Tail light woes

[stangbring]

My tails and my brake lights were not working but my blinkers were (well both at the same time no matter which way I put them on).

S0, I rewired the rearend and the same thing is happening, BUT. When I lean on the left rear the lights come on, the harder I lean the more they come on. Seems that I have a ground problem. I am just not sure where?

My battery is grounded good and all my other lights and stereo and everything else works great.

I thought maybe the bed was not bolted on good, but it is, not sure what else to check.

Any ideas would be appreciated.

Thanks.
