When my car had these issues my dash lights would flicker and at the same time the vsa eps (!) light would turn on as well as my radio cutting off.
If it was at night and my headlights were on with the ac on the car would sometimes stall while driving while doing all of the above things. It was a nightmare

I opted for a after market battery cable because it was a 2g wire but I am sure a oem one would work and should cost around $12-$15 at your local dealer

Here is my thread with a lot of info as well as more detailed explanations of what I was experiencing https://www.s2ki.com/s2000/topic/110...ter-lights-up/
