Switch to OBDI, now fans won't turn off

I was wanting to switch to a OBDI so I got a pcm and the OBDI knock sensor. I installed the knock sensor and the pcm. When I cranked up after 5-10 seconds the fans came on and stayed on for however long the car ran.

Does anyone know what could be a possible problem?

My fan is wired up so I have to flip a switch to turn it on or off, there is no automatic function. Could this be causing trouble?

Any help or suggestions are appreciated.

What kind of program do you have in that OBDI pcm? Are you sure it's the right one for your car?

It was a stock program 95 6speed pcm.

You're most likely getting some code or something. Get it scanned.
