I dropped this into the s-10 forum too, but need help soon. I installed a crate motor in this '89 S-10 Blazer in exchange for a paint job on my K5. The old motor blew up and this is supposed to be a little surprise for his wife when she gets backs from outta town because its her s-10. I can't time the damn thing! What wire do I disconnect. The sticker is gone and I'm timing this thing like a big TBI blazer. It has no guts and runs hot when I drive it. I unplugged a single wire connector over by the brake booster and timed it to 0 degrees. I plug it back in and it runs as smooth as could be, but no power. It can hardly pull a hill in 1st gear. I look later and the wire I unplugged was black with a white stripe. Isn't it supposed to be brown with a white stripe? There is a two wire connector next to it that has brown wires, one with a white and the other with a red stripe. Do I unplug this? Thanks alot.
