I do not know what the original problem was , but you may need a wiring diagram for the car.

If the car is a classic Pontiac grand Prix you can find wiring diagram here.

If it is a modern Pontiac, you can find diagrams here: 1990 Pontiac Grand Prix 3.1L Wiring Diagram

Let me know the year of the car, and give more details on the problem.

regards.

COIL PACK WIRING DIAGRAM


The coil pack wiring is relatively straightforward though the exact wiring, colours and suchlike will vary a little from car to car.

A 4 cylinder engine will have a coilpack containing four individual ignition coils - one for each cylinder, but they are likely to be wired as if there is only two. This is to simplify the wiring and to cut a little unnecessary complication from the ECU.
Effectively those four coils are two pairs of coils - the primary windings of coils one and four are wired in series and similarly the primary windings of coils two and three.

When cylinder number one fires a spark is also generated by coil number four but causes no effect as that cylinder is at the top of the exhause stroke. This is called the wasted spark principle.

The same effect can be obtained by using a single coil per two cylinders of a type which has a single secondary winding which is completely isolated or not grounded in any way. One end feeds one spark plug and the other end is also terminated in a spark plug wire and terminal.

This simplification means the coil pack (4 cylinder example) is fed by only three or four wires (usually four).

I hope this helps.

How to install aftermarket radio in 2009 mazda 6


The smartest thing is spend the money and purchase vechial adapter pigtail made specially for your brand of head unit and presided connector for a easy plug and play, from crutchfield.com. No guess work no schematics or wiring diagrams to follow plug in connector to vehicle harness and back of your aftermarket stereo put the couple plastic pieces of trim and your done. The support side of crutchfield.com is a very good resource. But if you don\'t want to spend the cash for pigtail, you can create account on auto zone.com and go to vehical repair guides and click locations. Why electrical schematics are in the tab labeled, locations, is beyond me. Print it and it will give you the speaker color codes and wire functions with connect pin location numbers. Just remember the industry standard, except for couple exotics, is that first color listed is the main color separated by a /, forward slash, and followed by the color of the strips. And japain cars occasionally use a stopped lines. Same color codes as if solid stripe. Auto zone also has the manufactures service procedure of how to properly remove old stereo unit with out damage. If your car is too new for auto zone listing then I suggest pay $20 to alldatadiy.com as a mechanic the shop pays $1500 a year subscription for alldatapro.com which has all the manufacture procedures, tsb\'s, schematis, and locations, but for twenty a year per vehicle you have access to all the same information as the mechanic in all non dealership associated shops.

When doing wiring always use soldering iron, pencil snapped, not a wiring gun. Gun gets too hot unless your building battery cables. Walmart got one for something like eleven bucks. And use double walled heatshring for 16-22gauge wire. Double wall has heat activated glue that makes water tight seal.any corrosion from water corrosion will be noticed as distortion or noise in stereo system. Are you installing amplifiers or subwoofers? For the pound chest felt thump? Are you using factory speakers? What wattage are speakers? And measure resistance with digital multimeter or use speaker impedence Value. Head units only produce up to a 4 volt constant variable frequency and current to transmit signal. The 50watts x 4 channel is not 50watts per speaker its true my 50 watts peak and 1/2of peak watts of RMS WATTS AT 25. AND DEVIDED BY FOUR SPEAKERS IS TRUELY SOMETHING LIKE 6.5WATTS OR SO. NO IM NOT GRABBING CALCULATOR, 6*4=24 SO A FUZZ OVER. I HAVE FOUR SIX BY NINES RUNNING OFF A 4 CHANNEL 600 WATT RMS 1200 WATT PEAK DUAL MONOBLOCK AMP RUNNING AT 4 OHMS PER SPEAKER WIRED IN PARALLELD EQUALS 2 OHMS OHMS PER BLOCK AND TOTAL OF 4 OHM TOTAL CIRCT LOAD OHM WITH ALL FOUR SPEAKERS USING BOTH BLOCKS. THE 600 WATTS IS RMS OR HALF OF PEAK AND WHILE USING DUAL MOMOBLOCK MEANS ONLY 300 WATTS PER EVERY 2 CHANNELS AT 2 OHMS. BUT IM WIRED AT FOUR OHMS AND OHMS LAW SAYS TO DOUBLE IMPEADANCE OR MEASURED CIRCUT RESISTANCE YOU NEED TO DEVIDE WATTS. SO 150 WATTS PER BLOCK. AND DEVIDE FOR TWO SPEAKERS AND GET 75 WATTS. SPEAKERS ARE RATED AT 90 WATTS, THANKS TO NEWEST 6X8 INCH, YA 8, 4WAY FULL RANGE SPEAKER. 4 WAY MEANS HAS FOUR SPEAKERS BUILT INTO ONE TO PRODUCE FOUR DIFFERECT FREQUENCY RANGES. STAY AWAY FROM COMPONET TYPE SPEAKERS AS YOU,LL HAVE TO MATCH IMPEDENCES, AND WIRE THE THREE OR FOUR SPEAKERS TOGETHER TO MAKE THE ONE FULL RANGE SPEAKER WITH CAPACITORS. AND ... ON AND ON. SO IF USING OEM OR ORIGIONAL MANUFACTIOR EQUIPTMENT, SPEAKERS YOU SHOULD NEED TO KNOW IF THEY ARE COMPONET OR FULL RANGE. AND NEWER CARS HAVE THE AMPLIFIER AND ALL THIS MATH MATCHED TO PROPER RATED SPEAKERS. AAN WELL AS A CFEW YEAR OLD VEHICAL MAY HAVE A 1200 DOLLOR KENWOOD IN IT WITH BUILT IN AMPLIFIERS THAT AFTERMARKET SYSTEMS DO NOT HAVE. BUT NO TAG SAYS THAT. IT\'LL SAY DELPHI FOR CHEVY MOPAR FOR CRYSTLER , MOTORCRAFT FOR FORD, AND SO ON. SO. HOW FAR DEEP DO YOU WANT TO DIVE? THE MONEY SPENT ON CONNECTOR ADPTING HARNESS FROM CRUTCHFIELD MAY HAVE JUST PAID FOR ITS SELF. IN STRESS AND ****** OFF TIME SPENT. AND THEY HAVE GOOD PRICES ON HEAD UNITS, SPEAKERS, DASH ADAPTER KIT, FOR PLASTIC SIZE AND MOUNTS FOR THE DIFFERENT SHAPED UNIT, AND GIVES A DISCOUNT IF YOU BUY THE UNIT AND ADAPTER HARNESS TOGETHER. WITH FREE SHIPPING A LOT OF THE TIME WITH AMAZING SUPPORT PAGE, CRUTCHFIELD IS THE PLACE TO GO FOR MOBILE AUDIO.

