4 button AUX wiring questions

Hey guys I have a 2010 6.7 I run a bale deck on it so I have a hydraulic pump that runs that. Originally I just had the basic rocker switch that ran it with the 3 wires, I was always hitting my knee on it and such. So I decided to pick up this 4 button OEM deal that fits in the slot where is usually says ram under your Jake brakes. So anyways I found a wiring diagram for it somewhere on here and hooked it up. I’m getting nothing, no lights no pump turnin on nothing but when I go back I click the 12v and the pump wires together behind the box it kicks my pump on. Did I wire it wrong? Do I have a bad 4 button box? Or is it not big enough to handle it? This is the diagram I used

You might have a bad switch box. I would use an ohm meter and check the switches. Also I would use relays to take the load off the switches.

You have the switch wired to a relay and the relay wired to the pump motor? Cant wire the switch directly to pump motor
