So my right turn signal is clicking really fast the front ones work but not the back right signal. I no there is a ground in the rear right tail light are there any other ground wires like this connected to this circut. I dont think there would be.

 

I had a similar problem. but it was the flasher relay under the dash. Good luck i hope thats it.

 

could be your flasher relay. Its under the dash, left side.
unfortunately there is no way to check it other than replacing it with a new one. about $18 at autozone. Double that at a local auto parts store.its a small square cube about 1" and it just unplugs.

 

Yup that was it. Luckly i got a jy around here the guy has about 30 xjs. So i got it for 5$.
