Hello all,

A quick search of this area yields nothing on an install for a Highlander. I've got an '07 with the base sound system, and I have a D3 on order to arrive soon.

I am looking for info on where to tap the VSS and Backup wires (yes, i will be using a backup camera), and if anyone has any helpful ideas on running the GPS antenna.

Now, I know most toyotas are nearly identical (a 4runner is almost a highlander in terms of installs), and the electronics don't vary much between years / models, so any helpful advice from fellow toyota owners would be great.

Thanks in advance!

look here

not sure about 07, but if it hasnt changed from 06 its:

vss-yellow at the ecm behind glove box, second plug down pin 17

reverse-red/black or pink, drivers kick panel, 14 pin plug, pin 10

^^^He's right 07 is the same.

Is there any difference for the hybrid? For the reverse, I have an 18pin blue plug in that area... I found a link that suggested pin 11, pink, and tried that with no success. How can I tell in the Z2 if the reverse is connected? Is there a test anywhere within the system?

Thanks - this forum rules!

Check the connection status menu. It should say low when the vehicle is not in reverse and high when it is in reverse.

I get low, and low... no dice... any suggestions on how to determine which wire it is?

this is the link that suggested pin 11, of 18 blue plug:

Thanks for your help! Now I'm hunting down the vss...

"Rent" a multimeter from sears or radioshack if youdon't have one and start testing the wires.

doesnt a multimeter need to touch bare wire? i cant turn the stupid car on w/o the plug in - so i can test via the connectors....

I'm regretting doing this installation myself - LOL

you can slide the probe into the harness and as long as you touch the metal of the pin you'll be fine.

my stupid hybrid will not turn on with the harness out...

You don't have to disconnect the harness. Like I said just slide the probe into the harness. If you look closely at the wire side you should be able to see part of the the actual pins attached to the wires.

Just as an update, here's what I have for a 07 highlander hybrid.

Reverse Light red/black to pink + driver kick, blu 18 pin plug, pin 11

If you're looking at the harness the wire will be red/black on one side and pink on the other.

turned out it was a fat pink cord with a silver horizontal stripe... not sure what the pin number is... I'll look at it later. I found the VSS, reverse is connected, test drive was a bit clunky - I'm getting some invalid parking brake statement... I'll do some searching of avic411.

Thanks for your help.

I'm installing my Avic-z1 in a 2007 Toyota Highlander Hybrid, Limited model. So far everything works but the speed sense cable. I've read a dozen threads about my year and others close to it but none have worked for me yet. I've tried this one for the 2006:

"Speed Sense is the light blue wire in the HVC (Hybrid Vehicle Control) ECU, in the top plug, in pin 24. The HVC ECU is behind the glove box of course, and the module to the left"

And this one for the 06/07 : Speed Sense is the light blue wire in the HVC (Hybrid Vehicle Control) ECU, in the top plug, in pin 24. The HVC ECU is behind the glove box of course, and the module to the left

MikeAny other ideas or suggestions please?

I know this is an old thread but just want to confirm that the VSS wire is in fact the yellow wire, pin 17, second plug down. Just installed an AVIC-X940-BT in a 2005 Toyota Highlander 3.3L, and on this particular unit as similar series models the VSS connection aids in eco fuel efficiencies, and accuracy of GPS.

To gain access it’s best to remove the glovebox for proper splicing. To remove push two bushings inward at the sides and pull forward, then unscrew softclose wire behind the glovebox on the right, lastly remove two black plastic pushpins along the hinge using needle nose pliers. Glovebox comes completely out to expose the ECM. 

Oh yeah, if you haven’t it’s a good time to change the carbon filter that sits behind the glovebox. ; ^ )
