Notes:
NOTE: Some models have an immobilizer system that needs to be bypassed during remote start. Use DEI module 555F or 555U to bypass. *1 they will test only by operating the key in the passenger door lock cylinder, not the rocker switch on the door itself. *2 door lock ECU and theft ECU are in the center console. *3 located at one of the coils on top of the valve cover, use the wire that is NOT BLACK/ white, WHITE/ black, or black *4 rear wiper pink/black(-) at wiper switch *5 rear open & close motors are common through the switch *6 sunroof relay located front center under headliner. *7 stereo amplifier in center console below doorlock and theft ECU. *8 the integration relay is at the bottom of the fusebox. *9 This is for the power sliding side door.

Those and the 2003-and-below colors, and they are wrong.

lburrowes: You already asked this same question in another recent post.

--Someone there already answered you, although the information he gave is very basic.

--I answered you too, and reminded you that you could do a search. And the rules here say to always do a search first. And you still apparently haven't done a search. If you had, you'd find that this same question was already answered a week or two ago.

Sorry if I seem grumpy, but it makes me not want to come here anymore if it's only to answer the same questions over and over.

But anyway, I have fully researched a few of these Siennas myself. Here are the results:
