Pin 2 White with Yellow stripe
Pin 4 Tan with Light Blue Stripe
These both come from the driver's side "master control" switch.

I am not sure if I understand "continuity".....to me it means low resistance between the 2 points mentioned.
Check to make sure that you have +12 Volts on Pin 3 (pink) using Pin 6 (black).
If you do not have this, then you will not get voltage on the other measurements.

When you toggle the switch....you will apply +12V to one side of the motor and ground to the other.....then when you toggle the switch to the other direction.....you will be simply switching which motor leads have the +12V and ground....to make it run in the other direction.....so where you measured +12V in the first position, you will measure 0V.......

Now.....I have a Radio Shack DMM.....that was very inexpensive....and the sample time is a couple of seconds......much slower than the more expensive Fluke DMM that I use at work......so I thought that I had no voltage.....but it ended up being the slower sample time of my meter.
Holding the switch for too long will blow the 30amp fuse.
One could use one of those test lights that they sell at auto part stores also......make sure to use one designed for Automotive.....and NOT one intended for household use (A/C, and higher voltage)......and then, don't use the automotive one for household use....unless it specifically says that it can be used for such.
