My project car doesn't have the resistor relay so I need to find a way to activate the fuel pump.

First. I don't care about "fuel economy". I want 12v no matter what when the circuit is activated.

I was looking at the FSM and the NA VS TII is the same up to the point of that relay.
I'm not understanding the actual plugs though

So on the circular plug up front.
There are two Blue wires and then two Blue/Red (Power?)
Then a Black/While (Ground?)
Then Green/Red (Low voltage signal?)

On the Hatch Plug there is Black and Blue(other two don't matter for this)
Blue is power
BLack is ground.

----------------------
So
What are the Blue and Blue/Red wires on the front harness? power? Why a pair and not just one power wire?



Anyone care to give me the easy answer as to which ones I need to loop together?

---------------------
Oh, I am going to use this wire as a signal for a local relay to my rear mounted battery. So this wire won't even feed the real power to the pump. I just want to keep the emergency shut off/running characteristics.

HAILERS

Jumper either of the Blue/Red to either of the Blue and your set.

Forget GR and BW. Not players.

I was looking at the FSM again and it makes sense now.
They split it into two wires. One goes through the resistor while the other is unrestricted but has a switch on it.
So it just switches between thw two paths dependant on the green wire signal.

Kind of a waste of wire to keep them as seperate lines leaving the resistor setup. I don't see why they couldn't have made it one return line. Oh well.

I'll just connect each blue to a blue/red any way.

Thanks

So basically u just put the 2 blues together left the plug in relay ?

Anyone know how to bypass the fuel pump relay under dashboard on a 1987 mazda rx7 turboII s4 COMPLETELY BYPASS IF POSSIBLE
