What order are spark plug wires on the distributor for 1966 ford 289?

The firing order for a 1966 Ford 289 is 1-5-4-2-6-3-7-8.

However, the distributor cap wire placement will be the *reverse* of the firing order because the distributor rotates. Therefore, you'll need to look at your distributor cap from the top (looking down at the rotor) and the wires will be placed in the following order, corresponding to the distributor cap terminals numbered clockwise:

* 1 - Cylinder 1

* 5 - Cylinder 5

* 4 - Cylinder 4

* 2 - Cylinder 2

* 6 - Cylinder 6

* 3 - Cylinder 3

* 7 - Cylinder 7

* 8 - Cylinder 8

Important Note: Always double-check your specific distributor cap and engine for any markings that might indicate a different arrangement. Some caps might have numbers directly on them. If in doubt, consult a reputable Ford repair manual specific to your 1966 289.
