I think the connector is different. The Fiero uses a square connector and it mounts in a slightly different location. I just transfer the wires from my old fan. I don't remember which year/motor the correct fan for our cars comes on. A lot of Fiero's use the standard small round motor.Is the fan from a fiero exactly the same? Same plug and mounting locations etc etc?
I removed these from my car. I took them off because of a large voltage draw on my electrical system. I had a set of LS1 fans laying around that I was going to install on my Trailblazer SS (traded for a Tahoe) but never did. I used the wiring harness that I had purchased for the install on the TBSS. Now It draws about .02-.05 volts with both fans running.One thing I noticed with these fans is that they draw ALOT of power. So much power that the OEM plug actually started melting because the stock ground is not big enough to support them. I upgraded the ground to heavier wire and havent had an issue thus far.
