Muncie TCS switch question
Ok boys and girls, Ive got a trick question...
So Ive done a little research on this little fitting [that I broke] wich sits in the side cover of my M21, directly beneath the 3/4 shaft hole.
So this thingamijig is called a "TCS" switch and in some way shape or form controls the spark advance....for some reason my research indicates that it allows vacuum advance when the car is in 4th gear. That is unless I have completely misinterpreted something and would gladly accept education in this matter.
My question is, rather than spend $32 on a new part that may possibly be detrimental to the performance of my car, should I just plug this hole with another fitting, or is there some advantage to running the correct switch in accordance with 1974 emissions standards?
As always, thanks for your input....gettin closer to puttin this puppy back on the road!
