I changed the distributor cap and had forgotten which way the spark plug wires go for An Audi 80/ 1990/1.86 engine. Theres 5 inputs I've got the center one correct but not sure of the other 4!!

Here's information on your car
if it's a four cylinder it's 1-3-4-2
if it's a five cylinder it's 1-2-4-5-3
cylinder one is nearest the radiator up front
last cyclinder is always near firewall (Rear)
