Highbeam 50% DRL mod, completed

Has the new module arrived? I'm curious to see how well it performs.

 

I'm going to go ahead and say this is way too much work.

 

Hi xliderider thanks for your review.
I bought the same module which i have already in hand but i'm waiting for the delivery of the 9005 harness because like you i do not want to tap in the original harness.
I would like you to clarify some things please to facilitate installation as the instructions aren't very intuitive. The power and ground wires are straight forward. The purple wires are tapped onto the highbeam. The green wire which as i understand will signal the module if lights are turned on or off, where did you connect it ? Then there are another two wires Black - Optional power "after the ignition" and White - Ground after switching module which seem to be optional. Have you connected these two?

Many thanks

 

Managed to install the drl module, pretty straightforward and functions as expected.
Xliderider thanks for your guidance! One question for you perhaps you have a good suggestion.! I d like to change the high-beam bulb to get a whiter effect, do you have any recommendations? Heard/read led alternatives are not good enough for high-beam?! Thanks for your feedback

To test the installation i temporarily connected the + red wire directly in a free slot in the fuse box as seen in the pic attached. This however is temporary and hemce i need yor kind advise as to the best and proper way to connect to the supply. Many thanks

 

Thank you for the great updates!

I thought I'd mention since I finally got the courage to start up again and you said to let you know...

I purchased a fuse box from a salvaged Prius c because although I was able to get the Toyota part number for the relay block, I could not find any info on the harness pins necessary to put into it. I carefully extracted the relay block and some of the harness, (the rest was cut off as I didn't really want buy the whole harness for the car.) Next step is to try to see how to carefully open up the fuse box.

Will continue on the Prius v forum....

 

Thanks for the well wishes!

The relay has a total of six wires. Not too far off from your install. The rest of the wiring I kept because I don't solder/crimp well, and wanted to keep my options open. (It's harder to diagnose after I've crimped/soldered because I've done such a lowsy job in the past that that was the cause of failure.) I can run the wire I kept to the respective places in the fuse box, ie. the H-LP RH HI and H-LP LH and keep the original in tact. Looks like there is an open "FLF-S", (I am not familiar with this fuse type so I had to look up fuse images,) slot in the fuse box. I will test if it has voltage. If it does, I will only possibly need to cut one wire under there and connect that one, the output from main body ECU to turn on the high beams, or I may just run wire with the other I have to run to the DRL output and disconnect the original at the ECU. Then the original harnes would be left intact, and I can put it back to the original if necessary.

 

I just found this information because I subscribed to TIS for 2 days. If you are having trouble matching the color/intensity of a Toyota DRL system with the green relay in the fuse box, it's probably because that pulsed square wave, actually it looks more like a rectangular wave with long side going up, changes with the ambient light sensor. It says the period decreases, essentially the frequency increases with higher ambient light. Neat stuff....

 

Something strange is heppening to my drl lights! When i installed and tested them in the garage all seemed working to perfection but now on daily use i sometimes have found that the lights go off. So i startred monitoring! The drl are alwyas on when i start but some times along yhe route they go off. At first i thought that this happenss when i press the park button and i was almost sure that this was the cause as i saw it hapenning once. Just a few min ago i was driving behind a car and i could see the reflection of my drl lights on this car, then all of a sudden they went off. I have not tried it but probably if i had to switch on the lights and off the drl lights would come on!

My installation is simple, 12v connected to fuse box, ground to car body, green wires to parking lights. I have not used the black and the white cables. Perhaps i should use the black ready signal cable?

Many thanks for your help

 

Probably voltage fluctuation is turning it on and off. The battery is really small, I just realized yesterday, and has special charging instructions. I agree you should connect the ready wire....

If you like a switch like xl's you can try 00016-32270-05. It's in the DRL kit SET sells. The instructions are available on TIS. Call dealer for availability first though.

SCH-R530M ?

 

Where is the easiest ready signal ? I seem to remember reading in thus forum attaching to the windscreen washer pump!?

 

Since I don't know where you put your DRL box/unit, I'm afraid this is an extremely hard question to answer, that and I'm afraid the wiring in my car is different and I don't have the wiring diagram, it'll cost me ($15,) to access TIS. (Wish you asked me last Thurs. or Fri. when I did.) You took a picture of your relay/fuse box. those clump of wires in the lower left of the picture you can check for ready signal with a voltmeter. (Sorry if it's already obvious, but 0V when ready light in dash is off or 12+V when ready light is on.)
