What is the firing order for a 1998 Toyota tacoma 4 cylinder

Most 4 cylinder engines use 1, 3, 4, 2 as a standard firing order. Number 1 cylinder is positioned nearest the belts and pulleys, and cylinder 4 is nearest the transmission. The coil packs are often marked with the numbers 1 to 4 to show which cylinder they are meant to go to.

Firing Order 1-3-4-2

The firing order of in-line 4 cylinder engines is the same (for old car models) of Chevy, Olds, Pontiac, Dodge/Plymouth, Datsun/Nissan, Honda, International, Isuzu/LUV, Jeep, Mazda/Courier, Mitsubishi, Opel, Toyota and VW.
"Always check the exact firing order of your engine. It is is generally stamped or cast on the engine's intake manifold, valve cover or cylinder head."

firing order is 1,3,4,2.

2TR-FE 2.7 is 1-3-4-2
1GR-FE 4.0 is 1-2-3-4-5-6
Cylinder #1 is front on the 2.7, front passenger side on 4.0.
On the 4.0, passenger side bank is 1-3-5, driver side is 2-4-6 (front to back).

Coil pack connection is physical: Coil 1 to Cylinder 1, 2->2, etc.

I am not sure if this is your question, but firing order matches spark to TDC (top dead center) on the power stroke. The design of the crankshaft determines this.

1-3-4-2 is common for most straight 4's. Cylinder 1 is closest to the crank pulley. I believe your coils are 'waste spark' which means it will fire two cylinders at the same time. When the coil fires, one cylinder is on the power stroke and is wanting this spark. The other cylinder is on the exhaust stroke at this time, and thus the spark is 'wasted' on that cylinder. But a cylinder with exhaust gas has high impedance, so most of the energy is delivered to the intended cylinder.

If your question was 'should I just connect 1->1, 2->2, 3->3, 4->4' [ yes!] vs. ' should I try to connect coils following the firing order' [no] then the answer is the first. The trigger wheel determines which coilpack fires when, you just need to hook up the wires number for number.

The firing order is 1-3-4-2

Number one is the one at the pulley end of the motor and number 4 is at the flywheel end of the motor.

System uses a Distributorless Ignition System (DIS) with 2 ignition coils. Cylinders No. 1 and 4 use the same ignition coil. Cylinders No. 2 and 3 use the same ignition coil.

For the 2002 Toyota Tacoma:
I do not know if you have the 2.4L, 2.7L or the 3.4L; however I have included all three below.

For the 2.4L AND 2.7L:
Firing Order:
1-3-4-2
Cylinders:
(back)
...4
...3
...2
...1
(front)
Ignition Connections:
