Anyone installed the mazda fan mod (black box)
 

ok you know that mazda kit they sell for like 70 bucks that includes the black box and harness for your fans.

Has anyone installed this with a POWER FC. it comes with no instruction and im just wondering if anyone has any hints for where the hell the blue adaptor plugs into?!?

Passenger Footwell, where the PFC is. As far as it working with the PFC, I don't know, it should. I have a custom SPAL controller.

Mazda installed this on all FDs under warranty many many years ago. If your car does not have it, then the original owner was very very lazy.

The PFC works fine with it as the mod was a jumper harness to add in the black control box.

The new engine harness does not use the jumper harness as the wiring in included in it.

ill have to post a picture and get some visual help cause im truly lost here.. i do have a brand new engine harness but it still seems to make no sense.

If I understand correctly you should not need the harness, just plug the box in to the black connector that is built into the main harness.

I have recently discoverd that Mazda screwed some owners by not installing the box saying it was not needed. Why do the fuel line upgrade and install the box after the better hoses were installed and then say some had the better hoses and do not need the box. BULLSHIT!

To install the box requires the jumper harness if the engine harness is the early original.
The later new harnesses has the two extra connectors built in.
