A first gen pickup and a first gen 4runner have a much different engine bay. First gen runners look like 2nd gen pickups It's all doable, just get EVERYTHING from whatever donor vehicle you chose-keep the harness as initially unbutchered as you can, make sure it runs before you start pulling stuff apart. After you weed out all the optional stuff on the harness, plug it back in and make sure it still runs. Have fun
