Right front parking lamp turns on with underhood lamp

[95vrt6266]

Hi everyone, I recently picked up a new to me 2001 ram 2500. The truck is a 2001 non sport 2500 qclb 4x4 auto. I bought the truck a few weeks ago seeing as it was pretty well maintained with very minimal rust. This is the only electrical problem on the truck. 

The right front parking lamp does not work with the lights on causing the right blinker to blink fast and cluster has the right signal illuminated with lights on. Its not the bulb or socket. I noticed when i opened the hood when the underhood light comes on so does the right front parking lamp. How can this happen?

you have a wire that is shorting.  

 

Get a multimeter out and start casing wires

for a 99 but it should be close

Might check the grounds for both the under hood light and the turn signal might find out it's the same one (guessin').
