1997 Tahoe viper alarm 550 esp

I need to know what color of  wire or location of  the neutral safety switch???

Thanks for the info..  but what is a DMM??  Is this a digital multi meter or

something new????

Where is the tack wire besides on the coil?  Is it the same color and is it on the steering colum wirring harness on a 1997 Tahoe??

behind the cluster doesnt work until the new trucks, either 99 or 00+.  the ones ive pulled before that are all plugs that snap into the dash, you cant get to the harness.  the tach is white at the ECM, which is located on drivers side inner fender. Tach wire found in a black plug marked 'white'.

if you use anything but a DMM on the wrong circuit you can mess some stuff up.  an installer at my job before me toasted a $900 computer from a test light/logic probe.

i wouldnt worry about a neutral safety aswitch.  most vehicles wont start unless its in park anyway.  and who/how would you get out of the vehicle not in park.  i dont think you can take the keys out.
