How can I tell what plug wire go where on the distributor cap? Diagram shows #1 but I can not really tell if it is on the left of coil wires or not.


Is this the diagram you are looking at? #1 terminal is behind the screw, right? Does your distributor have the 4 screws? Sorry if I'm not understanding the question.

To avoid confusion, remove and tag the spark plug wires one at a time, for replacement.
If a distributor is not keyed for installation with only one orientation, it could have been removed previously and rewired. The resultant wiring would hold the correct firing order, but could change the relative placement of the plug towers in relation to the engine. For this reason it is imperative that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations. If the current wiring does not match, make notes in your book to reflect how your engine is wired.

1990 deville distributor


With a car that year, the only replaceable item is the rotor button. The cap itself is also replaceable. If the gear itself gets damaged, you have to replace the whole thing.
