I am just simply looking for the alarm/remote start wiring codes for a 03 Toyota Highlander. I also want to know about any special place to mount a prox. sensor. I was thinkin center consol that's where I have done them before and have had no problems. All opinions are welcomed thx.

Notes:	This vehicle is equipped with a Transponder Anti-Theft security system. Use Universal Alarm Bypass Module part # 2x402 where X can be any number. The Engine Control Module (ECM) is behind the glove box, it is the module to the left of the glove box. ** The key sense wire will measure 12 volts all the time till you place the key inside the ignition switch and the key sense wire will ground. Connect the WHITE/ black wire from the unit (ignition 3) to the wire and that will disarm the OEM factory alarm.

Well I gave it a shot and well 1/2 of the wires and their locations are incorrect and the relay set-up from the notes was incorrect, U use a pink (unlock) and a pnk/blu (lock), and U aslo have to tap all the door triggers for each door seperately. Plus the factory disarm wire was nowhere to be found, I have been on this for 2 days and I just now got going on the remote start end of the install. I appreciated the thought and your help boomer, but this information was not helpful enough. But thx again
