Just ordered a Z110BT and i'm trying to plan out my installation. This will be my first time installing a headunit, so I need all the help I can get! Does anyone know where I can find the VSS and Reverse wires on the 2002 Acura RSX base? I keep hearing about these wires, but what do I have to do with them?

The VSS will be one of two wires, each depending on whether you drive a manual or automatic.

Manual: Connector A on the ECM, pin 18 (White/Green)

Automatic: Connector E on the PCM, pin 25 (Blue/White)

Both of these modules are behind the glove box.

As for the reverse lead, I think it only matters to hook it up if you are planning on using a reverse camera. There are a couple different ways to do it, some guys find a reverse wire on the ECM, others just hook into the backup lights. Basically whatever wire sends a pulse when the vehicle is in reverse will work.

See my 4runner thread for pics on how to tap the leads into your wires: viewtopic.php?f=25&t=15301
