Headlights on Dimmer switch issue is on car runs rough

[87GN 98GTP]

I've swapped 2 dimmer switches and still have the issue when the lights are on the car runs rough until I turn the dimmer switch off. Any ideas

Is the BS3 directly to the battery like the instructions say? Its possible the MAP sensor is getting affected by a change in electrical load due to insufficient grounds

It's bs1 so I don't know. I will check that thanks. We hot wired the dash light to the headlights and it work fine. So maybe it's another bad dimmer. We tested the load and it barely went down

I had a first gen BS3. I got rid of it and haven't looked back. Too many weird issues with it. I run a SD2 chip now. Much better.
