i had that van before lol ( blew the tranny hahahah ) use a multimeter to find your 12v and your acc when key is on. then ( i also had the same prob as you ) there should be 4 sets of different color. dont remember the exact color but for ex. orange with brown line goes with the orange with blue line.

anyway when you have all the power hooked up power the deck and put fader to only 1 speaker than hook up the matches and try them on all 4 sets of speakers

eventually you will get it ( took me 2hours lmao) ill check if i can find a diagram online for ya
