Okay i went today for a small ride just to find out that my wipers wont work,i did connected the wiper harness(unwrapped from the original harness and plug them back in)but they do nothing is like it does not have any power at all,Do i need to add a ground or power wire to the wiper motor somehow?Please help me!

 

No need to ground it. Did you have problems before you installed the standalone. I used to have problems with the switches to get the parking lights to work. I am assuming the other side of the swithches could also go bad.
