4-cyl. or V-6?
Either way you'll want to pull off the distributor cap and then manually crank the engine until the timing mark is at TDC. AT this point the rotor should be pointing at cyl. #1.....plug in the wire for cyl. #1 to the corresponding terminal on the distributor cap. The V-6's firing order is 1-2-3-4-5-6, so just go clockwise from wherever #1 is. The 4-cyl's firing order is 1-3-4-2 (I believe), so hook them up accordingly.
Here's a diagram of where each cylinder is (the @ is the distributor)
V-6:
6 4 2

5 3 1
4-cyl.:
4 3 2 1

I hope this helps.
