ohc temp reads 75°

Just installed a ZJ ohc using a minivan frame into my 97xj. Everything works great besides the outside temp. It reads 75° no matter what... Its a brand new sensor as well. Could it be that the two temp senor wires need to get switched to the bcm connecting wires? I wasn't sure if they had to go to any wire in particular of the two...

Well I'm stuck as to what the issue is. I got a new plug and sensor and plugged it directly into the bcm... Still reads 75. Could it be a bad bcm or something else ?
