my book does not tell me annything about having a open circut relay inbetween the
main relay and the fuel pump except for the wiring dyagram I would have never known it to exist.I had a small kill switch accadent so I by-passed both systems.I need to know where the open circut relay is by my feul pump wirring in the back or
up front by the steering collum 1978 rx7

 

I assume you mean an 87 RX7?

If so it is up front almost on top of the steering column if not just right to the right side of it. It is a little black box if I remember correctly.
