Do you mean you need the firing order for the cap?

The firing order is "18436572" and should be on the intake manifold. On the intake manifold the clyinders will be numbered on or next to each intake runner. The cap only rotates one way, all you need to do is find at least where one of the plugs go on the cap.

The top of the intake manifold should have the firing order stamped on it. For instance the chevy is 18436572 ...not sure what it is for your olds.

What your going to need to do is remove the #1 sparkplug and bump the engine around with someone holding their thumb over the spark plug hole. Bump the motor around until the air just starts passing the persons thumb...that should be close to top dead center of the #1 cylinder.

Now you open up the distributor cap and where ever the rotor is pointing is the start of the firing order and that is where you start with the #1 spark plug wire. Now noting the firing order, you continue around the distributor cap placing the next wire on the cap that corresponds to the firing order.

Now on the Chevy motors the rotor turns in a clockwise direction but if I recall my nephews 70 Olds his turned counter clockwise.

oh boy

so it goes counter clockwise not clockwise on an olds?--ok so I have no idea where the first one starts--there are no wires on the cap right now--I see where the numbers are on the intake manifold but as far as the cap i have no idea where to start

i srewed up and posted this twice i think--but what does bump the engine around mean? Does that mean crank it with a key?

Go to the number 1 cylinder, take out the spark plug, turn the motor over by hand until you feel air coming out( please make sure that it is on the compression stroke and sure your not feeling the exhaust stroke).

Go to the cap, take the cap off, note where te rotor is and turn the motor to see which way the rotor on the distributor turns, this next contact in the cap would be number 1, it's all down hill from there.

If you dont know which way the motor would turn, look at the fan, turn the motor in the direction that the fan would pull air. Turn the motor by the lower pulley.

We can not do this for you, we can only tell you what to do.

EDIT: Do NOT turn the motor by key, use a breaker bar, or socket wrench with a socket that fits the balancer bolt to turn the motor, I think it was 1 1/4 socket, but cant remember.
