Hello,

I am restoring 2 1933 Super 8 and bought 2 wiring harnesses. The first fitted great but now I am running into an issue with the second one. I suspect I may have a wrong switch (located at the bottom of the steering column) but I am not sure if I can use as is and just change the connections or if I need to locate another switch.

In the enclosed picture the drawing came with the wiring harness. The picture of the part is the one that I have that came with the car. Any help in identifying what I have would be great. Many thanks

According to source books of the era the correct switch for a 1933 Super 8 is an R.B.M. Co. Model LS-600.

Many thanks but I am puzzled as to where you have found the R.B.M. number? I checked the part book on page 168 and I get PN 209456 but do not see RBM.

I guess I will start inquiring around for model LS-600. Any idea as to what I have?

Thanks again

The publication Standard Auto-Electricians Manual identifies that R.B.M. unit as Packard's source for headlight switches used in 1933. The same switch was used in 1934 and a very clear wiring diagram for it is in the 1934 Service Letters which are available on this site. Also, general wiring diagrams both on this site and on The Packard Club site show the switch, though by far the one in the Service Letters is the clearest.

Super8, here's the illustration fron the 1934 Service Letter.
