How to manually wire a toyota fuel relay
This relay came out of a 92 4runner v6, and to make a long story short i need to wire it manually. Does anyone know how to identify the pins?

looking at the second picture. if ur not gonna use the relay. i wanna say you jump the to top right pins on the fuse box. i looked on alldatapro and the fuel pump relay shows up as a circuit opening relay but it looks just like what you posted

If it does not show you on the relay some Toyota ones do others don`t.
Should be pretty easy to figure out with a multimeter the coil should have a resistance of between 40 to 60 ohms
The contacts should be open and read infinity if it is a good relay you are starting with.
Pins 1and 2 are the contacts
#4 is a coil coming from the air flow meter
#3 comes from the ignition switch
#6 goes to ground
pins 2and 3 are at the top with the relay held that way # 2 to the left
This has 2 coils that pull in at different times one at start and the other when it sees air flow via the air flow meter
Just what are you trying to do?

Hmm. Awsome info. I'd like to hook the pump up to the ignition swith's on position.
I had this relay hanging around from a rig I parted out. So I figured I'd use it if I can.
If I can't I don't mind buying a generic one, but what amperage should I look for?

The fuel pump won't come on when I jump the +B and FP in the DLC1 port. The +B isn't even getting power. When I put power to the FP it fires up just fine. I have checked the ECU fuse and it seems to be working. I don't know what else it could be.
