Verify that the shift shaft in the Neutral position.
ImportantDO NOT ROTATE A NEW PNP SWITCH. A new PNP switch is pinned in the Neutral position. If the bolt holes do not align with the mounting boss on the transaxle, verify that the shaft is in the Neutral position.
Adjust the PNP switch if the new switch has been rotated and the pin is broken or if using an old PNP switch. Refer to Park/Neutral Position Switch Adjustment .
Align the flats of the shift shaft to the flats in the PNP switch.
Install the PNP switch to the mounting boss.
Caution! Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
Install the PNP switch mounting bolts.
Tighten the PNP switch mounting bolts to 25 N·m (18 lb ft).
Install the automatic transaxle range selector lever. Refer to Automatic Transmission Range Selector Cable Lever Replacement .
Install the automatic transaxle range selector cable.
ImportantVerify that the engine starts only in the Park position or the Neutral position once the PNP switch is installed. Readjust the PNP switch and/or check the shifter and the automatic transaxle range selector lever if the engine starts in any other position. Refer to Park/Neutral Position Switch Adjustment and/or Automatic Transmission Range Selector Lever Cable Adjustment .
Install the throttle body air inlet duct. Refer to Air Cleaner Assembly Replacement in Engine Controls.
Remove the blocks from the wheels.
Disengage the parking brake. Hope this helps, the page was read only so no pictures. Info is for 3.1L engine.

These vehicles are not equipped with a conventional neutral safety switch or back-up light switch. Instead, the automatic transaxle is equipped with a Transaxle Range Sensor (TRS), which is located on top of the valve body. This sensor performs the functions of the neutral safety and back-up light switches.
The TRS, if defective, must be removed with the transaxle's valve body as an assembly. The TRS is mounted on the top side of the valve body.

Your safety interlock switch is going out or is not adjusted properly. There is a procedure for adjusting the switch. The switch is on the transmission in the engine compartment. If you want to adjust the switch, loosen the botls holding the switch and follow steps 7-8 below. Else, you can just replace the switch entirely by following all steps.
The neutral start and backup switch are one unit mounted on the top left end of the transaxle. The neutral start portion of the switch allows electrical current to travel to the ignition system when the shift selector is in park or neutral only. The vehicle will not start when the selector is in any other gear. The backup portion operates the rear backup lamps when selector is in the reverse gear.
REMOVAL & INSTALLATION
See Figures 1 and 2
Make sure the shift selector in the Park position, then apply the emergency brake.
Disconnect the negative battery cable.
Disengage the neutral start switch electrical connector, then remove the shift control lever on top of the switch.
Remove the two neutral switch attaching bolts, then remove the switch.
no, this is one of those situations where you either have the parts to splice it back together or you need to replace the whole line. . Its a dealer part unless you can remove it and go to a autoparts house and match it up.

Neutral Safety Switch - REMOVAL & INSTALLATION
1985-89 Eldorado and Seville See Figure 1 The neutral
safety switch prevents the engine from being started in any transmission
position except Neutral or Park. The switch is located on the upper
side of the steering column under the instrument panel on column shift
cars, and inside the shift console on floor shift models.
Remove the console for access on floor shift models.
Disconnect the electrical connectors.
Remove the neutral switch.
Place 1967-70 column shift lever models in Drive, and 1971 and
later models in neutral. Locate the lever tang against the transmission
selector plate on column shift models.
Align the slot in the contact support with the hole in
the switch. Insert a
in. (2.38mm) diameter pin in place. The switch is now
aligned in Drive position.
1973 and later neutral safety switches have a shear-pin installed to
aid in proper switch alignment so that insertion of a pin is
unnecessary. Moving the shift lever from Neutral shears the pin.
Place the contact support drive slot over the drive tang. Install
the switch mounting screws.
Remove the aligning pin. Connect the electrical wiring, and
replace the console.
Set the parking brake and hold your foot on the service brake
pedal. Check to see that the engine will start only in Park or Neutral.
Fig. 1: Installation of a common neutral safety switch
See Figure 2 1974 and later cars do not have a neutral safety switch. Instead,
these cars have an interlock between the lock and the transmission
selector, which is non-adjustable.
Place the shift lever in Neutral.
Move the switch until you can insert a gauge pin,
in. (2.38mm) diameter, into the hole in the switch and
through to the alignment hole.
Loosen the switch securing screws. Remove the console first, if
Tighten the screws and remove the pin.
Step on the brake pedal and check to see that the engine will only
start in Neutral or Park.

1985-89 Eldorado and Seville See Figure 3
neutral safety/back-up light switches come with a small plastic alignment pin installed. Leave this pin in place.
Place the shifter assembly in the Neutral position.
Remove the shifter lever-to-switch nut and the lever.
Disconnect the electrical connector from the neutral
safety/back-up light switch.

Hope help with this (remember rated and comment this). Good luck.
Check 1 The Park/Neutral/Back-up light switch has a black colored insulator and is located at the lower left hand side of the transaxle near the oil pan. The switch inhibits starter motor engagement unless the gearshift lever is in the PARK or NEUTRAL position and completes the back-up light circuit when the gearshift lever is placed in REVERSE. 2 Prior to checking the switch, first make sure the shift cable is adjusted properly (see Section 4). 3 Raise the vehicle and support it securely on jackstands. Extract the 2 push-in fasteners and remove the transaxle splash shield. 4 Disconnect the electrical connector from the Park/Neutral/Back-up light switch. 5 Using an ohmmeter, check for continuity between the center terminal of the switch and the switch body. Continuity should only be present with the gearshift lever in PARK and NEUTRAL. If continuity is detected with the gearshift lever in any other position, replace the switch. 6 Next, check for continuity between the t wo outer terminals. Continuity should only exist with the gearshift lever in the Reverse position. Check the for continuity between each of the outer terminals and the switch body. No continuity should be present. Replace the switch if it fails any of these checks. 7 Install the transaxle splash shield and secure it with the 2 push-in fasteners. Lower the vehicle. Replacement Refer to illustration 6.10 8 Raise the vehicle and support it securely on jackstands. Extract the 2 push-in fasteners and remove the transaxle splash shield. 9 Working under the vehicle, disconnect the electrical connector from the switch. Place a drain container under the transaxle as some fluid loss will occur. 10 Unscrew the switch from the transaxle using a box-end wrench (see illustration). Discard the switch seal. 11 Look into the switch opening in the transaxle. Have an assistant shift the transaxle from PARK to NEUTRAL. Check that the internal operating fingers are centered in the switch opening. 12 Install the new switch and seal into the transaxle and tighten the switch to the torque li sted in this Chapter's Specification Section. 13 Recheck the switch operation (see Steps 1 through 6). 14 Attach the switch electrical connector, install the transaxle splash shield and lower the vehicle. 15 Check the transaxle fluid level and add more, if necessary (see Chapter 1).
The neutral safety switch is on the top of the automatic transaxle (under the hood). You have to remove the air cleaner assembly for access to this item. Once the air cleaner is off, you can see the switch mounted on top of the transaxle. Remove the shift linkage, electrical connectors and vacuum hose as needed. Remove fuel line bracket if needed. Remove mounting bolts and nuts to remove the old switch.
Install new switch as reverse of above. Put shift lever in neutral. Align switch so it's alignment hole and the matching tang hole line up. Tighten down the switch mounting bolts. Verify that the engine starts in PARK and NEUTRAL. Re-adjust if it doesn't. Charlie
