Swapped the weber on and now all kinds of issues. The truck is a G63b(Jan 1989). Been al over the truck looking for random wires that had no home. I came up with nothing. I have replaced the starter wire thinking maybe it had a bad spot in it. Looked at all grounds and found nothing. I am out of ideas. The only thing that doesn't have a home is the big connector that was connected to the old carb, and one more that had a ground on it. I grounded the wire and found one under the truck that was suppose to be grounded to the transmission. I took care of it and I am still popping ignition fuses. When swapping carb is there anything that needs to be done with the harness at all. Before I swapped carbs i could crank the truck with no problem. I am out of ideas. Please someone point me in the right direction!!!!!!!!!!!!!!!!!!!
