Hi there. I am looking for an EWD / wiring harness diagram for the T1814 Pioneer radio that was installed in 2010 xB and particularly the steering control wiring details.
If anyone has the EWD I would also love to see a visual of the male or female harness plug so I can try to source a male plug.

I am installing this radio into an old Lexus and looking to see if I can re-purpose the obsolete analog phone controls on the Lexus steering wheel to control some functionality on this deck.

many thanks

if anyone by chance knows the resistors on the switch, i'd be grateful for the knowledge.

 

I have a spare xB wheel with switches in my garage; I'll try to remember to grab some measurements later this evening. If you don't hear back from me by tonight, respond to the thread (I'll get an email notification) to remind me.

 

Hey Paul, would you be willing to sell with those controls? I fubared mine this last time while I was changing the LEDs.

 

Measuring the actual switch pad resistance gives me 100k on each. The circuit is more complex, but you should be able to just recreate it per the diagram with 100k resistors.

@Greg, I have the loose PCB as pictured; the surface mount LED is a little melted but I believe it still works (I was going to swap it and gave up when I realized it was hard to remove without melting things). The harness/plug is chopped off so you'll have to solder your original plug onto it. If you want it just PM me your shipping address and I'll drop it in the mail.

If you need more pieces let me know - I have the full switch housing somewhere around here as well. I actually have a ton of spare xB parts that I've come close to throwing away more than once; I should probably post a freebie thread in the classifieds section.

 

Perfect! Thanks Paul. I'll take both the PCB and the housing if you can find it. I've swapped the LED a few time and just wasn't paying attention this last time and burned the board. I'll PM you my shipping address.

 

awesome. many thanks.

now to see if i have any room to reproduce that.
