Well I just looked for behind the glove box which I removed completely it but there isn't, so I guess the guy that installed the Haltech EFI, had to removed and is missing now. It seems I will have to make my own relay connection but simple energizing the fuel pump with the key switch in On position and another hidden switch that allows to shut the pump off while main switch is On, it also can be used to prevent to be stolen.
Any other good idea?
Thanks.
