2003 toyota sienna transponder bypass

And yes you need the 555U. Actually it would be easier if you would just wrap some thin stranded wire around the key, Put it through a relay (87a and 30) and then 5 or 6 times around the key cylinder. Connect the relay coil to turn on with ground when running on the remote starter. Works every time especially on Siennas and you save a couple of bucks."

Can somebody explain how to do this more detailed, like wich wire goes to 85, 86, 87 connectors?

Thank you....
