I have a '74 914-4 that did not come with the optional driving light set and wish to add them to my car. The 73-76 914s came with pre-installed wiring exiting from behind the front bumper, from my understanding, that would allow lights to be added simply by installing and connecting them.
My car seems to have these wires, as expected, but due to paint overspray effects, the wire colors have been obscured, making it hard to determine which is the brown GND wire and which is the black (+) wire. I'd appreciate any help available advice from others who have retroactively installed the accessory (OEM type) driving lights to their cars. This might simplify my efforts considerably. Also, my car's horn was removed and I wish to install a set of the HELLA OEM type dual-tone Superlouds. Again, the wiring is oversprayed by body paint, so any way to quickly determine what wire is the brown GND and (+) power wires for the original (now removed) horn? Is the original horn relay located on the engine-bay relay tray or somewhere else on the car? Thanks.[font=Verdana] |

That would be dandy! Do you have a set of two? Or just the one? |

That would be dandy! Do you have a set of two? Or just the one? PS: After even further investigations, it seems that the 'supplier' of my fog lamps, despite stating that they would come with the 'correct' bulbs, failed to include them. I now think that the JAHN BA20s F2 bulb DOES fit but I just didn't buy the right size 'equivalent' bulb at my local store. O'Riley Auto took the "BA20s F2" spec and handed me a bulb with the same V & W rating but with a smaller bulb base. Groan. Fortunately, I now have some JAHN BA20s F2 bulbs on the way from a different supplier, so we shall see if they fit these sockets as they are supposed to. After examining all the on-line articles I can scout out on the subject of 914 fog lamps, I found none of them contained ALL the needed and necessary information about the lamps and ALL of the installation tips necessary to successfully 'retro-install' a set on a car that didn't come with them. Too many of the existing articles assume a level of familiarity with the lights many of us don't have and slip over what they may consider 'obvious' points to consider, but that to an 'amateur' may need careful explanation and background info. What I've learned thus far by the 'sniff-out-and-ferret' method is that 1) Porsche 914 fogs/driving lamps came in two types, the Tungsten bulb type and the Quartz Halogen type. 2) the Tungsten bulb type had just the one bulb socket size, specified to take the JAHN BA20s F2 type bulb (which is not the same as the modern, same V & W rating equivalent). 2) The older JAHN BA20s F2 bulbs are not easy to find these days, although a few specialist sellers carry limited quantities of them (I managed to find several, which meets my current need, no pun intended). 3) Quartz Halogen type lights are better for obvious reasons (55 watts instead of 35 is one), so assuming all other things are equal, the Quartz Halogen 914 fog/driving lamps are preferable for retro-installation to the Tungsten type. All that said, I'm happy enough with the old Tungsten type bulbs, since I rare ever need extra-bright auxiliary lighting. Sooooo...once my REAL BA20s F2 bulbs arrive, and once the spare bulb holders I need arrive also, I can finish up this rather frustrating 'trial-and-error' exercise I've undertaken. [Spare Tungsten type bulb socket holders are also hard to source out, although again, a few specialist suppliers may still offer them; I found a couple, fortunately.] Final thoughts: It would be GREAT if some enlightened soul would take it upon himself to write up a truly comprehensive tech article on this subject, including all the trivial details that too many take for granted, and publish it somewhere (like 914World or The Samba, or Pelican Parts) so that those of us who are about to struggle through this 'retro-installation' ordeal will have ALL the info they need in one single place! [But I'm a forlorn idealist who also wishes we had peace and wide-spread intelligence in our world, LoL! (IMG:style_emoticons/default/drooley.gif) |
