SOURCE: Need diagram for 1998 Jeep
hi, you didn't say what engine you have, I'll assume it's the 4.0 L in line 6 cylinder. Standing on the PASSENGER side of the jeep, the spark plug at the front of the engine is #1, the next is #2, and so on to #6 which is at the back (nearest the windshield).
The distributor is between you and the valve cover on the engine. Pretend the top of the distributor cap is the face of a clock.
The #1 spark plug wire goes in the cap at what would be the 6 o'clock position, (as viewed from your position standing on the passenger side, facing the side of the engine). The firing order direction is clockwise, so the 'hand' of the clock (actually the rotor in the cap) would continue to the next distributor cap plug in, which would be spark plug wire to #5 (8 o'clock position), then #3 (10 o'clock position), #6 (12 o'clock position), #2 (2 o'clock position), #4 (4 o'clock position). So all this means isi your firing order is, 1,5,3,6,2,4 If you have a different motor or any questions, let me know. Good Luck! countrycurt0

Number 1 plug is in the front, with 2,3,4,5, and 6, right after it, going towards the back.
The distributor rotates Clockwise. Viewing the distributor cap from the top, view the two mounting screws. One on the lower right, the other is on the upper left.
Number 1 spark plug tower, is immediately to the ->left of the lower right screw.

If you intend to keep the vehicle long term, I would suggest you invest in a Haynes Manual, That is worth its weight in gold, for this and any other project..

ALL Jeep 4.0 motors use this firing order. Any year, any model, high output or not.
Also, the spark plug wire placement on the cap, in a clockwise direction from the post nearest the engine block is: 6-2-4-1-5-3.(to the left side of the number 6 post, there should be a hold downscrew or strap for fastening the distributor cap to the distributor.
