My car is all apart so i cant start it and test it. Im installing a slim fan and i need it to be a puller so i have to wire it backwards. Does any one know which one is positive on the crx harness?
the blue or black.

i'm 99.9% sure black is ground. never did anything with fan wiring but every time i see a ground, it's a black wire.

usually black is ground, to be sure just twist the connections by hand, tape them up with some electrical tape and turn on the car to make sure. That way you're 100% sure before you make permament connections/solder.

 

I have the same wiring set-up, blue is positive, and black is negative. Some other aftermarket fans come with red as positive, and black as negative.

 

so blue on the crx harness is positive
