Where do plug wires go on distributor - 1990 Buick Regal

1. Connect the distributor's B+ (battery) terminal to a switched 12-volt source, such as the ignition switch.

2. Connect the distributor's tach terminal to the tachometer signal wire, if you have a tachometer.

3. Connect the distributor's ground wire to a good engine ground.

4. Connect the distributor's #1 spark plug wire to the #1 spark plug on the engine. The #1 spark plug is usually located on the driver's side front cylinder.

5. Connect the remaining spark plug wires in firing order sequence to the distributor cap terminals. The firing order for a Buick 455 engine is 1-8-4-3-6-5-7-2.

6. Install the distributor cap and rotor.

check coil wire--distributor /dist cap

If you look at the distributor cap from the wires side carefully, you would find either a line mark on one of the outer side of four holes (where the spark plug wires are inserted) or the numbers printed on the top of distributor cap (1,3,4,2). Fix one end of the longest high tension plug wire into number 1 hole or the one marked with a line mark on the distributor cap and the other end on spark plug number 1 (the number 1 plug is toward the pulleys and the belts side, then No 2, No 3 and No 4). While standing in front of right wheel you will see the distributor cap in front of you. The rotor moves clock wise. After you fix the 1st cord, next comes number 3 plug wire. Insert one end of the cord into the next to 1 on the right hand side and press the other side of the cord on spark plug number 3. Next to 3 is the cord number 4 and the last one is number 2.

Installation of wires

1. Whenever a high tension wire is removed for any reason from a spark plug, coil or distributor cap, or a new high tension wire is installed, Silicone Dielectric Compound WA-10, D7AZ-19A331-A (ESE-M1C171-A) or equivalent must be applied to boot before it is reconnected. Using a small clean tool, coat entire interior surface of boot with Silicone Dielectric Compound WA-10, D7AZ-19A331-A (ESE-M1C171-A) or equivalent.

1. Insert each wire on proper terminal of distributor cap. Ensure wires are all the way down over their terminals. The No. 1 terminal is identified on cap. Install wires starting with No. 1 terminal.

1. Remove wire retaining brackets from old high tension wire set and install them on new set in same relative position. Install wires in brackets on valve rocker arm covers.

1. Connect wires to proper spark plugs.

1. Install coil wire.

Installation of distributor
Before installing distributor, visually inspect distributor. Inspect O-ring. It should fit tightly and be free of cuts. The drive gear should be free of nicks, cracks and excessive wear. Rotate distributor drive shaft. It should move freely, without binding.

1. To install distributor correctly, No. 1 piston must be at Top Dead Center (TDC) of compression stroke. Remove No. 1 cylinder spark plug and rotate engine clockwise until No. 1 piston is on the compression stroke.

1. With No. 1 piston on compression stroke, align timing pointer with TDC on the crankshaft damper.

1. Align locating boss on rotor with hole on armature. Fully seat rotor on distributor shaft.

1. Rotate distributor shaft so blade on rotor is pointing toward mark on distributor base, that was previously made in Step 2 of the Removal procedure.

1. While installing distributor, continue rotating rotor slightly so leading edge of the vane is centered in vane switch stator assembly.

1. Rotate distributor in block to align leading edge of vane and vane switch stator assembly. Verify rotor is pointing at No. 1 mark on distributor base. If vane and vane switch stator cannot be aligned by rotating distributor in cylinder block, remove distributor enough to just disengage distributor gear from camshaft gear. Rotate rotor enough to engage distributor gear on another tooth of camshaft gear. Repeat Step 1 if necessary.
   

1. Install distributor hold-down clamp and bolt. Tighten bolt, but leave it loose enough to rotate distributor.

1. Install distributor cap, No. 1 spark plug and ignition wires. Check that ignition wires are securely connected to the cap and spark plugs. Tighten distributor cap hold-down screws to 2.0-2.6 Nm (18-23 lb-in).

1. Reconnect distributor to wiring harness.

1. Set initial timing according to procedures found in Section 13A of the Powertrain Control/Emissions Diagnosis Manual .

1. After timing is set, tighten distributor hold-down bolts to 23-34 Nm (17-25 lb-ft).

1. Recheck initial timing. Adjust if necessary.

change one spark wire at a time on the distributor.buy new set of spark plugs wires remove them from box.match old wires with new wires to use the correct length to each cylinder.now if you need to change distributor cap.mark location distributor cap.number tag plug wires on the distributor cap so you can remove plug wires on distributor cap so you can replace cap and rotor and put wires back on the distributor cap in correct place.remember change one plug wire at a time so you wont get confuse.

TAG OR NUMBER ALL SPARK PLUG WIRES ON THE DISTRIBUTOR CAP BEFORE REMOVING CAP. SO YOU CAN PUT PLUGS WIRES BACK IN THE ORIGINAL POSITION. WHEN ALL PLUGS WIRES ON DISTRIBUTOR CAP BEEN NUMBER.REMOVE ALL PLUG WIRES ON CAP.THEN REMOVE THE DISTRIBUTOR CAP.THEN MARK ROTOR POSITION WITH SHARPIE MARKER THEN REMOVE THE ROTOR.

1 PLUG WIRE ON DISTRIBUTOR WOULD BE AT 12 OCLOCK POSITION.1 CYLINDER IS FIRST FRONT CYLINDER ON DRIVER SIDE.

check the gaps on plugs also distributor also condensor in distributor

You are correct in your idea about how the plug wires are attached. If you want to duplicate control wiring you would need to obtain the wiring diagram of the brand of ignition system you want to duplicate. (MSD etc. These systems also require a small battery in order for them to operate. Wiring to distributor was far less complex when vertex type magneto distributors sere used as all that was required was a ground wire to shut them down (exactly like your lawnmower works), As far as plumbing, all systems need to meet safety standards set forth by the NHRA but aside from meeting those standards, each engine builder decides where to locate such items as primary and secondary fuel injectors etc. If you go to the NHRA website, you may be able to find a decent photo of someones engine...that may be helpful. Also check the rule book for such items as kill switch location, brake, chute release etc.
