Have 67 Ford Mustang GTA 289V8. How do spark plug no. layout on engine left side is 1-3-5-7 and right side of engine is 2-4-6-8. Would that be correct and what is firing order?

I\'m assuming you have the 3.8 engine,although i believe the firing order is the same on all there v6 sideways mounted front wheel drive Windstars. That firing order is 1-4-2-5-3-6, with 1-2-3 going from left to right on the back side of the engine and 4-5-6 left to right on the front side of the engine.Looking straight down at the coil from the front of the car,you\'ll see 2 rows of coil terminals.The row on the right side is 1-2-3 going from top to bottom,row on left side is 6-5-4 going from top to bottom. Hook the number 1 coil terminal to the number 1 spark plug ,being careful to use the spark plug wire that is closest in length to the length you need. If your just replacing wires,yuo shouldn\'t have to much trouble. If your nreplacing the spark plugs you will find the ones in the rear,especially the number 2 [the middle one} are pretty difficult without removing the cowling. A total pain brought to you by the designers at Ford!

number 1 is the front plug in an in-line engine the number 2 plug is next in line on a "v" engine the number 2 plug is on the other side of the block but its still called number 2 cylinder left or right side!

Sitting in the drivers seat, drivers side is the Left side, passenger side is the Right side.

From the Front of the engine going towards the rear,

Right side: 1, 2, 3, and 4

Left side: 5, 6, 7, and 8.


Front of the engine, RIGHT side coil pack. Two spark plug towers in Front.
Left side is Number 5. Right side is Number 1

Front of the engine, RIGHT side coil pack. Two spark plug towers in Rear.
Left side is Number 3. Right side is Number 6.

Front of the engine, LEFT side coil pack. Two spark plug towers in Front.
Left side is Number 8. Right side is Number 4.

Front of the engine, LEFT side coil pack. Two spark plug towers in Rear.
Left side is Number 2. Right side is Number 7.

its a distributorless ignition system so looking at engine left/passenger side is 1--2--3- drivers/right side is 4--5--6 the firing order is 1-4-2-5-3-6

Your firing order is 1-4-2-5-3-6

1-2-3 on the left, front to rear
4-5-6 on the right, front to rear

-KC GTO Dad

Firing order is 1-4-2-5-3-6 Cylinders are numbered as such: Standing in front of the car looking at the engine the cylinders farthest from you on the back side of the engine are from left to right, 1-2-3 and on the front side closest to you from left to right 4-5-6.

1.Vin B
2.Vin 3
3.Vin C
4.Vin 1
5.Vin L
6.Vin K

All have the Firing Order of 1-6-5-4-3-2

For Vin B and 3:
Hood open, looking at the engine from the front of the car. The coil pack is behind the engine, close to the firewall. (Under the windshield)
The crankshaft pulley is down on the left side.

Spark plug numbering, for the spark plugs close to the radiator side.
From Left; (Front of engine), going Right-> 1-3-5
Spark plug numbering, for spark plugs on the backside of the engine.
From Left going Right-> 2-4-6

The distributorless coil pack sits on the backside of the engine, close to the firewall.
Numbering of where to put the spark plug wires;
There are three spark plug towers close to the engine. From Left to Right -> 3-5-7
There are three spark plug towers far from the engine. From Left to Right-> 6-4-2

For Vin C, 1, L and K:

Hood open, facing the car.
The Front of the engine faces to the Right. The crankshaft pulley is down, and to the Right.

Spark plugs close to the radiator;
From Left to Right-> 6-4-2
Spark plugs close to firewall, (Below windshield)
From Left to Right-> 5-3-1

The distributorless coil pack sits on the right side, in front of the engine. (The Front of the engine is on the right side. The crankshaft pulley is on the Right side)

Starting at the ->Back and coming Forward. (To the Front of the car)
On the Left side of the Distributorless Coil Pack, it is -> 4-2-6
On the Right side it is -> 1-5-3

3.0L (2V) = 1-4-2-5-3-6

3.0L (4V) = 1-4-2-5-3-6

THESE TYPE CAN TRAP AIR DURING REFILLING, TRY REMOVE CAP ON PUMP, START ENGINE, SLOWLY TURN STEERING WHEEL, RIGHT - LEFT, CHECK FLUID FREQUENTLY WHILE DOING THIS, THIS SHOULD PURGE SYSTEM OF AIR .

you are correct right=5678,left=1234,as you are facing motor.also,if you need to know firing order,it is stamped on intake manifold near distributor
