To pull the tranny or not

[diplomat 1]

Hey guys I just bought a 90 300zx n/a but it doesn't run. I have heard these engine are a problem to work on but I don't mind. Anyway by the looks of it someone tryed to fix the non running issue because there are butt connectors everywhere on the wiring harness. My plans is to replace the wiring harness with another one from a friend (who is parting out his 300) and to do that I am going to pull the motor. Now I have heard that there are 2 top tranny bolts that are almost impossible to get to. My question is do I take tranny out with motor or no? I know it's possible to do it but does anyone have tips or tricks on getting to those 2 upper Tranny bolts? I am also looking into a z32 slinger to pick the motor up by is it better to get the 3 bolt or 2 bolt slinger? And one last question I found this connector cut off the car and sitting in the corner it looks like it's connected to the wiring harness on the front drivers side when I got the car it was unplugged. Any idea what this is? Thanks
