I made the jumper bypass for the MBR that allows you to backup without snowblower shutting off. Does this work on 2018 models? It's not working for me and was wondering if there is something else I should be doing. I tried unplugging snowblower elec connector and it still stalls when I put in reverse with blower on. The wires on the connector are red and yellow. I did use the connector I made sold on amazon it didn't work so I stuck a piece of wire into plug for temporary try and it didn't work either. Here is a pic of red and yellow wires on the plug. Any help would be appreciated.Should my lever for PTO selection be in the mid or rear?
