Power steering replacement instructions needed

Okay, so I got the old one off and the new one on. I followed the manuals steps on bleeding the lines and at first it was hard and tight but eventually it went back to normal, but I could still hear a slight winding growl sound. So after all this I go to bed and got up just now and all the fluid is on the ground under my truck mostly where the pump and reservoir area is. So what now? Do you think maybe somethings not on right or the hoses or lines in that area are messed up? What are you thoughts now? Please. By the way, remember this is the second pump in six months. Now I replaced the power steering switch and its harness with generic. Though changed the drive belt the reservoir because I lost my lid to the old 1. Other than that no parts changed connect to it.

I didn't remove any of the lines I only disconnected them at the eye bolts and replaced the copper washers on both ends. The only hose I took off is the one from the reservoir. Can I use any fluid or does it have to be Nissan?

Okay, so another update and some pics. So after goin out yesterday I open the hood and all the fluid was all on the ground from the other night. My reservoir was actually still at the max line so I get under it and that line that has the eyebolt and has like a rubber tubing around it. Well where it connects to the rack and pinion appeared to be leaking some from around the bolts that connect it. So I tightened them or I think I did at least and it also looks like the reservoir which I replaced because I lost my cap to the old one may of leaked also. But on the reservoir are 2 hoses 1 going down to the pump and 1 going towards the radiator area this hose looks like it may of touched something hot at some point or maybe it's just old. I don't see any other spots that appear to of leaked. I'm going to go out and see if the steering wheel turns and makes noise. Oh, and I did notice that my steering wheels now actually going into the lock position when the cars off, as it wasn't before the new pump was installed. Here's the pics tell me if this hose from the reservoir and what I think is the line connector should be replaced or not I have to take a better pic of the hose.

Okay, so I went out and started it up and it's leaking from the power steering switch. The one you screw into that metal line with the eye/banjo bolt and remember I had to replace it after the original person broke it off with part inside the the hole and the other part at the harness connector. Which I had to replace because it wouldn't separate from the plug. Both were not replaced with the Nissan brand but a way cheaper brand. Would this cause it to leak? I'm going to try to attach a video of how its coming out to show you. Can I drive it now or should I wait until all leaks are stopped first. Scratch the video can't get under it enough. But I can see the tensioner pulley moving when it's running. So i'm guessing I missed some bolts when reinstalling the pump. So i'm going to check this out and let you know later. Thanks

Okay, so new update: I have managed to get everything put back together. However, the leak is actually coming from the power steering switch that I replaced. However isn't there a gasket that goes onto it where it screws into the car? If so mine is missing. So do they sell just the gasket or do I have to replace the switch again all together? Btw this is the only place I can find leaking.

Yes that's it and dang it I ordered another one already because I didn't think I could buy one by itself.

Okay, so I got the new one today i'm about to go install it, but I can say this is a much better made one than the one I have in it now. So I will update again when done.

Do you know what this goes over? The person that caused all of this removed it from somewhere and I cleaned it up, but can't figure out where it goes to.

I can't find where it bolts back onto my truck but I'm still leaking fluid its ether from the psp switch or somewhere above it but not at the reservoir but I cant figure out where here's a video though. Let me know what you think. It's not making the whining noise as much, mostly when I'm bleeding the lines and turning it all the way one way or the other. My kid said it flows more when turning the wheel in one direction verses the other. What's your thoughts now? Because i'm begining to feel defeated.

Could it be the harness to the switch it was replaced with a aftermarket one or the line it screws into? I have read a lot of complaints with this issue only no results were given just my luck.

Okay, so what's your suggestion? It's such a tight fit up inside there but could it be coming from the line then I don't know what else to try. But I know last night when I turned the wheel it came out of wherever quicker and emptied the reservoir but it hadn't emptied it before. Let me know what your thoughts are to try next. And details if any on how to do what you suggest, please.
