Auto headlights.

Part 2 of the day!

Been wanting to do the auto headlights kit to the car since I got it, really annoys me that the lights don't turn off with ignition, did with the RAV.

Using the DEI 545T module, took all the wires out of the loom that I didn't require, you can set it up for continual lights on or have so the ambient light sensors works. I took out the wiper and alarm activation wires, which left me with the constant, ignition sense and ground out of the main plug. the second small plug is the relay activation loom, I used the DEI relays because they came with it, but really you could go for micro relays as there's no substantial current requirement.

The kit with the two main looms with just required wires. The red wire in the module that I cut disables the headlights being on all the time.

Sensor position, the car's got a neat recess for the light sensor.

When you take the panel on the right under the start switch off, I simply sat the module with double sided tape flat to the plastic below the opening and mounted the relays on the metal strap just inside.

When the steering wheel cowl is off I accessed the wires from the lighting switch direct. You switch ground with the relays, so connect both brown/violet to ground (they'll have the fuses on them) and put green (from DEI relay) to the black wire at pin 4 which switches the headlights, and pin 9 to the blue (from DEI relay) which switches the park lights.

Best thing, unlike the Swift which I did last week, if the lights are activated by the module you can use high beam without having to switch the headlight circuit in (ie. turn lights on manually). The ECU picks up lights are on and allows high beam to work. I took ignition sense from the wiper block on the plug on the left hand underside of the wheel and it's the blue wire there.

Really pleased, as you don't need to touch light switch at all. I've got an illuminated round rocker switch coming to place in one of the four panel switch placements so you can sit with motor running and disable the auto circuit. Do that by switching the ignition feed to the module.

Pretty cool dude... Been wanting to do this for a while on my car.... How long did the install take?

Well, you won't end with a footwell fulla figures like I did nutting out..

So I guess 1/2 - 2hr max. Using my supplies you'd go to head unit constant easy to get to, and all other wires are at the wheel! O and you cut the sensor plug off slip the wires through the dash, mount the sensor and reconnect the plug.

Got my kits through Amazon, pretty quick and cheap as well.
