94 3100 wire harness. I have a white and brown wire into a red plug loose where does it go?

I own a 94 Buick century custom 3100 v6 and it was not running right so I took to the guy we bought it from and asked to find out what was wrong. Mostly because he had a bunch parts from other cars that would fit and I won't have to buy all the stuff. He didn't fix it and we have being buying pieces and adding them. But we found the wire loose under the coil pack. It's red plug end with brown and a white wire going into it. We were wondering if that could be why it runs good two times and then on the third time it misses and stalls. We have changed the wires and plugs and cam sensor and trans axle sensor and crank sensor on it. Any help is welcomed Thanks

Only one brown/white wire in the diagram I found, but I wouldn't expect that wire to be near the ignition system or to have any effect on it.

    The diagram shows two crank sensors. Is there one in the distributor? I think that is the one that runs to the ignition module. Distributors I see online have two cables. Are there two cables coming from your distributor? The wire colors are wrong, but sure sounds like crank position issue.

    We know that one and it is connected. That's behind the power steering pump and that wire will not reach there. The wire that connects to that comes across from the front of the engine.

    And the other crank sensors are at the vibration damper?

    I checked several years of diagrams, and the wire colors are consistent. There are no two-wire connectors with brown and white. If those are the colors, it is likely someone has replaced some of the harness. That connector looks like it fits on the cylindrical crank sensor that slips into the block. The other sensor slips under the vibration damper. It is shaped in an arc and has a three-wire connector.

2001 Buick Century installation help for receiving harness. I am attempting to install a connection so I can tow with my Car however, I cannot find any information about this installation anywhere.


Your wire colors are roughly the same as for a standard 4 wire trailer. Dark green is right turn, yellow is left turn. You have brown with white stripe for park lamps--connect this to the brown trailer wire. The white or black trailer wire connects to the car body or frame. Ok?

The clock stays on in my 1996 buick century v6 and the radio fuse in glove box does not effect it, i tried removing it and had clock still on , is there a secondary fuse for clock?


Look for a "3" Amp fuse on the Fuse Block as it will be singularly used for just the Clock and should be clearly marked "Clock." The Clock should have a Red wire running out of it to the Fuse Block to power it. The Clock is typically wired separately. The red wiring will not be in front as it goes into the wiring harness and in the back of the Fuse Block but if you want to hunt for the Clock wire that will be it running out of a segment of the harness heading for the location of your Clock.

Es lexus 300 p 1705...What is this?


DTC P1705 - NC2 (Direct Clutch Speed Sensor) Revolution Sensor Circuit malfunction or Direct Clutch Speed Sensor Output is 300 RPM or less with Vehicle at 20 MPH or more & with Park/Neutral Position Switch Off

Most probably you have an electrical fault causing the problem and attached is a diagnostic procedure. It could be 2 separate problems and after rectifying the P1705 only would you know it is single or 2. Repair manual shows right on top of transmission, black sensor with single bolt, 2 wire plug. P/N 89413-08020 list price $113.80

NOTE: DTC P1705 is set when PCM receives 2 gear position signals at the same time.

1. Turn ignition on. If any A/T gear position indicator lights remain illuminated when gear selector is moved from that gear, go to next step. If all A/T gear position indicator lights turn off when gear selector is moved from that gear, system is okay at this time.

2. Disconnect A/T gear position switch connector. If all A/T gear position switch indicators go out, replace A/T gear position switch. If all A/T gear position switch indicators do not go out, go to next step.

3. Reconnect A/T gear position switch connector. Shift through all gear positions except Reverse. Using a DVOM, measure voltage between 16-pin PCM harness connector "D", terminal No. 6 (Green/Red wire on 2.3CL or White wire on Accord and Odyssey) and 25-pin PCM harness connector "B" terminals No. 20 or 22 (Brown/Black wires).

If battery voltage is present, go to next step. If battery voltage is not present, check for a short in Green/Red or White wire between 16-pin PCM harness connector "D" and A/T gear position indicator, or A/T gear position switch. Repair as necessary. If Green/Red or White wire is okay, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary.

4. Shift through all gear positions except Neutral and Park. Measure voltage between 16-pin PCM harness connector "D", terminal No. 13 (Blue/White wire on Accord or Light Green wire on 2.3CL and Odyssey) and 25-pin PCM harness connector "B" terminals No. 20 or 22 (Brown/Black wires). If battery voltage is present, go to next step. If battery voltage is not present, check for a short in Blue/White or Light Green wire between 16-pin PCM harness connector "D" and A/T gear position indicator, or A/T gear position switch. Repair as necessary. If Blue/White or Light Green wire is okay, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary.

5. Shift through all gear positions except "D4". Measure voltage between 16-pin PCM harness connector "D", terminal No. 9 (Light Green/Black wire on 2.3CL or Yellow wire on Accord and Odyssey) and 25-pin PCM harness connector "B" terminals No. 20 or 22 (Brown/Black wires). If battery voltage is present, go to next step. If battery voltage is not present, check for a short in Light Green/Black or Yellow wire between 16-pin PCM harness connector "D" and A/T gear position switch. Repair as necessary. If Light Green/Black or Yellow wire is okay, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary.

6. Shift through all gear positions except "D3". Measure voltage between 16-pin PCM harness connector "D", terminal No. 8 (Green/Blue wire on 2.3CL or Pink wire on Accord and Odyssey) and 25-pin PCM harness connector "B" terminals No. 20 or 22 (Brown/Black wires). If battery voltage is present, go to next step. If battery voltage is not present, check for a short in Green/Blue or Pink wire between 16-pin PCM harness connector "D" and A/T gear position indicator, or A/T gear position switch. Repair as necessary. If Green/Blue or Pink wire is okay, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary.

7. Shift through all gear positions except "2". Measure voltage between 16-pin PCM harness connector "D", terminal No. 14 (Green/Yellow wire on 2.3CL or Blue wire on Accord and Odyssey) and 25-pin PCM harness connector "B" terminals No. 20 or 22 (Brown/Black wires). If battery voltage is present, go to next step. If battery voltage is not present, check for a short in Green/Yellow or Blue wire between 16-pin PCM harness connector "D" and A/T gear position indicator, or A/T gear position switch. Repair as necessary. If Green/Yellow or Blue wire is okay, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary.

8. Shift through all gear positions except "1". Measure voltage between 16-pin PCM harness connector "D", terminal No. 15 (Light Green/White wire on 2.3CL or Brown wire on Accord and Odyssey) and 25-pin PCM harness connector "B" terminals No. 20 or 22 (Brown/Black wires). If battery voltage is present, check for loose PCM harness connectors. Replace PCM with a known- good unit if necessary. If battery voltage is not present, check for a short in Light Green/White or Brown wire between 16-pin PCM harness connector "D" and A/T gear position indicator, or A/T gear position switch. Repair as necessary. If Light Green/White or Brown wire is okay, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary.


Hope helps.
