#190388 - if it is 12V hi/lo and less than 200mA
Responding to: Chico Magalh„es's previous message
'any' transistor will do. NPN or PNP you have to find out if the input is pull-down or pull-up. meassure the input wit nothong connevted, if it is 12V you need pull-down, if it is 0 you need pullup. then use you ammeter to pull it up or down and you have the data you need
