Click here to purchase Used e30 euro clock
This page is dedicated to helping you wire your European analog clock into an E30. This is a sweet addition to our US/NA spec cars! Euro clock upgrade will also fit e28 cars.
Tools needed to install euro clock
- correct harness plug (included in our kit)
- flashlight
- small Phillips screw driver
- Phillips regular size
- flat head regular size
- tools to remove your head unit (head unit specific)
- connectors
- wire cutters
- wire crimper
- philips screw driver
Step 1: OBC removal
Start here
Step 2: Remove radio
Remove face plate and trim piece around radio.
You are going to then need to use the tools (from your head unit) to remove the head unit
Plug the tools into the sides of the head unit. Once they click pull the head unit outwards slowly. See picture below.
Unplug the wiring harness from the back of the radio (along with antenna). Its easier to have these things out of the way.
Step 3
Pop out the switches from behind
Switches popped out
Unplug them because the screws needed to remove the panel are behind them.
next remove the control knobs for the vents
and the heater selector knob
Step 4
just pull directly outwards and they pop right out
to remove the plastic panel there are 2 ways to do it.
most people can get by with protecting there flat screwdriver
with some electrical tape
prying the panel outward
option two is a dental pick with a hook on one end
Step 5
insert the hook end into the panel and pull outward
once the plastic panel is removed you have access to the screws
remove the 4 screws
Step 6
next there are 4 screws holding the entire radio/hvac panel in place
top right screw
different angle
Step 7
bottom right
this is why you need a small Phillips not very much room to work in
another angle of the bottom right
Step 8
bottom left
another angle of the bottom left
Step 9
You also need to pop this switch out
this can be done by pushing it out from behind
the narrow plastic panel underneath the instrument cluster
overlaps on to the radio/hvac blank that we are trying to
remove. you need to sneak this out by pulling the radio
panel out more on the right side then the left.
Step 10
right side out before the left side
Step 11
now that its almost out you need to pull on the connector in the
red circle its the fan speed switch
pry the green connector plug out by fitting a flat head screwdriver
on the black tab on the green connector and wedge it out.
Step 12
Step 13
put the panel on a table or work space
remove the 4 Philips screws indicated by the arrows
this removes the obc from the panel
If your car came with a 6 button obc, the bracket is the correct one that holds in the euro clock. Simply switch into your e30 clock.
