2008 lexus is350 possibly push to start

I used the XK-05  (IM-05) and I did not have to go to the passenger side at all. All my connections were made at or near the start button and/or drvr side fusebox. Your TX and RX lines are at the push to start switch too!thetopinstaller

OK, job's done. Apparently the customer needs a refresher course on the Latin alphabet, because this turned out to be an RX350 with a conventional key. It was a 2008 though. For what it's worth I did get some video, and also tested the new firmware for the XK05 (PKTI firmware). Worked as it was supposed to and as I think I mentioned earlier it connects to the RX and TX at the immobilizer ring, not the stupid IMO/IMI at the ECM.

Fine, job done and aren't they a doddle physically? My big question? Did you go directly to the lock wires in the driver's door to give you lock and comfort close or did you have to use the isolating relay and diodes?

Actually wasn't so bad. Ended up going to the door module for lock/unlock, just the straight (-) trigger from the key cylinder. About as easy as running wires into a door gets - 2 molex plugs with all the door wires are easily accessible in the DKP junction block, and can be easily disconnected and the boot pulled out.C Renner's Auto Electronix

So was I right about not needing the relay and diodes for the locks?

Absolutely right, Howie. Didn't need a single additional relay for anything!C Renner's Auto Electronix
