Need some fan wiring help

Im wiring 2 electric pusher fans and I would like to use the stock relays for the AC fan. I just needed a little help on how to wire this up. Can I just wire the positives from both fans to the lo fan relay? Does the plug that attaches to the stock fan have a ground? Looking over the FSM I see that there is a wire for the lo and one for the hi but it looks like the other 2 go to the ecu. From what Ive read the fan should come on based on the temp sensors and when the AC is turned on. I have taken AC off my car so I guess I could manually turn the fans on by turning switching the AC on.

well if you want to have to turn them on with a switch you might as well wire them directy. put a switch wherever you want, you could use the ac switch.. i think thats easier than usings relays + a lot of times the relays will blow. just find 12v and throw an in-line 30A fuse on it.

I would rather have the temp sensor kick on the fans rather then doing it manually but I also want the option to do it manually. I would like to wire it through the stock fan relay I just need some help as Im not the best at wiring.

Why not just spend the extra $40-$50 and get the fan relay that many E-fan companies sell. No guess work involved. Plus I think its safer. I know too many ppl who wired something incorrectly. Seems to be the biggest complaint I find when talking to ppl with E-fans.

Im terrible at wiring as well so another route which invlolves some work would be to buy a 3 dollar relay at autozone or etc. You will have to find a 12v switched... In my s14 i used the actual ignition. That way the fan comes on when you turn the car on and turns off when you get out.
