Installation:

1. Select a mounting location. This sender will

perform optimally when mounted with a ‘clear line

of sight’ to the sky, i.e.: not blocked by a roofline

or other steel structure. Other locations may work,

depending on your vehicles characteristics. This

sender has been designed with a watertight

enclosure and may be mounted in an exterior

location, if required.

2. Wire the GPS Speed Sender as follows

Note: +12V can be constant (ie: to the battery) or

switched.

 +12V constant will allow the GPS sender to

maintain constant connection to the GPS

satellites and allow for immediate speed signal

at vehicle start. Battery consumption is

comparable to that of a radio’s clock.

 +12V switched will not draw any power when

the vehicle is shut down, but will require 35-60

seconds for the sender to connect to the GPS

satellites when power is switched on.
