On the 69 RS headlight switches , when you pull it on does it switch the vacuum mechanically or by means of electric over mechanical function ?
I.E.; Can I check out a 69 RS headlight switch by simply applying vacuum (which does nothing as I test it now) , or do you have to have the switch plugged in and powered up to switch the vacuum on and off ?
The vacuum RS switch for 68 & 69 is mechanical. There is 2-port vac fitting on the switch. The fitting is sealed by internal rubber boot contained within a small metal slide. The slide has a lug bent at 90ļ to engage the switch slide mechanism. This lug can break off leaving the system inop.
Someone did a slide repro. They are easily removed. If you have a factory gauge car the h/l switch is different so don't discard it.
I may be able to help you out...
I have an original RS w/gauges switch that has a broken case. Everthing works on it...but it won't stay together.
Let us know what you find...
