Sorry I didn't see this. Put the box on the floor. Its the best place for it. There is a resume switch on the joystick (green one). It can be used for sure. Not sure about the 155 but on my 150 there was a pined connected labeled P27 or something...I can go look if you need to, the dealer also should know. Then you can run a wire to pin 10 and 11 on the control box, will need a printer cable or can splice the wires of the ones that go to foot pedal if you have one. If you need more info let me know, I will be pulling my unit out of shed in a couple days and can take some pics.
