I have a Matco tools tachometer and I need to know what to set the DIP switches at.It has 6 DIP switches 1 and 4 are on and the rest of the switches are off currently(I bought it used from a guy that had it on a mustang).So I need to know what to set the different DIP switches at for however many cylinders the car has.I looked everywhere and cant find so much as a picture of this tach.Heres a picture I took of it:

Anyone know?
