MCP-350 Pinout

post #1 of 5
Thread Starter 
I bought an OEM MCP-350 and I want to terminate it to a fan header so that I can connect it to my t-balancer bigng, but I am not sure which wire is which. I don't want to short the pump out so I took this picture hoping someone could tell me which wire is which. Thanks to anyone that can help.

My DDC 3.2 PCB is completely different, but here is a picture anyway. At least on my model, the typical wire colors are standard. (Ground, 12V, RPM sensor, 12V bridge)

A couple more from Skinnee:

The one on the far left is the new MCP35X PWM variety where green is the PWM sensor wire, middle is I believe the DDC 3.25 and right is DDC 3.2.

There have been a ton of variations, pretty hard to tell.

I have really no idea on yours, maybe looking at the traces on the underside may help, but I'm a greenhorn when it comes to electronics.

The best thing I could think of would be to run it where you took it from and probe the wires with a multimeter. A multimeter with Hz/Duty capability could pick out the RPM an PWM wires if it has those.

Or if you bought it from someone, ask the seller...he should hook you up with the pinout details.
