DRL in Yaris from..?

[CTScott]

The headlight switch switches the ground side. The bulbs have power going to them and then the switch makes or breaks ground to the other side. The DRL relay pulses that ground making it look like the bulbs are being run at 1/2 voltage. The relay kit should make it where the other side of the feed is ground or no connection, not the pulsed ground.

So the answer is YES, I do have to order relay kit if I can't remove the DRL module.

Does that relay kit look right and working which I posted few messages before?

The relay harness gets power directly from battery but normal bixenon system do the same. Basically there is no difference by using original h4-bixenon system or relay harness. Both get the switch from car's original h4 socket. So what is the difference?

Maybe I am stupid but I don't get it... anybody help

CTScott said that DRl pulses the ground side. Yes but the control still (even with the relay) comes from car's own wires which is connected to DRL, that is why I don't get it how the relay changes the problem. Both get the control from cars own wires and so they are both connected to the DRL

This seems to be my monolog but, I get the fron dash off with CTScott instructions! That was easier than I expected and the DRL was right under the dash. Thanks!

I found the DRL module with number: 82810-52020
whic differs from DIY instructions (http://www.yarisworld.com/forums/showthread.php?t=894). In this DIY number was 82810-52040.

I think that module I found is DRL because google search:
82810 RELAY ASSY, RUNNING LIGHT
82810‑52020 NCP1*, NLP10, SCP10..JPP..LHD..(LUNA, SOL, TRSTD, TS) 1

So, yei! Problem solved (hope so..)
