I got a 89 bronco and I have no turn signals or brake lights I have parking lights and the fuses are good here’s the problem when I turn the key to signal the starter to start the front and rear turn signals come on and when the engine starts and I let off the key from the start position they go out and if I try to power the brake light switch the engine spins over and if I do the same with the turn signals it spins over and stops and goes again like you would have a turn signal on or the emergency flashers I was told it was the turn signal switch changed it with a used one same thing bought a new one same thing then was told it was the ignition switch changed it with a used one same thing got a new one same thing I was wondering if anyone else had this problem or should I just pull the dash and start chasing wires any help would be appreciated thank you

My credo
In theory, theory and practice are the same. In practice, they are different.
My first thought instinct is to tell you there is a bad ground connection somewhere. But it's going to take some study time with the electrical diagrams to come up with something more definitive. What do you know about the history of the truck? Has someone replaced the motor? Is there a lot of rust and corrosion that could be affecting electrical connections? Do you see evidence of a previous owner doing bad electrical work, especially under the hood?

When I got it it was just a body and frame no running gear I put early bronco axles and the engine trans and transfer case came from a 87 that I bought before I left New York and I used it till the body wanted to fall off the frame so I bought this one out of a buddy’s yard been sitting up a bit but everything worked when it was park that I know for sure I will check grounds and see what I come up with

Maybe check wiring and connections on the steering column. Seems like a connector has been repinned incorrectly or something is shorted together. The steering column is the most likely place for brake/ turn signals and ignition to get crossed up.
