Wire Color Code
For example, DB-25 denotes a D-sub with a 25-position shell size and a 25-position contact configuration. The contacts in each row of these connectors are spaced 326/3000 of an inch apart, or approximately 0.1087 inches (2.76 mm), and the rows are spaced 0.112 inches (2.84 mm) apart; the pins in the two rows are offset by half the distance.

DB25 (D-Subminiature) Cables are available in a variety of lengths and have guaranteed color codes. The heavier gauge wires (20 AWG for the last four wires and 24 AWG for the remaining wires) allow the user to easily terminate the wires into standard terminal blocks. DB25-MFP Double-ended. Pin 2 on standard DB-9 and DB-25; TX (Transmit) - connected to RX on the other end. Pin 3 on standard DB-9 and DB-25; GND (Signal ground) - Pin 5 on standard DB-9 and pin 7 on standard DB-25 (Note that sometimes particular serial cables are wired in non-standard way, but this is very rare. Indeed, there is a number of possible serial connectors). DB-25 connectors are commonly used to carry analog signals for beam displacement and color to laser projectors, as specified in the ISP-DB25 protocol published by the International Laser Display Association. Wire-contact attachment types.
I have a furnace blower that I plan to use just as a high powered fan. It's
a rather small squirrel cage direct drive blower.
I am assuming that the black wire is hot, and the white wire is common. And
then there are three colored wires that I'm assuming are LO, MED, HI
jumpers, but I don't know what they are to be attached to?
I have a Red, a Blue, and an Orange wire. Suppose that the red is HI and the
blue is MED and the orange is LO (just as an example)....does that mean that
the color of my choice needs to be contacting the ground/common or the hot?
I don't understand the theory behind these wires.
Also, there is a capacitor with two terminals on it mounted on this unit.
Both terminals have a brown wire that goes directly into the motor.
The ends of all these wires, including the black and white have just been
cut off blunt, and of course there is no wiring diagram attached to the
blower.
My main question is not to determine which color is which speed, I can
figure that part out on my own *if* I knew to what that wire was to be
attached? Common/Hot?
Thanks
Bill
