I just dumped the codes on my car and got a code 67. Now, I looked it up and found it pertaining to the Nuetral Safety

I found this by jricher

jrichker said:
Code 67 - clutch not depressed (5 speed) or car not in neutral or park (auto) or A/C in On position when codes where dumped. Possible neutral safety switch or wiring problem. This code may prevent you from running the Key On Engine On tests. You can generally ignore this code, since it has no effect on engine performance.

The computer wants to make sure the A/C is off due to the added load on the engine for the engine running tests. It also checks to see that the transmission is in Neutral and the clutch depressed (T5, T56, Tremec 3550 & TKO)). This prevents the car from being driven while the computer is in test mode. Key On Engine Running test mode takes the throttle control away from the driver for several tests. This could prove hazardous if the computer was jumpered into test mode and then driven.

Now, my car is a converted 5-spd, but I'm still running the AOD computer and wiring. The NSS on top of the T-5 is not hooked up, but I don't think this is that because the AOD comp shouldn't be looking for it since it was not present on the AOD tranny

I changed the clutch wiring around so that it's 5-spd correct and the once-jumpered wires are now plugged into the clutch safety. SO, how does the above pertain to 5-spd cars? When the codes are read, must the clutch pedal be depressed the entire time.

I used a digital code reader, so i was outside the car. But i want to verify this code 67 goes away. Car runs fine and won't start without clutch pressed in..so not worried but i want to see it disappear. How do i need to perform the test with a 5-spd? When do i press the clutch in?

That should be a soft code in which it wont trigger a check engine light, that code will always be there, due to the fact the AOD computer looks for a NSS everytime the key cycles.
