Can anybody tell me where the safety switch on a 1980 model 450 SL is located ?
From what I have read the safety switch is activated by the fuel pump relay when you open the air flow sense plate.
According to a troubleshooting test, I should check or replace that switch, and I'm not sure if its inside the fuel distributor housing or outside of it.
I also would like to know what function that safety switch is.

Thanks for the help.
