I think " Hoppe" makes a wiring kit that will plug right in, if you can't find that you may have to tap or splice into the wiring. Green-right turn/stop. Yellow-left turn/stop Brown- tail lights. White- ground. I hope this helps. Take care.

SOURCE: 1991 Buick Park Avenue- computer problem?

You can find it under the passenger side, below the glove box. Usually, when they fell, you will get mutiply codes that don't make sense, but needs to be tested with a scan tool, Genesis, or Snap on Scanner.

Need a picture of firing order on a 1991 Buick Park Avenue

Check this site I believe the black images is the coil pack firing order. I used a coil pack from a different model but had to open it up and change the firing order since the spark wires wouldn't reach for my 91 buick. You should have some knowledge about wiring before attempting that. Basically I just switched the wiring on each side inside the coil pack.https://www.google.com/search?q=buick+1991+park+avenue+firing+order&tbm=isch&tbo=u&source=univ&sa=X&ei=reisU9eSH9HioAThh4D4BQ&ved=0CC8QsAQ&biw=1440&bih=748

No power to trailer plug on toyota fj fuses are good

if you mean a 4 pronged plug at the rear of your vehicle that allows you to plug in and tow a trailer safely and legally , then get yourself a testlight and check each prong for power. 1 leftturn, 2-rightturn, 3-parking lights 4-ground .if you have no power at plug check condition of wiring connections at plug and follow harness to source. if you have power at plug the problem is in the trailer. check groundwire, wiring,and bulbs.

Where is the computer connction on a 1991 buick park avenue?

Do you mean the ALDL connector or the harness for the computer?
If you mean the ALDL connector for the scanner, it's on the left side under the dash.
If you mean the harness for the computer, it's under the glove compartment where the computer is connected to the harness.

Good luck on reading those codes.

Buick park avenue engine start problem

Try replacing the coolant control temp sensor, the one to the computer (usually it will have two wires), not the sensor to the temp light or gauge (usually has only one wire).

1991 Buick Park Avenue Ultra dies while driving. replaced crank sensor, coil pack wiring harness. oil pressure guage flies back & forth

It is most likely a sensor. It is common in these. You may check them with an ohmmeter.
You may also test relays the same way.

A vehicle needs gas and spark to run. One of them is not getting to motor. You can check fuel pressure on test port on fuel rail for fuel.
You can pull off a spark plug, plug it back into wire, lay it on top of motor, have someone else crank, while you watch for spark, Put back in, move to next plug wire.

Trailer hitch...no running lights (2004)

You'll have to follow the BROWN wire from the factory connector(with the running lights on of course) to the trailer connector and make sure you are getting power all the way to the two lamp fixtures. If so you've probably got two burned out 1157 bulbs or an inline fuse in the factory harness/ trailer harness.Good Luck, Dana
