E550 electrical problems

Hello, my E550 van front/box back has an electrical problem.

Sometimes when I first start it and step on the brake my backup beeper warning goes on. Most times it stops once I start driving, but sometimes it continues for a while or comebacks back by chance. Doesn't matter where the shifter lever is, park, reverse or drive.

Yesterday it woke up really bad and anytime I used a turn signal or flasher I got a fast blinker and beeper going. Figured I had a light bulb out. Looked around the truck and noticed no taillights. Shut truck off went inside a building with flashers on, beeper was going. When I restarted, beeper stopped and I had right side taillights but no left Drivers side.

Drove back home still no left side.

Have no idea where to start looking. Electrical is not my strong suit.

Any and all help appreciated.

My first thought would be to check your grounds on that left side.

You've got a feed back issue because of a bad ground, there should be a ground wire connected to the rear of the left frame rail, it's probably corroded.

Figure Id throw this out there too. Since I will be looking around the rear tail lights, my tail lights are really low, under the lift gate. I was hoping to add more lights high up on the box frame. Found some nice long led lites that fit well. Which wires (color) on the brake lites coming out of the lite boxes would I tie into for brake, turn and nite lighting?

I strongly recommend that you fix your current electrical issue before you start adding more lights.
