HFS3v2 water meth for 335i
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?  |
