Hideaway Lights Motor Hookup?

[DynoDave]

Ok, I'll post 'em up. Gives me something to do while I listen to the Lions game. Here we go! #DriveBurnout#

I'm going to post 2 sets of drawing. The first will be the 1972 Factory Service Manual (FSM) pages for the Concealed Headlamp section, and the wiring information from elsewhere in the manual.

The second set of photos is from the '77 FSMs. By '77, they had added some basic diagnostic flow charts, and a different (I believe much more user friendly) wiring schematic layout. While these '77 full size C-body schematics will be worthless to you as far as specific circuit numbers / wiring colors go, it will probably give you a much better, more "traceable" schematic to follow.

Don't forget...this site automatically "shrinks" the photos. If they are too small for you to read, you can click on them to see them full size.

1972 Charger Engine Compartment Schematic, Page 1. Yikes! The whole engine compartment on a single page. I hate diagrams like this. I much prefer the '77 style, posted later.



1977 Concealed Headlamps Diagnostics, Page 1. Note the design of the hardware here (picture at top of page). You'll see a lot of very familiar looking components Vs. '72.



1977 Concealed Headlamp Schematic, Page 1. This is where it begins in the '77 style schematic. Again, I consider this layout to be much more useful. At the headlamp switch, it begins with circuit L2 16LGN. Are you familiar with the naming convention here? L2 is the circuit number. 16 LGN tells you this is a 16 gauge wire, Light Green.



1977 Concealed Headlamp Schematic, Page 2. This style drawing flows across the pages. Follow the circuit number across. This is where the lions share of the motor and circuit info. are. Thank to my son James for holding the page flat!



1977 Concealed Headlamp Schematic, Page 3. At the tail end of one circuit on the prev. page it said "see p.7-9", so here they are. It also said see pages 20 something....I included page 24 (Dodge) but not the other 2 (Chrysler), as they all looked the same.

Hope some of that helps out. Enjoy! #A_Toast#

wow thank you so very very much this is gonna help alot! atleast now i have a first step toward seeing the correct hookup for my hideaways! You have been a great help. Now i just have to locate the circuitbreaker and relay then i can begin the hookup or attemt to anyways. Thank you DynoDave.

You're welcome Charger1974SE.

These cars are from a time when you can actually still enjoy doing electrical work. Todays cars, not as much, IMO.

Since you are putting a '72 Grill in a '74 I "assume" you are not too particular about originality. If thats' the case, those relays/brekars are fairly interchangeable between all the cars that have concealed headlamps. The one for Chargers does have it's own shape of mounting bracket, but functionally it's identical to the others, IIRC.

Board member Tom often has these for sale. You might touch base with him.
