Pins 2 & 3 are the switch and should be made when the switch is active. The
cruise light is between pins 1 & 2. The light between pins 4 & 5 comes on
with the combination light switch. Fuse 6 in the drivers under dash fuse box
supplies power to pin3 when the ignition is on. Power is sent through the
switch out pin 2 to the cruise control unit. If you are going to service the
Odyssey yourself you should invest in the OEM service manual from HelmInc.
It has the diagrams and test information. You probably have a connector
loose somewhere in the dash.
