I've lost the wiring diagram

"I bypassed the immobilizer circuit only on my alarm module (which is really tedious). Bypassing the whole
module is possible (and little easier), but you will lose the use of the remotes and the ability to arm the alarm.
The alarm module in my '97 900 SETC is located under the carpet, below the driver's power seat switches (a
pain to get at).
If you want to bypass the module completely:
1. Disconnect the battery (make sure you know the radio code-if needed)
2. Unplug the connector from alarm module and remove module from car
3. Install a wire jumper between pin 8 and pin 20 in the connector
4. Install a wire jumper between pin 9 and pin 21 in the connector
5. Install a wire jumper between pin 10 and pin 22 in the connector
6. Wrap securely with electrical tape
If you want to bypass the immobilizer circuit only:
1. Disconnect the battery (make sure you know the radio code-if needed)
2. Unplug the connector from the alarm module
3. Cut the following wires from the back of the connector and splice together as follows (Don't cut the wires too
close to the connector, because someday down the road you may want install a new module, so you'll have to
reverse this process):
4. Cut the wires to pin 8 and pin 20 and splice together w/ wire nut
5. Cut the wires to pin 9 and pin 21 and splice together w/ wire nut
6. Cut the wires to pin 10 and pin 22 and splice together w/ wire nut
7. Secure all with electrical tape
8. Reconnect the connector to the module
Not knowing the details of your problem, please be aware that this may, or may not, solve it. Good luck and let
me know how you make out."

We do not have any wiring diagrams. Contact the manufacturer or a local Buick repair shop. Thanks

I just spotted this, hence the late solution. Perhaps this will help someone in the future.

Yes it is possible.

Observe the color code of the insulation of the wires.

1) Orange wires are 3.3 Volts

2) Red wires are 5 Volts

3) Yellow wires are 12 Volts

4) The Green wire is the Soft Power On wire

5) All Black wires are Ground wires. Doesn't matter which Black wire it is, it's a Ground wire.
(It isn't a Common wire. This is DC electricity, not AC)

These are your main voltages, and wires to be concerned with.

Fortunately all HP, (Or any proprietary computer manufacturer in that time period), did, was to change where the wires are placed in the 20, or 24-pin ATX main power cable connector.

They just moved the wires in the socket holes, didn't change the color code.

Solution is,
1) To remove the wires in the ATX power supply, main power cable connector
2) To remove the wires in the proprietary computer's ATX main power cable connector.

(NOTE*
BE SURE to make a concise, clear, drawing FIRST, of where the colors of the wires went in the proprietary connector, BEFORE you remove them!)

3) To reinstall the wires into the proprietary connector.
(Again. Following the color code of the wires you removed)

Removing the wires out of the 20, or 24-pin ATX main power cable connector:

Observe these photos, of a 20-pin ATX main power cable's connector. This procedure can be applied to a 24-pin ATX main power cable connector also. (Or a 20 + 4-pin ATX main power cable connector)

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20

(Also gives you information about the color code of the wires)

The middle photo shows you a view of the Front of the connector.
The photo to the right shows you the Back of the connector.

Where the wires go down into the connector is a Socket Hole.
At the end of each wire is a metal pin connector. A Male pin connector.

This metal pin connector is shaped like a tube on the end, and comes up to a square shape as you go up.
The square shape fits the square socket hole.

On one side of the square shape is a Tang. It's part of the square metal shape, and sticks out away from the square shape.
Resembles a barb on a fish hook.

In this crude illustration, let a small L represent the side of the square shape, and this forward slash - / represent the tang.

This is an illustration from a manufacturer that supplies this type of metal Male pin connector,

http://www.molex.com/molex/products/datasheet.jsp?part=active/0002092166_CRIMP_TERMINALS.xml&channel=Products&Lang=en-US

A needle with the proper thickness so it won't bend, is inserted into the Front side of the socket hole, and is used to depress the Tang.

If you look down into the back of the connector, and into an individual socket hole with a bright light, and a magnifying glass, you will observe that the square socket hole has a small notch in one side.
This is where the tang slides down into.

It isn't easy to see from the front side.

The tang is depressed using the needle from the FRONT of the ATX main power cable connector, and the wire is removed from the Back side of the connector.

The metal pin connector's tube shape only goes up so far, then it turns into a square shape.

The socket hole in the connector is shaped to match. Tube shaped hole at the front of the connector, square shape coming on up to the back of the connector.

The square shape's corners, of the metal pin connector, keep it from coming out of the Front of the ATX main power cable connector.

The tang keeps the metal pin connector from coming out of the Back.

Hi bossman9628A, normally its the wire colors that messes everyone up when trying to connect the front case wires to the motherboard. The MSI RX480 Neo2-F, AKA MS-7151 MB is no different but does use a second set of pins just to help you get more confused.
Gather up all your case wires. You'll notice there is one color that is common. Chances are that color is white & is being used for the ground wire. Other colors like blue, green, red, light blue, light green & light red ECT are used for positive. The speaker uses black for ground/negative.
So looking at JFP1 at pin 1 is positive +. Pin 3, which is to the right of pin 1 is negative -.
The manual does show you which pin is negative & which is positive. Pin 1 = (HD_LED_P). The _P stands for positive.
Pin 3 = (HD_LED_N). The _N stands for negative. Do not connect the Power led at JFP2. Keep the power led connected at JFP1.
Do connect the case speaker at JFP2. Most cases do use 2-pin connectors but others use 3 & 4 pin connectors. If your case is such you can remove a wire from a connector by using a decent needle. There is a small black tab that you can pull towards your self while pulling the wire out. You can than slide the wire back into the connector where you need it. You'll know the wire is inserted correctly because you'll hear or feel it snap into the connector. If by sme chance you get a led backwards, don't freak out. The leds use 5v DC. Just shut down the system & turn that led 180deg & reconnect it.

Good luck bossman9628A!
