355 Ferrari 355 Spider Top Roof Mechanism ALL Common Issues & FIXES

It's raining out so I spent some time to clarify the subject....

H-2 has two wires coming from it.
One is black the other Purple / Black

I do not get a BRAKE light on start up.

Where does the wire go from Pin 7?

 

On gated cars at least, pin 7 goes to the brake fluid level and brake pad wear sensors (and illuminates the brake warning light). There is also a module which illuminates the light on startup. P/N 61830700 on USA cars. All these wires for these sensors, etc, are spliced together. On gated cars, there is a separate PARK light on the dash (which sits where the Slippery Road Mode light is on the F1).

I don't understand why your pin 7 is missing. If you have your binnacle sitting on your work bench, try to see which pins your BRAKE warning light is attached to. i.e. the 2nd light on the bottom row. It should be attached to the Green/white wire (your pin 6) and one other pin/wire.

Thank you, but I think you've taken a photo of plug "I"

Plug H is the blue one.

It's a pity you didn't take that photo at a different angle, I can almost see H-2. I was looking for a white/red wire to confirm that the wire went to the fog light annunciator on the dash. On some other cars it is orange.

Actually, those wires on I-2 are horn-related. The purple/black wire comes from the horn buttons. The black/yellow(?) wire comes from the Immobiliser ECU. In some markets, the immobiliser triggers both the siren and the horn.

Facepalm. Sorry about that. I'll take it back apart and get the right wire later.

 

I have the 61830700 module on my car (1998 F1). What wire should go from what pin on the module to Pin 7?

Should be the pink wire on pin 8 (the pin by itself).


Ferrari have done their best to save money on the switchover from 2.7 to 5.2 and to F1. The instrument panel internal wiring seems to be the same (with regards to the warning lights). All that has been changed are the annunciator light bezels. If you had a wire or pin on pin 7, it should be attached to the BRAKE light.

Have you looked further back up the harness to see if there are any pink wires hanging in the breeze with, perhaps, a broken pin on it?

I kind guessed that as I was testing the pins and lights today.....

My car had a previous owner that did some odd ball stuff so who knows what he did with the wiring (he had it all apart and pretty messed up).

So if I ran a wire from pin 8 of the 61830700 module to Pin #7 on the 13 wire connector, would that get me a BRAKE light with the hand brake engaged?

 

I'll go look. Solid pink?

 

Affirmative.

 

OK. Stand by...while you eat breakfast, I have to go out to dinner with the Mrs.

 

No, but you should get the brake warning light on startup and brake warning lights when your brakes are broken. To get a parking brake light, you need to splice one of those orange/black wires into the pink wire/s.

 

Thanks for the reminder I do get rather involved sometimes with these things and forget to eat.

Something to consider. If you fix the BRAKE warning system, you may find you have faults on the brakes you didn't know you had before

Also, if you splice the park brake wiring into the brake warning wiring, if your brake warning lights come on due to brake wear or low fluid, you will be able to operate the roof at any vehicle speed. I think the probability of you doing that is pretty low and can always stop this happening by putting a diode in the circuit.

I can't believe the F1 car doesn't have a Park brake warning system. You may find that the wires are spliced somewhere already.

 

Don't worry about pulling your frunk relay panel to pieces again. I managed to find an OEM USA diagram which had colours which matched your car (for the foglight wiring). In the diagrams I found, the white/red wire does go to a different pin on the LH instrument panel plug, but that makes perfect sense because of the relocation of the light on F1 cars.

 

I don't know if you want to modify your pin numbering chart in post 51 for the F1 connector...

The WSM F1 Gearbox section has this diagram ...

Which makes the pin numbering like this:

You have white/black on pin 1, not pin 7, etc, with the unused pins pins on 3, 4 & 5 (instead of 10, 11 & 12).

(Just in case you get confused later).

The instrument binnacle pin numbers 13, 2 & 11 shown in the WSM F1 graphic above also match with the pin numbers on the OEM Lighting Wiring Diagram's instrument panel left hand plug ("D") reading left to right.

Anyway, we are probably a little off track from getting your brake light to work ...

 

I don't know if there is a lamp installed in your BRAKE light, but you might want to try putting a small voltage on binnacle pins 7 & 6 to see if the brake light lights up. This is assuming there is a pin installed in position 7. Pin 6 is pin 8 in your table (green/white wire).

 

The reason I pulled the dash pod was to check for the bulb. It's there and works.

Let's use your pin out numbers going forward. I just made that table so you had the correct colors.

So power to pin 6 & 8 on the 13 pin connector socket?

I do not see a pink wire on my harness. just a pink / black one

 

I do not have this wiring diagram...is this a new one?

 

6 & 7

6 should be green/white on the harness side. 7 has no wire on your car.

 

That's a new one I'm drawing (with your info).

Here's a link:

Unfortunately, I'm running out of room on these diagrams for these additional F1 wires.

 

Yea, I caught that. ...and yes 6+7 gets the brake light to come one.

 

Excellent. thank you.

Now all I need to know is where the wire comes from to go into the #7 connector.

I have no idea why I do not have anything there. I looked down stream and do not see a pink wire anywhere.

 

Weird. Surely it can't be standard on the F1 car. That would be dangerous not to have a brake warning light.

Here's an updated simplified F1 diagram:

Where does pin #7 on the 13 pin connector got to on a non-F1 - 5.2 car?
