Stock dual fan
On the back of the fans, which is the + and - ? I bought a wiring kit from Summit and am installing it right now. I didn't know if it would run or not if I had the terminals reversed. I also didn't know if the fans would reverse flow if the terminals were backwards.

There DC if you reverse them they will push air into the radiator instead of pull.

Re: Stock dual fan
Do you still have the old plugs? They only go in one way. See which way they go in and what side the black(ground) wire is on. Other one must be positive.

Re: Stock dual fan
You want them to blow air towards the motor. Whichever way that is. I upgraded and sold the stock fans a long time ago.
