1994 mustang am wiring a aftermarket 2 wire fan to be controlled by my ecm. Is it possible to wire the low and the high speed wire to the positive wire on the fan and have the fan run on low and high speed controlled by the ecm or will I have back feed problems? If need be I can I just wire it to the high speed power wire and tune the computer for the temp I want it to turn on?
