I have installed a radio into my car, when car is off (no key) multimeter shows 200 milliamp, when I unplug harness from radio it drops to 30 milliamps. I've looked at everything I have read to look at and can't figure it out please help

So your battery is dying overnight? For parasitic draw, Anything over 50 mA in older cars and 85 in newer cars is considered excessive. Is the radio turning off also when you turn the key off? Assuming it wasn’t doing this before the radio install.

Bought without a radio harness was cut. Yes it turns off when key is off

All I can say is to double check all your wires are in the right spot since the harness was cut. If it’s still drawing too much, maybe a friend can let you try another radio to rule that out.
