6410 Park / Neutral Switch

[bub6410]

I have a 6410 that quit going forward and reverse. I changed the power reverse unit and have a new park / neutral switch to install, not sure how to wire it up since new switch has different color wires. Checked all solenoids on the tranny already, checked good. Can never get voltage on either the forward or reverse solenoid. Will have voltage on the enable solenoid until i move the shuttle in either direction then the voltage drops out. Thinking that my wiring of the switch is causing this, but have tried different wiring scenarios. Checked fluid pressure (150 psi) and pressure switch. When shuttle lever is moved to either position it just beeps. Any suggestions please.

The park neutral switch is to allow the tractor to start. There is another thread in JD AG tractors about a 6410 with the same problem. Tuned out to be a bad relay.
