    Replacing the rear liftgate on my 04 V6 sr5 with that of an unknown year V8 Limited, due to rust and power window issues etc.
    The V8 Limited that I am attempting to put on has a spoiler on that back while my 04 V6 sr5 does not.
    I noticed that the wiring harness is not the same as my 04 V6 sr5 wiring splits into 2 with the second wire plugging into a black box under the headliner, I can unplug this but I am sure that box does something. The V8 Limited does not have this split in the wiring but does have it's own split in the wiring to power the light in the spoiler.

    The pins going into the connector are also in different spots and not the same amount. First pic is of my 04 V6 sr5 connector with the split in it. Second pic is of the V8 Limited connector without split.

    My V6 sr5 has 4 pins top left, 5 pins middle and 1 pin each side on bottom.
    The V8 Limited has 3 pins top right, 5 pins middle and 1 pin bottom left.
    Anyone know where I can find wiring diagrams for these?
    What can I do to get the new one on and working.IMG_20240702_130301531_HDR.jpg IMG_20240702_130352185.jpg
    Thanks for any and all help.
