The purple wire with a white stripe goes to the starter from the neutral safety switch. I believe it is the yellow wire at the neutral safety switch that will have the the signal from the ignition switch for the start signal. ( Test this yellow wire with a test light while holding the key in the start position to see if it lights to make sure yellow is the correct color ) and join the wires together. This will by-pass the neutral safety switch

you may need to adjust to the right position.

Test/Service/Replace Neutral Safety Switch
Most neutral safety switches are combinations of a neutral safety switch and a backup lamp switch. Others have separate units for these two distinct functions. When the reverse light switch is not part of the neutral safety switch, it seldom needs adjustment, as it is directly activated by the transmission or the gear selector linkage.
Typical location of a neutral safety switch on a transaxle. Reprinted with permission of Ford Motor Company. A neutral safety switch allows current to pass from the starter switch to the starter when the lever is placed in the P or N position. Some neutral safety switches are nonadjustable. If these prevent starting in the P or N position and the gear selector linkage is correctly adjusted, they should be replaced.
To adjust a typical neutral safety switch:

• Place the shift lever in neutral.
• Loosen the attaching bolts for the switch.
• Using the angling pin, move the switch until the pin falls into the hole in its rotor.
• Tighten the attaching bolts.
• Recheck the switch for continuity. If no voltage is present, replace the switch.
• The switch sometimes controls the operation of the back-up lights also. With the engine off and the key on, put the selector in reverse position. Check the back-up lights to see that they are on. Then, check in the drive position to see that they are out.

I have the same problem few days ago, and still didn't find any solution. Can any one please help?????18

P0705 - Transmission Range Sensor Malfunction. The park/neutral position (PNP) switch includes a transmission range switch. The transmission range switch detects the selector lever position when the shift lever is in the N or P shift position and sends a signal to the Transmission Control Module (TCM). The possible causes of this are the following: Open or short park/neutral position switch circuit. Poor park/neutral position switch circuit connection. Misadjusted park/neutral position switch. Park/neutral position switch may be faulty. Inspect the pnp switch and replace if needed.

OBD Code P1750 = Solenoid Assembly / Manufacturer Control Transmission.

I tell you it is infact your solenoid box assemble is going. What that does is to tell your transmission when to shift into gears. Im assuming your car is having a hard time shifting gears and juts need replace this part.


OBD Code P0705 = Transmission Range Sensor circuit (PRNDL - Input).

I'll check the Neutral Safety Switch. It's located on the shift shaft of the trans, and is a common problem. Also check the wiring leading to the switch, as it is exposed to road grime and has been known to corrode and melt.

Also can review this DTC P0705.

Hope helps.

most gm nuet safety is yellow and purple .....out of ignition switch is a big yellow wire that is crank out and input to nuet saf switch......out of nuet switch is color purple that goes strieght to start selenoid.....purple wire also goes to the crank fuse 5amp.. in the fuse box under dash... this fuse goes to the pcm main computer.. same for auto and clutch
