Twelvoltz, sorry about this but if you look very carefully, on the audio side battery and acc are wrong way round, also unlock wire might be blue/red, if it follows E46 3 series, trunk feed should be in driver's floor loom and it's brown/white neg, NB blocking diodes required on trunk light(s), place on red/yellow power feeds, bar towards light unit, trunk release if there is one is grey/green +  Brake light DO NOT USE SWITCH IT'S CAN!! Blue/black and green/black in floor looms both sides carry 12v+ to the brake lights, also tach is a thin black lead on the OBD II socket under dash. Lastly as a convenience point, all of these except one of the brake light feeds are in the driver's floor loom, even the lock/unlocks come out of the driver's door and join this loom, thus everything can be centered around driver under dash area. Hood switch if factory installed is purple/green. Extend lock pulse to close windows and roof, use a DEI 556U for the bypass and place only the "valet" or "purse" key in it.

Sorry, you can NOT post a reply.
