Thank you for the suggestions!!

it looks like I should bleed the brakes and then play with the wiring for the brake lights. By pass the switch by connecting the pink wire to the light green to see if the lights turn on, then pink to dark green to see if the suspension leveling works! If that happens than the switch is bad and it looks like I got a couple options to go with. fantastic thank you!

Looks like I will have to play with the turn signal switch and the head light switch to see if I can get those lights to function. The circular connector was connected when I inspected the underside of the dash. You mentioned the flasher could be incorrect, what would be the correct on? any part store one?

I did see the clips for the fuses were corroded so Ill have to address that as well.

as for the pictures you have Leeedy. Yes the fenders were off for painting. If you want current ones you will have to wait until I can get the car clean... Sitting for a couple years does create a lot of dirt. The top was not changed at all in the past 20 years (maybe more) or so. So if your pictures are within that time frame it is the same top


Okay.

Regarding the top on this Caribbean...one set of picx I have has no snap caps on the beltline connection of the top. Yet in other photos, there are indeed snap caps in the same position. Gotta be two different tops.

As for brake lights and turn signals... I've already talked about the brake light switch. In addition, always, always check to see that you have known good correct type bulbs with both filaments intact and working.

Turn signals and brake lights use the same filament of the two. Also some turn signals won't work with bogus aftermarket or modern replacement flasher units. Too many problems when mixing and matching and modifying and jerry-rigging make-do stuff. Once you start modifying things from factory, it becomes a very slippery slope and the dominoes can begin to fall. Too many complications can multiply just out of doing a presto-chango homegrown make-do. In the end you end of making more work and expense for yourself than if you just take the time to get the right original parts and follow the factory methods.

1956 Caribbeans differ from 1955 in that the electrical system for 1955 is positive ground and all the issues that entails. 1956 Has negative ground. As long as your tail light housings are firmly mounted in place and bulbs proper, sockets clean, wiring undamaged... and a proper, working brake light switch is installed your lights ought to be working.

Newer cars have built-in turn signal and brake trouble indicators that 95% of folks driving cars don't even realize exist (even when such stuff is mentioned in owner's manuals). Engineers build in things in cars that go completely unnoticed. For instance, some old cars will simply display a frozen "ON" illuminated indicator if a bulb in the run signal system has failed. Some Mopars in the 1970s would illuminate the interior light when stepping on the pedal if a brake light has burned out. For many years on most USA-made cars, if a turn signal bulb has failed, the blinker will flash at a quicker rate than normal. Most drivers are oblivious to this system.

And always remember that turn signals are not merely the tail lights but also the bulbs, wiring and grounding in the front turn signals/parking light housings. These factors must be taken into account.

Either way, in the end, you can never go wrong by sticking to the factory parts and specs.

So I did a little more digging into this vehicle over the weekend. I know Ross rebuilt the BTV and the individuals installed it and also fixed one brake line. But as I was looking into the reservoir it looked full but could not determine what fluid was in there. So I sucked it out (it looked a little dirty anyway) and bled the system with DOT 5. Well I got the car out of the garage and took it up the street, no more than a mile round trip. Accelerated and stopped fine. Kept the trans in low. I parked it when I got back to the house to move cars around. Before I moved it I checked the fluid and it was half empty... According to Ross the seals he uses are DOT 5 compatible so there has to be a leak somewhere... I did not see one initially so more work is needed there.

I did a little more diagnosing the brake light situation. I was able to confirm the switch was of the two prong type. Well peeling back the electrical tape it revealed that the color wires did not match what the service manual said. Pealing it back further did reveal the dark green and light green wires, but also a violet wire (it should have been pink). I was able to confirm that the green wires went to where they needed to go, but I was not getting power to the violet wire. I dont know how this happened but the 7.5 amp fuse that should be used on this circuit was actually tied into the shifting harness? Dont know why, there is no mention of a fuse there in the service manual. But I did notice a fuse wire not attached to the solenoids (which was red). Well it turns out the violet wire is connected to that red wire. I didnt put in a new switch but I did jump both light and dark green wires. The brake lights activated and I got the suspension to automatically level. Well not as good as the cars do in the youtube videos, but as good as it always did.

It is a purple wire on later harnesses but might have been pink in 55 and early 56. In 55 it was powered from a fuse under the dash along with a lot of other things but for 56 it got the separate 7 1/2 amp fuse and is attached to the solenoid power buss bar. It gets power fed thru the main 30 amp TL fuse first. There was a late bulletin about adding a fuse for the electric shift and that might be there but the fuse supplying TL & brake lites was never attached in any way to the shift circuitry.

For the brake switch, I would advise either getting a premade 2 terminal and relay setup or else building your own. The two green wires should not be together as they are supposed to be active at exactly opposite conditions. The way it is when together the level can operate when brakes are on and car might not be in a normal position. In actuality, it is supposed to be the light green is active at all normal driving so the level can operate. When you apply the brakes the dark green wire gets power for the brake lights and light green power goes away so the system does not try to level when the brakes are on and gravity might have thrown the car nose down.
