Wires Inside the Yaris & What They Do - Page 3 - Toyota Yaris Forums

AlexNet0 · 09-19-2009, 08:09 AM

use a multimeter and probe the wires, and make your own diagram, thats what I did when I installed my remote starter.

Yes. That blue +12 is always on though. The pink is switched ground for the inside lights.

There's a 2 pin connector to the engine coolant temp sensor. It has a pink and a blue wire that go to pins 96 (pink) and 97 (blue) on connector C20 of the ECM.

With the hood open it is to your left (the car's right) against the firewall. It is the big silver box with the two large connectors.

The easiest place to tap it is at the speedometer. It is the pink wire in pin 17 of connector D1, which is the larger of the two connectors.

Pop the trim from around the speedometer and you'll see two connectors going to the cluster assembly. If your car is left hand drive the connector you want will be on right and if it's right hand drive it will be on the left.

I want to wire up some aftermarket LED driving lights. I want them to come when the car is in drive. Is there a easy place to connect them? 2010 5 dr HB. Thanks.

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.
