Re: Back up lights on 56 Crown Vic

If there is no power, as you say, "in or out" I would look for a problem from the source of power to the switch. You can also do a quick check to see if the wiring from the switch to the lights is functional by jumping power directly to the wire at the switch. Disconnect the wire that goes to the lights and jump to that. I would make a jumper that utilizes an in-line fuse for the test. You could also use that jumper to connect to the power in side of the switch to verify if the switch works and to check the nadjustment of the switch. |

If the NSS really isn't getting any power the starter solenoid and starter shouldn't function either. Because the car starts you'd think that's all working fine, except... if the car can start in gear the NSS is bad, out of adjustment or a previous owner bypassed it with a connection directly from the Ign switch to the starter solenoid. (like a certain red car in my garage) . Last edited by dmsfrr; 03-13-2018 at 07:13 PM. |

Re: Back up lights on 56 Crown Vic
Back up lights were optional.my 55 never came with with them from the factory and are wired to the light switch and only come on when the lights are on. I am thinking about hooking them up to the accessory side of the ignition switch.

Re: Back up lights on 56 Crown Vic
Most vehicles have the reverse lights wired for operation without the light switch involvement. If you think about it, it makes perfect sense. This is how you can tell someone is going to reverse the car if you are approaching it from the rear. Even during the day, this is an important caution for other drivers to note in case the reversing car can not see the other cars approaching it.
Wiring to a load side of a buss circuit breaker will protect the circuit wiring on an automatic transmission application since the car is generally always left in park. Manual transmission cars with overdrive are a different matter though since they should be shifted into reverse when parked on a hill due to the overrunning clutch. In this case, they should be wired to the ignition switch "on" circuit with an in line fuse. Some of the old ignition switches are kind of limited on how many wires can be installed on the accessory terminal but it can generally be made to work.

Re: Back up lights on 56 Crown Vic
As I understand all of this...
The 56 FORD BU Lamp was an option (BIRD $8.50). I a$$-u-me it was factory assembly if a customer new car order or the dealer specified them on a stock order. Quote:
There were also kits made available for dealer and/or customer install. The kits can still be found on EvilBay and this would include everything to upgrade the car to factory assembly. I have also noticed harnesses and other service parts on the Usual Suspect Online stores. The 1956 FORD ELECTRICAL MANUAL (available reprint) would give all the details.

I also have a '55 Car (and Thunderbird) Shop Manual and backup lights aren't mentioned in it at all. Last edited by dmsfrr; 03-21-2018 at 03:02 PM. |

Re: Back up lights on 56 Crown Vic
It still kills me off how they show a very good illustration of the layout for installation but they don't have a simple wiring diagram. It's pretty much how Ford did things in the early years though.

The ELECTRICAL MANUAL you have dmsfrr... Is it FORD and BIRD or just BIRD? Is it Genuine FORD or a copy/reprint? That CHASSIS PARTS MANUAL is invaluable as it will have all the parts info for the years listed as opposed to the MPC which was edited as PN's were deleted from the system. There should also be available a BODY CATALOG to go along with it. You show the ILL for the rear harness. Under Basic No. 14405 TEXT it shows the harness containing the BU lamp wires (and turn signal wires) as included in that harness, if factory equipped or not. In that instance, installing the kit should be fairly easy. Now here is another quandary. One post shows the neutral safety switch (FM) as being replaced by a 57 PN (B7AZ 7A247-A). This switch should allow START in PARK and automatic illumination of the backup lamps.

Actual wiring diagrams come in the ELECTRICAL MANUAL. As it became more complicated, VACUUM and EMISSION MANUALS were released.

Re: Back up lights on 56 Crown Vic
My understanding is that the start in Park came with the 58 model year. TBirds I know did not have the start in Park in 1957.

THANX for catching this... There was a thread that showed vendors were selling the 57 FORD switch as a replacement for the BIRD. That can't be as the FORD did not have an AUTO floor shift. Either I need to find that thread or oldmics is going to pull my coat buttons off and break my sword...

Re: Back up lights on 56 Crown Vic
Here is what tripped me up. The thread is discussing FORD, not BIRD.
One of the maladies of getting old is diminished reading comprehension... Quote:

Re: Back up lights on 56 Crown Vic
There is a NSS that was used on Ford pickups that allows starting in Neutral & Park.
I have one & if I can find the number I will post it. Here it is: 1960-1966 Ford Truck This is a Ford number: C1TF-7A247-A I think I paid $35.00 for it Looks exactly like the original. Jim Last edited by Kahuna; 03-24-2018 at 02:52 PM. Reason: Added info |
