 |
|
Hey guys,
I have a request for all of you. I need help with an alternative route to wire my Hella reverse lights on my 65 beetle.
I know the typical wiring method for Hella reverse lights for beetles. Wire from the coil, to a fuse, to the switch on the nose cone of the transmission to the light assemblies (lights providing the ground to the loop).
Here is my predicament. I am not running a coil on my current motor. I am going the EFI route and I am running Coil Near Plug ignition setup utilizing LS2 Coil Packs. So I don't have the ability to wire my lights to the traditional coil setup.
Could anyone help me determine an alternate way to wire them?
Greatly appreciated! |

1. You could run a wire from a switched position on the fuse box back to the reverse switch on the transmission. I'd recommend to use an in-line fuse with this too.
2. You could run a wire with an in-line fuse from the starter big wire to the reverse switch on the transmission. Just don't leave the VW in reverse when you park it.
Questions: 1. How does your electric choke get its voltage? 2. Does your '65 still have a voltage regulator mounted on the generator?

since it's EFI, he doesnt have a choke, and probably isnt running a 6v generator either... just sayin
the reason they usually run off the coil is because it's easier than running a dedicated wire. So just run a designated wire off the ignition switch, all the way to the back. Or from whatever is powering (key on) your EFI really

Erik is spot on. No choke, No 6V, and I am running a 12V alternator, so its internally regulated.
There will be a handful of 12V relays under the back seat that power will be sent to to power the ECU under the back seat. I will take a look at that, I could easily run it from the relay and then whenever the key is on, the reverse lights will have juice.

I had considered the possibility of running it to the starter or straight to the battery, but had a feeling that would result in leaving the reverse lights on when in reverse since that method would always have juice to it. That would not work for me since I have a Berg locking shifter.....that locks in reverse. |

this (what I bolded above). this is the whole reason they originally used the coil wire for power, with the switched wire from the trans (or the spedometer unit above, but those are not as good and take you actually rolling to get it to light up)
there is this one as well

| Erik G, where did you find that reverse light switch off the shift rod? |

No doubt that's the best solution.
But - the oil pressure switch has power when the key is on. If you use it as the 12v source the OP light might come on on the dashboard when you put it in reverse. Then you would have a reverse warning light.
