ATF Warning light issue and info

[contactbrew@hotmail.comt]

Hi I have a 1994 KZN130 Auto and the ATF oil temp warning light comes on most of the time when I press the brake. It's clearly nothing to do with the oil temp but just a wiring issue somewhere. Has anyone had this issue before or can you recommend how I solve it.......Also where is the ATF temp sensor on a KZN130

Temp sensor is on the outlet pipe (nearest to bellhousing) on the transmission.
