automatic headlight add on (DEI 545T nite lite)

[transcon]

Trying to install automatic headlights on a 2010. I'm not sure about some things. Need to connect device to... Parking light in and out. Headlight in and out. Constant power and power when on.

For headlight it seems red wire (in) and green/ blue wire (out) off of 31d low beam headlight relay.

For constant power: red wire off of ignition switch.

For power when on green and yellow off the ignition on switch

For parking lights I don't know. Can't seem to find a relay for them only fuses.

Any one install one of these or know where the parking light relay is?

Hello transcon. You must have missed my reply to your original posting on 12.26, There is no parking light relay. Power is turned on and off by the main light switch.

Behind the battery in my 2012 is a fuse block. There were three tiny relays in a group that is nearly a square, not quite. Your local dealer probably has a few of those relays in stock for thirteen bucks. I simply plugged one in to complete the square arrangement.

Headlights now go on with the ignition with diminished power (no taillights), off again when I switch to parking lights (taillights DO go on), and of course switching the headlights on gives me full-power headlights and taillights.

197-type LEDs are available on Amazon, about $13 for ten. Note that since LEDs only work with proper polarity, I had to rotate 180º experimentally to get them to light up. LEDs make the parking lights very visible during extended dusk time and driving through intermittent shadow under trees.
