x940bt wiring help
 

First time doing some of this wiring and wanted some help / reassurance.
These are the wires that i havent accounted for yet from the x940bt harness.

These are the wires I have left on my Metra harness adapter:

and my LSAAB antenna adapter:

So i wanted to know if i am suppose to connect the x940bt blue/white to the antenna adapters blue wire?
And where do I attach the violet/white wire and the pink wire? do i need to connect these 2 wires at all?

Also should i attach the black ground wire to the black ground wire on the toyota harness or should i ground it to the cars metal body?

Any help is great, thanks!

yep blue goes with blue. i didn't attach the pink or violet. i'm sure you can if you really wanted to, but you don't need it for your unit to function correctly. it may not perform all the extra features, but if you don't need/use them then it doesn't matter anyway. for the black wire i went ahead and wired it to the harness, although i'm sure if you wired it to the chassis of the car that that would be fine as well.

The antenna adapter blue should connect to the Metra vehicle harness adapter blue (blue to blue). The head unit will send a power antenna signal as needed to the vehicle harness.

The 940 blue/white would be used to send a 12v "on" signal to whatever you want when the head unit is turned on, ideally, amps (amp remote). If the car has an OEM amp (or if you've installed an amp), it may need to be connected, otherwise leave it be (fold it over and heat shrink it to prevent a short).

The 940 pink wire (I don't think) is necessary... I've never installed an aftermarket nav unit. The 940 violet "reverse" wire would look for a signal from the car to activate the rear camera input on the 940 screen. Unless you've installed a camera, this can also be heatshrunk/ignored. The 940 pink speed sensor, not sure of you need it or not...

All grounds should be connected to chassis metal somehow, or at least the vehicle harness ground at minimum.

Thanks!

So the idea is that I should be connecting the Antenna adapter blue wire to the Metra toyota harness blue wire, and leave the the new headunits' x940bt blue/white wire alone.

Isn't that a little weird then? the blue wire sends a signal coming from the car then goes through the antenna adapter into the toyota harness and back into the car? sorry for some of my ignorance.

No. You're going to have a total of three blue wires soldered together.

Is there another blue wire from the 940? The blue/white is for amp remote, not power antenna. Now I'm a bit confused..

nope.
Heres a description of the blue/white lead from the manual

some headunits dont have a seperate antenna wire so you can use the remote wire which does the same thing. sends a + signal when the headunit is ON.

so YES you can use blue/white for the antenna wire. check the metra harness and see if there is an actual pinout for the blue wire on the OE harness side where the blue wire of the metra harness connects to. if there isn't you dont need to connect that one. if there is you will be soldering/crimping 2 wires together to the pioneer blue/white remote wire.

i hope that isn't too confusing.

No that makes perfect sense, thanks. I've never had to connect the remote wire to the antenna in the dozens of installs I've done. Learning!

yeah a lot of the newer cars have amplified antenna's so you will be seeing alot of that now.

Thanks!
So if there is, i'll be doing what phanguy and you have said soldering 3 wires together. Blue Blue and bluewhite
Thanks everyone for the help!
