Turn Signal Ground Locations

I have a 1989 3.2 Carrera and the right hand side turn signals (both front and rear) blink twice as fast as the left. I have swapped bulbs, checked the sockets, everything seems fine. After looking at the Bentley diagram (and reading a bunch of posts on the topic), it seems the most likely culprit left is the grounds. Can anyone tell me where to find them and how to access (do I need to pull the front bumper, etc)?

Thanks! (sorry, didn't find anything using the search specific to the actual ground locations)

I already did that (and messed with the sockets in case the bulbs were loose). My understanding is that a bad ground could do this as well, so looking for exactly where those all are.

I would start rear light bucket and run a external ground to body. Try and scrape the paint down to bare metal. If problem still persists. Go to front. It's a little different process due to the housing is plastic. You will have to run a ground wire directly from socket. Hope this will help you find it.
