There are 3 connections on the unit, one main connector block, labelled "Conn1", and two GPS antenna connections, labeled "GPS1 Antenna" and "GPS2 Antenna" respectively. The main connector block, Conn1, should be connected to the large connector on the supplied cable loom. The pin assignments for Conn1 are illustrated in Figure 1, which shows the male output on the BRAKEBOX unit. The other connectors on the loom are all individually labeled. The positive wire on the power lead has a grey or white stripe.
A 3.3V active GPS antenna must be connected to "GPS1 Antenna". GPS2 is not used on the BRAKEBOX.
"WARNING": To avoid any possible damage to the car paintwork, please take care when mounting magnetic GPS antennas. In particular make sure that there are no dust or grit under the antenna. In some cases it maybe required to add additional protection to the paintwork prior to mounting the antenna to avoid damage.
