The rearfoglight isn´t existing on us-neons. The switch is included at the
multifunctionswitch on the export-neons. There are three different MFS
1. us - only front fog
2. export - only rear fog
3. export front and rear fog
The functions are controlled electromechanicaly, by pulling the knob on the left
the front foglight will be switched on, if the drivinglight is on.
This is realized with a little plastic gear (see the MFS on top of the picture,
the lower is without)
This gear is always worn
and needs a little fixing
This gear isn´t existing at the export-MFS with only rear-foglight. If you pull the
knob on these, no front-foglight is switched on. If you pull and turn the knob, the
rearfoglight will be switched on when a stem is pushing a bridge inside which
connects the power.
The export-MFS has that gear and the option to turn the knob.
If you like to add the rear foglight you could either install the MFS
with both positions or you have to get a MFS with just the rear fog-option
and take the gear and board from your original MFS over. So you will
be missing the front fog symbol, but it´s working anyway.
(see in the picture the upper board out of the MFS without front fog, and the
lower out of the MFS with - you could recognize the little copperbridge
which is included here)
The rear foglight is wired by two cables (wt/br) within one cableshoe at pin 12
at the MFS-plug
once to pin 1 at the clusterplug for the rear foglight signallamp
and the other to the rear foglights
original routing
The fuses are a bit different at the export-Neons. At pin13 of the MFS-plug
a wt/org. cable goes to fuse 20 at the fusebox. Either you like to change that
wiring, too or you take the cable for forcing a relay which connects the rear foglights.
The SXT instrument cluster already has the socket and the symbol for the rear fog
signal lamp. Just install a lamp.
At the SRT-Cluster the socket should be there, but not the symbol. It is blacked out,
so that you have to polish a little circle if you like to get the signal function.
How To: Multifunctionswitch-mod for bux rearfoglight
What works for SXT will work for SRT as well.
Only thing is, that the windows where the controllamp should light through is black. So you have to scratch it a bit and you get a controllamp for whatever you want.
In my case I have to get one for the rear fog.
short:
- took bux MFS with rear and front fog
- doublewire inserted to PIN12 of MFS-plug
- one to the fusebox on the left, the other to the rear fog
- other wire to PIN1 of clustersocket
- lamp into free socket of cluster
- scratched
