Re: thermo-time switch location on 8V

["Chris DeLong" <green536@hotmail.com>]

My mistake I thought for some reason that you had a 16V. Now that you 
mention exactly what the switch is you are correct. You must have an 8V. 
Your statement in the beginning is exactly correct. This switch turns on the 
computer and O2 sensor system. You should notice some major improvements in 
driveability when the car is warm. Don't forget to check your timing and 
fuel mixture as soon as possible 'cause not having this connected is going 
to change the duty cycle parameters of the frequncy valve. Set the timing to 
the exact mark and set the mixture. Then when all is set you can advance 
(mark towards the front of the car with respect to the pointer) a few 
degrees for more performance. Flywheel turns to the front of thee car. If 
you are looking at it from the drivers fender it is turning 
counterclockwise. HTH
