I’m in the process of rewiring the car. Found this under the dash and can’t figure out what it is. 1966 type 3 notchback
Any help is appreciated. |

Would you happen to know what the terminals mean? Cause all I’ve searched about that they don’t have l1 l2 l3 l4
I couldn’t find a wiring diagram that referred to those terminals |

Did you check the wiring diagrams in the Technical section?
And, oh, welcome aboard. |

It's a 12 volt relay. No idea what it does, as most 66 type 3s are 6 volt. My first guess is that one of the cars PO's was trying to fix an electrical problem and didn't know what he was doing. It wouldn't be the first time something like that happened. At this point in time, it might have been an "extra" part he carried out to the car, and just left it behind. _________________ Bob 65 Notch S with Sunroof

I dug around in my pile of junk and found a 91/18 relay. It looks like a 91/17 except it has push on and not screw downs.
According to the what someone wrote on the side, 98/18 is for Fog lamps and fanfare horns. The diagram on top is almost identical except it uses 80,85,86, and 87 instead of L1, L2, L3, and L4.
OR
Just a Flashing relay

Instead of starting a new topic, thought I’d jump on here, since my question is kinda the same. Found a box of engine tin and noticed something new (to me)
The one on the left is two pieces.
What’s that from? _________________ Everything known to man has been written.

91 indicates lighting system. 30 is battery +, 31 is ground, L1,2,3 and 4 are light out terminals, S1 and S2 are signal inputs to energized breaker points. Looks like what we have here may be an early add- on hazard flasher unit. Only USA cars (and maybe Canada) got these in 1966/67. Since the NB was never officially imported, this may have needed to be installed to get it into USA. This could explain the screw type terminals- this could have been sourced from an aftermarket accessorizer prior to importation.
M630 was for 12 volt electrical systems, first available optionally in 1962 if memory serves. _________________ Немає виправдання для війни! Я з Україною.

I don't think it's a flasher, my bet is fog lamp relay _________________ 1965 Volkswagen 1500 Variant S

They are "widened" by the factory to fill the wider engine compartment introduced in August 1963. |

I think mine are not the widened style ('71). Are you sure that's it? |

Your 71 would use 1 piece already widened cooling tin. _________________ Bob 65 Notch S with Sunroof

The original piece in question is a 64/65 piece and is a cross over from single side draft carb to dual carb. The SSD trim was adapted for the dual carbs. The engine bay was widened due to the dual carbs in 63 as said. Anyone who has stuffed a dual carb motor in a 62/63 knows how tight it is already. If it had the electromagnet cut offs it would hit the engine bay metal - necessitating the removal of the cut offs. Even the carb linkage may hit. So when the engine bay was widened the tin was widened - Single port - two year only modified tin. _________________

Used until the heater system was modified to include thermostatically controlled mixing boxes, at which point they redesigned the tin and elbows sometime in August 1964. So the modified wider tin was only in use about a year. _________________ Немає виправдання для війни! Я з Україною.