How do i remove a carbine alarm from my 1994 mazda miata mx 5


if this alarm was fitted after the car was made then these wires will make connection's to the vehicle's wiring 'you wont find a matching connection, just trace the path of these wires and i expect you will find that where they connect it will be where ONE wire has been cut and each end connected to the alarms wiring ie to cut the power to the injection/fuel pump to stop vehicle being started,one of these connectors will be for power supply and earth so check with voltmeter first then trace and dissconnect, a bit of patiance and all will be good keep me posted if you wish

What size engine does a 2000 Pontiac Grand am have and does it have spark plugs?


It will either have a four cylinder 2.4 liter or a 6 cylinder 3.4 liter.

The 2.4 liter will have four plugs located under the cover on top of the engine. The cover can be removed by removing the four bolts with a 13mm socket, unplugging the connector on the drivers side, and lifting up.

The 3.4 liter will have three plugs on the fron and three plugs on the back. You can follow the plug wires from the coil to the spark plugs. Remove the wires from the plugs and remove/install.

How do you replace the turn signal relay


Hello jaglx007: My name is Roger and I will help. By relay I assume you mean the turn signal flasher. To locate the flasher you will need to remove the panel under the drivers side dash. This requires a 7 mm. socket and a nut driver.Remove the row of screws in the bottom cover. The ones in the bottom of the dash. Should be three or four. Look at the fuse box. At the rear of the box you will find the flasher. Will be held to the rear of the fuse box by a metal clip. The flasher will be round in shape. Un clip the flasher and disconnect the wire harness. Reverse the procedure to put the car back together. Should you need further help please just ask. Please rate the answer you received. Thank You for using Fix Ya. Roger

I have a problem with my pcm on a 96 monte carlo. every three or four days the control module fails to power up and the car wont start for a couple of days. is it a power problem or a module problem? what...


There was a problem in the 96 luminas with the Ignition relay in the under hood fuse box.
I would try trading the Ignition relay with a matching relay in the fuse box and see if the problem goes away, make sure you mark the old ignition relay so you can find it later. If the problem stops, purchase a new relay and replace the old one.
Below is a schematic of your under hood fuse block.
Good luck, let me know.

Wire harness for trailer


You will need a test light, don't worry about the colors. Four wires, one for left turn signal, one for right turn signal, one for parking lights, and one is ground(usually black). Hook up ground, turn on trucks left signal and hookup to one of trailers other three wires, you will either light up the correct light or wrong one just continue til lights match coming off your truck to what you want to light up. And brake lights are left and right signal, so if you do signals the brake light will work. I can explain further if you need help.
