[s-cars] Blau Headlight Harness Instructions?

[weski at verizon.net]

Mike,

I had this harness on my S6 for 10+ years.  I don't have the 
instructions but I can describe it's basic procedure.  I also don't have 
the harness installed anymore.  Blau touted the harness to protect the 
light stalk on the steering column from shorting out but mine shorted 
out anyway over the years.  Too frequently the relays built into the 
Blau harness burned up due to not being weather tight yet located under 
the hood - I had various headlights go out 4-5 times per year every 
year.  To me it wasn't worth the hassle and it didn't protect my light 
stalk as it wore out anyway.  Since I removed the harness I haven't had 
any headlight outages (of course this was after I replaced the light stalk).

One more comment about the Blau harness and then I'll get back to your 
question.  For me, I got the harness to address the E-Code headlights 
with built-in city lights or DLRs.  The stock headlights and E-Code 
headlights all have 5-pins on the housing connector.  The US-spec 
headlights only use 4 pins - Hi, Low, Fog, and Negative.  The Blau 
harness includes 5 conductors to activate the city DLRs spliced into the 
parking lights for control.  Since I removed the Blau harness, I just 
opened the stock headlight wiring connector and added a 5th wire lead 
for the city DLRs.

To connect the Blau harness, you disconnect your stock headlight harness 
from the headlight housings; connect the passenger side stock headlight 
harness to the Blau harness to provide control to the relays.  Then 
route the Blau harness to each headlight housing (I ran mine under the 
radiator support).  Then the Blau harness needs 12V power and ground.  I 
ran to the Positive post under the hood on the passenger side firewall 
and found a bolt on the cross member under the radiator for the ground.  
My issue was always with where the relays are located and with my 
installation they were under my passenger headlight and they constantly 
got wet and shorted  out.

My E-Codes we 55w H1 and H3 bulbs so they draw the same power as the 
stock 9003/9006 bulbs so the relays weren't really required. Not sure 
which wattage bulbs you will be using but if you stay 55w you probably 
won't need the relay harness.

Good luck,

Paul
