i see on the rambo board + - for extruded so does that mean the heat resister has a + - direction i did not see any markings on the resister, better find out now before i tune this thing on lol

No it's just a resistor, they just mark the outputs in case you're driving something that cares, some fans do.

For example, the Onyx heated bed cares. The heater is just a resistor, but the indicator LED needs correct polarity.
