Hello all,

I went to install my VAIS Tech SLI this afternoon, but none of my Y adapter connectors seem to match with my 2007 GS with Nav and ML. Just to make sure I wasn’t going too insane I had my father look at it since I’m on vacation at my parent’s house and figured someone with a PhD in Electrical Engineering would know ...unfortunately he agreed also. One connector connects to the other SLI connector and the others are way off on pin counts. Would someone that has not installed their SLI yet be kind enough to take a quick picture of the end connectors of the Y adapter before I return the cable for the proper version.

Thanks all!

 

Hi Dan,

I don't know if this helps at all, but when I installed my SLI the picture in the manual that shows the Y adapter and which connectors are suppose to go where in the Head unit was not accurate for me. I spend 15-20 minutes going crazy cause the diagram in the manual didn't acuratley represent the correct way to hook up the unit. Once I found the right Y connector plug that plugged into the head unit, everything else pretty much fit into place.

Again, it just was acurate with what the VAIS tech manual showed. Whomever taped up the Y connector at SLI did it wrong (at least for my connector).

Hope that helps.

What's tricky is that one connector on the Y cable plugs into the "extension" cable which then plugs into the SoundLinQ. So if you're trying to figure out which connector on the Y cable plugs into the SLx, the answer is none of the three.

Thanks gang,

I've tried every possible connection and connector combo, but only one fits in any way, shape or form. I've since put the car back together as I have to travel to Charlotte tomorrow morning and didn't want to run into any problems putting things back together.

When I got the SLI I thought the Y adapter had fewer pins than what I remembered on the Nav, and once I got the Nav out that was definitely the case. I'll ping VAIS Tech later, but would still like to see pictures of somone else's SLI Y adapter for a 2007 GS with Nav & ML.

Dan
the y adapter does not plug into the harness that the nav has, it goes on the radio unit that connects at a different spot.

 

Yes, the SLI manual is a bit off in their pic. The 2 harnesses supplied in my SLI kit plugged into each other. Then one end went into the SLI metal box, and the other 2 plugs were used for the connection of the OEM radio plug into the SLI plug and of course plugging the new SLI clip into the back of the radio.

On my 2007 with NAV and ML, the connector on the back of the Lexus radio was very low and closest to the passenger side of the cabin. It is not one of the "top" row of plugs on the back of the radio that you might first suspect... none of those even comes close to matching the right size. hth

 

Thanks folks, I'll give it a try tomorrow now that I'm back at home.

 

Okay any ideas? There is no way they will connect.

First picture is of the connectors from the car:


Second picture is SLI on top with Nav below. Three on the left are the Y adapter and the two on the right are supposed to come from the SLI unit.

(poor quality but you get the idea, every other picture washed out)

The connectors in the top pic are in the order that they plug into the nav directly.

 

Those connectors are from the top unit in the stack. The one you need is actually way down at the bottom, like behind the cassette deck area. There's another row of three connectors down there. The one in the middle is your man. I just put the VIAS SLI in tonight, and I was confused the same.
