Wiring Help!

[campground man]

I currently have a 89 Pulsar and a 90 Sentra 4 door sitting in my driveway...I pulled both motors and plan on putting the sentra's 1.6 L into the Pulsar since it's 1.8 is blown so I can sell the Pulsar.

I'm also putting a 1.8 CA18DET into the sentra using the 1.8 Ca18DE harness from the Pulsar.

What I noticed is that the body harness on both cars have different plugs - with the Pulsar having 26 wires and the Sentra having 33. I need a wiring diagram or information on the two so that I can wire back in the engine harness after the transplants...Also, I need to know what do about the difference in the number of wires?
