Wires Inside the Yaris & What They Do

To have them come on when the car is "In drive" with an automatic transmission, you could tap the connector C27 on the transmission. The 10A Gauge circuit feeds through the Park/Neutral/Position Switch on the A/T to feed the indicator on the cluster and the ECM with the position of the A/T shift. For low power lights (LED lights under 1A) you could feed them directly. For high power lights (incandescents or HIDs) you would have the Drive indicator feed the coil of a relay, which would then have it's own power feed for the lights.

C27 is the 9 pin connector on the front of the transmission (by the shift linkage). It has a row of 4 and a row of 5 pins. The center wire (light blue) on the 5 pin row is the "Drive" indicator wire. It will have 12V on it when the shift is in drive. For ground, you can grab a chassis ground, like the ground bolt under the left headlight.

Hihi, I already tested the wires tat u mentioned in the picture.. The blue wire does give constant 12v and the pink wire should turn on the lights with the door right?
I already tested the pink wire by multimeter and it will only give 12v when the door is closed.
So may I know what can I do in order to get 12v out when the door is open because I want my led to be on only when the door is open...

Thanks...

Use the pink as ground and the blue as your +12V.

This way you don't have to go into your engine bay to wire them up

Thankyou ThankYou THANKYOU!!!

Thank you, The Architect. I installed a remote starter today, first one i have ever done. It works great! I could not have done it without this thread.

Hi all. Is there a place I can tap into the engine bay for turn signals besides the wires that lead to the signal lamps?

You can tap into the turn signal wires in the under hood fuse panel. On connector B13 (left connector in this picture), the light green and dark green wires in the upper row (next to the two red wires for my fog lights) are the turn signals. Light green is left, dark green is right.

One more question, where can I tap in for the parking lights - the lights that go on just before I turn on the headlights?

The White wire next to the blue and orange on the headlight stalk connector. You ground the wire to make the lights come on.

Sorry, should've made my question a bit clearer. I'm looking to see if there is one in the fuse box like the one pictured above.

In the fuse panel, it is pin 3 on Connector B13, which is the green wire next to the two red wires in my picture above. If you don't have fogs installed, the place where the two reds are in my picture will be empty on yours.

Hi to all... just a noob here in M.E., just wondering if I tap the leads (+,-) of an LED light to the pink n blue from that pic above, will the new led light acts the same as the dome light? will the new led light dim to off as well upon turning off the ignition? Or just turns on when the doors were open? Sorry to much question. Need help where I can tap my led lights so that it behaves the same like the dome light, using its switch also to turn on my led lights underneath. Thanks so much. -jon

If you tap the pink and blue, the LEDs will behave the same as them dome lights, provided that you leave the dome light switch in the "Door" position. If you manually switch the dome to "On", with the doors closed, the LEDs won't light up with the dome.

The black one is for the Door lock receiver. Does your Yaris have a manual or automatic transmission. If it's a manual, then the other two are for the A/T shift illumination and for the shift lock control ECU.
