SOURCE: firing order for a 1986 gmc s15
To avoid confusion, ALWAYS replace spark plug wires one at a time.
The most important thing to remember about the removal and installation of a distributor, cap or spark plug cable is that all wires MUST be labelled before they are disconnected. Keep in mind that these figures depict a firing order where the distributor cap terminals are relative to EACH OTHER only and they do not necessarily depict the tower positions in relation to the rest of the engine. This is true because any distributor which has been removed and reinstalled may have been installed with the No. 1 spark plug tower at any position (360 degrees) in relation to the rest of the motor, as long as the rotor aligned to the No. 1 tower when the No. 1 cylinder was at TDC of the compression stroke (valves closed, ready for the plug to fire). As long as the remaining wires were connected in the correct firing order sequence (depending on direction of distributor rotation) the engine will run. DO NOT EVER remove more than one wire from the distributor cap at a time unless you tag ALL wires and towers to assure proper installation.
Fig. 1: 1.9L engine . Firing order: 1-3-4-2 . Distributor rotation: counterclockwise
Fig. 2: 2.0L engine . Firing order: 1-3-4-2 . Distributor rotation: clockwise
Fig. 3: 2.5L engine . Firing order: 1-3-4-2 . Distributor rotation: clockwise
Fig. 4: 2.8L engine . Firing order: 1-2-3-4-5-6 . Distributor rotation: clockwise
Fig. 5: 4.3L engine. Firing order: 1-6-5-4-3-2 . Distributor rotation: clockwise
I hope help you with this (remember rated this help) Good luck.

SOURCE: i need a wiring diagram
I don't have the wiring diagram, but here is how it is wired, the large red lead bolts to the insulated stud on the back of the alternator, the other 2 smaller wires are to the "D" connector, go to a good parts store like NAPA or CAR QUEST and ask for a repair connector for your alternator, it will be a stub connector with 2 wires in it, just splice it to the old wires and plug it in, one wire is bigger than the other so it's hard to screw that up. Any further questions just post a new message. Go to it and lets drive!
