Need a spark plug wiring diagram for a 1988 ford f 150 inline 6 cylinder?

I'm going to guess that you need the spark plug wiring diagram. I hope that's what you want. I am also guess that you have the 6 cylinder because the 8 cylinder didn't have a coil pack but the coils were on the spark plugs. I hope this is what you're looking for and I hope this helps. Good luck.

OKAY STANDING IN FRONT OF ENGINE ON LEFT SIDE CYLINDERS FACING YOU IS 1 3 5 ON RIGHT SIDE DRIVER SIDE CYLINDERS FACING YOU IS 2 4 6 LOOKING AT DISTRIBUTOR CAP NUMBER 1 SPARK PLUG ON CAP IN THE 9 OCLOCK POSITION YOUR NUMBER 5 SPARK PLUG ON DISTRIBUTOR CAP IN 6 OCLOCK POSITION .STARTING AT NUMBER 1 SPARK PLUG ON CAP COUNTING CLOCKWISE COUNTING 1 2 3 4 5 6 THATS YOUR SPARK PLUGS WIRES ON CAP TO ENGINE PLUGS. 6 PLUG WIRE ON CAP IS AT 7 OCLOCK POSITION.

Depends on your engine, Inline 6 (1-5-3-6-2-4) 302 and 460 (1-5-4-2-6-3-7-8) 351 (1-3-7-2-6-5-4-8)

FIRING ORDERS NOTE: 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.

The COIL PACK TOWERS are numbered : coil----3---4 pack---2---6 plug----1---5 ----------------------------------------------------------------- The engine cylinders / spark plugs are numbered : passenger side , front to rear , 1 , 2 , 3 -----drivers side , front to rear , 4 , 5 , 6 ------------------------------------------------------------------- The spark plug firing order is ( 1 -4 - 2 - 5 - 3 - 6 )

Easyer to explain then it is to get a diagram. Standing facing your truck cylinders are numbered 1 to 6. The front most cylinder being one and the back one closest to the cab is 6. The blackened terminal on the distributor cap indicates the number one spark plug wire position. In clockwise order from the blackened terminal firing order is 1-5-3-6-2-4.

need to fix lock

you didn't say if you have the straight 6 or v 6.But i'll give the order for both.
The 4.9L straight 6 is 1-5-3-6-2-4----------- distributor rotor turning clockwise, and #1 plug is the first plug.
On the 3.0 and 4.2 V6 engines is 1-4-2-5-3-6-------#1 plug is the first plug on driver side---- facing engine.

ho the throttle position sensor will cause the truck to surge.
