BMW 335i HFS-3 power problem
Hello Everyone,
I bought a used kit and want to know if i got ripped off. I have a hfs-3v2 and i started to hook up everything. I have hooked up everything except the ecu/user plug. I wanted to know if the unit should be on? for example the lights on the gauge. I have power at the power plug. 12v red Ground - black and white 12v head lamp switch- purple Does that mean i need to have but a new box unit? |
