Default EZGO RXV won't release brake after Danaher to Curtis Conversion

Yesterday, (Sunday) I changed out the old Danaher controller to the EZGO 350 Curtis Controller on 2010 RXV fleet cart. Now cart won't go.

Symptoms:

Turn on cart, Cart Jerks
Brake Lights always on

Conversion Instructions said to splice into white wire which is supposed to be from motor brake. Unfortunately harness to motor has two white wires. Tried them both. The only difference is the violence with which cart jerks.

Borrowed Curtis Handheld, model 1313 programmer.

Handheld & controller communicate just fine. It even allowed me to set the cart into freedom mode and max out acceleration and top speed.

Depending on which white wire I tap into; Handheld will show the following errors:

1206AC-5360 Throttle Wiper & 1206AC-5360 Brake Wiper

Switching to other white wire Handheld will show only:

1206AC-5360 Throttle Wiper

According to Troubleshooting & diagnostics, both errors indicate:

Brake [or throttle] Pedal input voltage outside active range

Controller response:

Shutdown Throttle

Which is what the cart exhibits....

Why would a controller change cause this condition? Pedals were fine Saturday.

Putting cart into tow mode frees up the break and I have no issues pushing it around.

PS I've looked through the older posts with the last one being in 2016. They're similar, but not identical to this.
