For the door locks you need to go into the drivers door I believe. You need a relay and a few diodes. If I can find the tech sheet I have i will send you the info on that also. It is the same method you need on the 01 Lexus RX330, and the IS300.

I've never gone into the drivers door for a Highlander before?! I've always went for the wires in the passenger kick: Lt. Blue, White, and Brown I believe. No relays just 2 diodes if I remember correctly.

You can go to the passenger kick, but the advantage of the drivers door is 2 stage unlock. It's a double pulse there, first unlocks drivers and turns off alarm, second unlocks all. The passenger kick doesn't do this.

I went with the omega Data buss for the 2005. This is the best invention for these type of vehicles.

The passenger kick just dis-arms and unlocks all with just 1 pulse then?! Im not saying your wrong, I just never noticed?!

Notice if you turn the key in the passenger door it unlocks all first turn.

Hi All,

I am trying to locate the VSS (Vehicle Speed Signal)lead a.k.a Speed Pulse Signal on '06 Highlander. Please help. A diagram of ECU with pin no. for all VSS signals would be really appreciated.

Thanks,
Steve
