ELOJR has a euro spec rear taillight assembly, not sure if hes going to sell yet but I was wondering if it would be possible to make it work. Its appairently an ordinary light but the reverse lamp is red...for the european spec rear fog light I figure I can hook up a small toggle switch in the cabin, get power from (splice) the rear parking light and just run it to the back up/fog lamp. This way the back up lamp would still illuminate when car is in reverse, albiet it will be red, but also illuminate when toggle switch is activated.
thanks

I went ahead and installed sylvania Silverstar 7506 bulbs and they do seem a little bit brighter. Now Id like to ask anyone that has access to a wiring diagram... what color wire carries juice to the d/s rear parking lamp? Or anyone know a link that has our wiring diagram?
Thanks

I talked with our maintenance tech at work about splicing from side marker or tail light to the d/s back up bulb and rnning it all from a seperate switch. He mentioned the possibility of a back flow of power from the splice, up the car's origional reverse circuit wire. He said to install a diode between the splice and the origional reverse wire...upstream so to speak.
I have a basic electronic understanding but am unfamiliar with diodes and such. Guess Im gun shy because of all the car's computers etc. Any input would be appreciated.
Also, am I correct that the light out warning lamp wont tell if a reverse bulb is out?
Thanks
PS BTW...Im eyeballs deep in xf wiring diagrams which I am learning as I go, like learning algebra in one day. Forgive the barage of questions

It is really easy actually. You need to diode isolate the light bulb by taking a diode and putting it on the positive side of the light bulb between the car and the other power wire you have coming in for the fog light switch.
Code:
diode-------------------------------, V backup light 12vdc -------------===----+-------tail light---------------ground(-) | fog switch 12vdc--------------------------'

heres some pics, Ill add info later
most 7.5 fuses are on when lights are on so no worries that you could accidentally leave the rear fog on. Im using a 2amp inline fuse cause thats all I had lying arond

Check depth of toggle. theres a small rectanglar opening next to the car's light switch and a misaligned toggle switch may prevent the panel from popping back into place.

I used a stone grinding cone to make short work of the plastic...actually got it lined up ok
![](https://www.crossfireforum.org/gallery/data/500/medium/PB220452.JPG)
be careful running it up here, the seaatbelt swivel get close but no big problemo. pull kick panel and run wire up to fusebox
![](https://www.crossfireforum.org/gallery/data/500/medium/PB220451.JPG)
1/2 way done, theres 3 bolts adjacent to the fuse box for an easy ground point, you can see my black wire going up behind the weather stripping to them

a 3 amp diode given to me by friends at a stereo shop

Rear wiring splices brn is power to rev light, white is to toggle switch, diode wired in with crimp connectors.![](https://www.crossfireforum.org/gallery/data/500/medium/PB240461.JPG)
Hey, it works...now to wait for european tail lamp with red rev light!

bump...Received my euro taillight from EOLJR (Thanks
) Quickly ran out to the garage to get it installed. In my haste I put the power to the wrong side of the diode
dud, took me a bit of head scratching to finally figure THAT out. Shows to go ya that haste does indeed make waste. With paitence and a new toggle switch, burnt the old one out some how, its good to go. I'll post some pics today after work. Again, thanks to everyone for help with this mod

The real reason I'm posting in your thread is a comment on your comment.
With the pittance of concern for our cars at the dealerships, this forum IS the beacon of light in a stomy night for many. I try to add as much info as I can when I find a way to improve the ownership experience for everyone.
I'm happy to see you join the ranks of contributors! Thanks for the post.

You can see the extra provision for the indicator lamp (see attached).

OK this project is done! Here are some pics of the final deal along with one of my newly installed GAP chrome side strakes

you can barely notice the l/r reverse light isnt the same color as r/r
![](https://www.crossfireforum.org/gallery/data/500/medium/PB290488.JPG)
Close up of it on in daylight, its as bright as a brake light and contrasts nicely to the dimmer parking lights.

Actually found them in a flea mart for 1.50 and thought, ok. Was later on I discovered that they are ford. They do get lots of positive comments at shows though.
