Hi all,

Just new to this forum, but looks great so far!!! I have just rebuilt my 1994 RX7 and upgraded a number of bits. I am currently trying to figure out how to wire my secondary fuel pump. I have installed a 2litre surge tank in the boot which is feed by the factory pump. From the surge tank, I have used a 600hp Bosch fuel pump to pump fuel from the surge tank through to the fuel rails. On the fuel rails I have used 4x 850cc injectors, this then feeds a Malpassi fuel pressure regulator set at 45PSI static, this then returns to the surge tank and then to the main fuel tank. I have installed a second fuel pump relay, but I am trying to decide the best wire to use as my trigger for the relay. I would like to tie this into the trigger wire used on the factory fuel pump relay, but I don't know if this is the best place, any ideas?????
