Technical 1949 MerC Wiring

I have my 49 MErC in a restoration shop and I’m getting told the headliner will have to come down for wires to run through the roof line to the rear section of the car ! Does the rear window have to come out to do this ? Any suggestions to bypass doing that ? I’m thinking the dome light wiring can remain , change the bulb , bypass the rest and run the wiring through the floor pan under the carpet ! IDK ! Looking for suggestions Thanks

 

I would go with your idea of running new wiring under the carpet. Heck of a lot of unnecessary work otherwise.

 

100% under carpet. Especially if the headliner is original and in good shape. Messing it up could be a $2000+ problem getting it redone.

 

You can get flat 7 core insulated wire which lies nice and flat under the carpet from trailer supply places.

 

On my 50 the only wiring that ran through the headliner is the dome lt.

 

If you are chopping the top, run it under the headliner.

 

My 49 Buick has the tail light wiring run through the A pillar and over the door and rear side window. So the headliner would have to come out to rewire as stock. But with a good headliner I would run the wires under the carpet.
