I have gps tracker device and has features to engine off and on by smartphone..I have two green wire on my relay and need to connect with fuel pump wire ...I am not sure where is located and what is the colour?. Can anyone help help me to find out?

 

There are actually two fuel pumps (the conventional one in the fuel tank and a high pressure fuel pump located under the intake manifold). For the fuel cut-off, you'll want to use the power wire for the conventional fuel pump.

It is a purple wire and runs to a connector that plugs into the back of the under-hood Auxiliary Fuse Box. The fuel pump power wire is at terminal no. 36.
