Hey guys just bought a 99 mustang v6. I seem to be having several electrical issues. Thinking they may be connected. Had the radio working last night but no display. Now it won’t come back on. Check engine light has came on and off several times. The digital odometer is sometimes visible and then sometimes it’s not. Are these connected? Any ideas?

 

so been working on the car, I replaced the radio with another one and it works. engine cel seems to be related to an issue im having where the car dies when stopping. I cant figure that out.

 

Honestly, just take it into a mechanic at this point. It will save you time and money in the long run. They have devices that will pin point the problem directly.
