88 s4 na timing

Ok I didn't understand exactly where to hook up my timing light.

Besides the battery. My book says some where on the coils by the battery?

Could some one explain how?

You can connect your timing light to either wire of the leading coil. This is the coil closest to the battery.

The idle speed of the engine MUST be under 1000 RPM otherwise the ECU will advance the timing and screw up the reading. Time the engine to the yellow mark on the pulley by moving the CAS.

In general, the timing does not move unless the CAS has been moved or removed.

I'm not sure what you mean. Spark plug wire? The plug wires need to be connected from the coils to the engine to actaully start the engine, and in the right order.

Right I know that. Sorry to confuse you.

Ok I read a manual on how to time the car. Its telling me to hook up to a wire coming off the coil pack closet to the battery. And then jump a green pluged set of wires and check t-1 & l-1.

It confused the hell out of me.

I thought that you would hook up the negative and positive wires from the timing light to the battery then I thought that the other wire coming from the timing gun goes to clamp on the spark plug?

If you could just explain how and where to hook the timing light in detail for me. I understand what to do as far as adjuting to timing goes it just the part of hooking the darn thing up I'm confused on...
Sorry to sound like a jackass but this would be my first time doing this I just want to make sure I'm right before I'm go and adjust anything. Hopefully this might explain things better for you.

Connect the positive cable from the timing light to the positive cable of the battery. Connect the negative cable of the timing light to the negative of the battery or a good engine ground. The pickup then clamps to one of the leading plug wires (from the coil closest to the battery). "L1" is the wire you are supposed to use (front rotor, leading) but it really doesn't matter.

The green jumper would be the "initial set coupler" which forces the ECU to lock timing. But as long as you are under 1000 RPM, the ECU will keep timing at the yellow mark.
