There are factory wiring diagrams for the 41 Clipper and all 42 models you can download from the literature section here. The factory diagrams have decent print quality but are harder to chase wires due to the prewar Packard style where wire continuity is determined by chasing a number rather than the actual lines as is done on the AEA schematics at the link O_D posted.

There is not going to be much available on interior lighting as almost all varied by model or was an option. Until the late 40s Packard generally placed lighting accessory or option schematics on separate pieces of paper which shipped with the item if it could be dealer installed. Those schematics were typically not included in overall diagrams. Apparently not many of those papers survived.

There is a question as to when or on what model Packard changed from placing the courtesy light switches in the power side vs the ground side. I suspect it may have been with the Clipper because some prewar conventional body schematics do show a single courtesy light with the switch in the power side whereas 41 and 42 Clipper schematics do not and just has the label "To body feed" coming off a fuse -- same as the postwars.. Postwar cars have the switches in the ground side so with that nomenclature I kind of suspect the prewar Clippers may too. One other clue would be if your switches have two terminals it is most likely in the power side. If the switches only have one wire terminal it is in the ground side.

One poster (don't remember who) was kind enough to supply an early front courtesy light sheet which I believe was for conventional bodies. It may have been used on Clippers but that is the big unknown. The diagram shows the courtesy light switch in the power side. I believe the 48 diagram was the first to show fairly complete interior lighting. In those are a front and rear light setup which I suspect but cannot prove may have been the same for prewar Clippers. Those 48 diagrams were identical to what was in postwar Clippers.

I have confirmed via direct observation that another 48 drawing of the limo courtesy lights was identical to the 21st series Clipper senior models although due to fading I couldn't verify the colors. If your car has lights on the rear of the front seat plus the two quarter courtesy lights over the rear seat it may work for your car. If not the single courtesy light may work. If none are appropriate and you have the two terminal switches, perhaps you can figure out where to place the switches to get yours to work.

Anyway, for what it is worth here are bits of the pre and postwar schematics I have. If anyone has known prewar interior info hopefully they will post. If you could confirm the type switches you have that may also be an indication of power or ground side switches in prewar Clippers.

Thanks for this, my pillar switch was broken, so depending on the switch are go to switch the live feed being - i am still running + ground. Are run the wires how i know i want them another job out of the way. On a different subject I collected my stainless steel sill foot plates, the reproduction rubber ones were just to much money. I plane to etch the worh packard onto the stainless.

Here is the factory wiring diagram from this site.

1941 Clipper wiring diagram

Thanks for That. Howard

Well I have got the new front fog lights fitted, and the siren and the blackout light. If any body can help I am need the panel the bolts down to cover the gap in front of the radiator. here is a pick of the front and the gap that is in front of the radiator.

There are different upper splasher panels for the various models. The small sixes have one which is shallow and shorter compared to those used on more senior models. I am not sure what the differences might be on those larger panels or for those cars with AC.

You may also be missing a support bar for the wiring crossing in front of the radiator. I am not 100 % sure where it was located on yours since I can't see the inner fender panels in your photo and there are some differences in pre and postwar panels. If you have nothing, I would suggest fabricating something so the wires are not caught in the airflow and subject to vibration.

Here is an example of the wire support that was used on a 21st series before I cleaned and repaired one end. It is an upside down U channel stamped out of sheetmetal with clips toward each end to hold the wiring. The ends of the U where it mounts to the panels are flattened and tapered to fit the angle of the inner fenders. One bolt on each end thru the inner splasher panels.

Hi Thanks for that, I cant remember one of those bars being there, but thats a very good point thats another thing to fabricate. A sunday morning job I think. Thanks Howard

Hi does any body body have a wiring diagram, i have a link for one but the writing is not very clear, i need a diagram of the complete layout. Also does any body know if its possible to refit the light and other switches once the dash is back in or should they be fitted back into the dash before the dash get bolted back into place. Thanks

Strongly recommend that you build and wire the dashboard complete before installing it in the car. That is how it was done on the assembly line. It will save you much time and keep your blood pressure at a manageable level.

Hello Ross, Thanks for that. Something i have spotted on the wiring is that the parking lights we call them side lights the fronts come from the light switch but the rears from the instrument light switch was there a reason for this. I was going to wire them to come on with the fronts. Any views welcome. Thanks Howard
