Wiring and Windows for a 56 CDV
« on: September 26, 2019, 12:51:56 AM »
Well the brake issue has been rectified thanks to you guys and my car has come back with a rebuilt front end, all new shocks and an alignment along with a carburettor issue finally rectified and it is awesome to drive, I'm thrilled.

One thing that has never been done properly is the wiring. I'm all for circuit breakers and fuses and I also want to get a new harness...Ö.. it has power everything as well. What advice can you guys give for that.... Painless Wiring and do it myself or is there someone over there who specialises in harnesses for these.

Also, My electric window switches are a bit dodgy. The plastic block behind the  drivers door switch (four switches) is quite rough and every now and then the window won't work. Are these available reproduction as I can't seem to find them anywhere.

Still lovin it!!

Several places reproduce the window switches. I got mine from Fusick automotive. They are near me in Connecticut so I was able to visit their showroom.

So I'm guessing that no one out there is known for making a wiring harness for 50's Cadillacs?

Bruce,

Not sure how handy are you in tackling the wiring yourself. It will be a tedious job in laying the hardness and weaving a new one and removing the connectors.  :(

You can always re-use the hair pin connectors at the switch blocks, you will need to solder them instead of crimping once they are removed from the old hardness.

Wiring color code maybe an issue depending on where you get the supplies specially the three ones with the tracers.  :(

By doing the work yourself you can up the wire gauge especially the main +12V feed. The ones pre-made would have a similar wire gauge as the original one. The original Delco motors will draw roughly between 10-12A under normal load and they could reach close to 25A under torque, so the original 14AWG power feed would be border line at best.

If your plastic insulator for the switches are crack/broken you can always epoxy-glue them back, the back plate can also be made. I have made a mold for both the main and the small insulators just in case.

One note you will surprise the main issue with the electric windows in most often the switches themselves, as I stated above there is a high current going across them and after 60 years the contacts start the fail, getting them back working is a 50/50. 

Iíll be adding relay packs to all motor windows (one of this days as I have to remove the door panels) to off-load the switch, hate to play with the switches while getting the windows up or down.

Good luck..!

Yes, very tedious.  I did it on my convertible.  It took longer to locate all the correct color and gauge or wiring but still  about 4 months work in building it.
It was worth the effort.  NO wiring issues on startup.
Good luck

I did it that way on my 54. I removed the original harness, laid it out on an 8x4 sheet of cardboard and cable tied it to the hardboard at various points. I then slit the insulation and that gave me access to the full layout of the harness. I had no problem getting the tracer wires here in the UK but had to get a few of the colours and some of the connectors from the USA. Phil
