You should be able to reference everything from the wiring diagram using the wire colors and the pin assignments. All of the terminals on the fuse block should be marked. Tell me where you are having trouble and I will try and guide you through it.

Expert:  Marty replied 1 year ago.

Hi, sorry for the wait I had to leave yesterday. Using the diagrams I assume you are able to place all but the middle row of wires, is that correct? If so, tell me the colors of your remaining wires.

Hi Marty. Yes, i have problem with middle row. My fuse box is all disconnect. Do you have third diagram for rest of the fuses?. i have only problem with middle row according to your diagram. If you will help me with understand it that will be great
Expert:  Marty replied 1 year ago.

Your middle row will consist of the heavy red wires, grey wires, grey/white wires, red/black and black red bundle of wires and the red/yellow wire. All of these wires should be heavier in diameter than the fuse terminal wires. If you look at the diagrams I sent you will see that the red wire feeds fuses 11, 12 and 14, the grey wire feeds fuse 13 and the grey/white wire feeds fuse 16. The red/black and black red bundle of wires feed fuses 5, 7, 8 and 10 and the red/yellow wire feeds fuse 6. Looking at the picture of the fuse box from ebay you can see that the red wires go at the end terminal. For any remaining wires you will need to use an ohmmeter to test from each middle row terminal to the fuse terminals to see which terminal powers which fuses. From there you can determine which wire goes where. For example, the grey wire feeds fuse 13 so connect one lead of your ohmmeter to the hot side of fuse 13 and probe the middle row of terminals with the other ohmmeter lead until you find the terminal that has continuity. That will be where you connect the grey wire and so on.

Let me know if you need further assistance.
