Looking for pin diagram for 98 double deck radio

[dreddog47]

I need to find out if the stock radio out of my brothers explorer actually works or not, he traded the truck in a month ago so i cant plug it in to the explorer, i tried with my marauder but the plugs are obviously and completely different, i was thinking i could just wire it up manually (just basic power to see if it turns on)

the guy he sold it to on ebay said the display didnt work, although it worked fine when we sold it, got it back and it sat in the box in the closet for 2 years.

can anyone atleast tell me what pins are for the Pos and Neg so i can wire it up to my marauder and see if the display turns on?

Thanks in advance

I found this diagram, but i cant exactly figure out which pin 1 would be, i assume the first pin, but i dont want to guess and blow a radio out.
