Well, after a successful installation of DEI 545T (Successful installation of DEI/Viper 545T Nite-Light system in a 2007 EX-L), I decided to do another MOD which is installing DRL. I happen to have seen the 2006 DRL wiring diagram and proceeded to do my own modified version.
I did NOT use any resistor. Following HONDA's design, when DRL is activated, the 2 HIGH BEAM bulbs become connected in SERIES instead of the usual PARALLEL, hence each bulb is illuminating @ 50%.
1.) 3 SPDT 30A automotive RELAYS
2.) 1 inline mini fuse holder
3.) #16 stranded automotive wires
4.)1/4" black split wire loom (to match what's in the van)
5.) assorted sizes heatshrink insulators
6.) soldering gun/lead
7.) black electrical tape
8.) black plastic enclosure for the relays ($3.xx from Radioshack)
10.) 2 pcs. DIODES
It took me about 3 hours to do everything. The hardest part was figuring out how the relays would be used.
****REMEMBER TO DISCONNECT THE MAIN GROUND CABLE FROM THE BATTERY before doing the installation. Make sure you have the radio RESET CODE..*****
There's ONLY 1 wire that needs to be CUT- it is the black wire (ground wire) of the PASSENGER SIDE HIGH BEAM.
-I got a SWITCHED 12 volts source from the YELLOW/GREEN wire under the MAIN UNDERHOOD FUSE BOX. For the CONSTANT/LIVE 12 volts, I tapped from the big BOLT on the right side of the MAIN UNDERHOOD FUSE BOX.
-It is safe to use a plastic enclosure because the relays and diodes do not get warm/hot at all...
-When I'm not busy next week, I'll look for a good route for running wires thru the firewall so I can install switches and be able to conveniently able/disable the DRL.
I know my ODY needs a carwash..
