ok everyone says its easy but i cant get my fuel pump to turn on. Can someone please walk me through it and let me know where exactly you should put the relay and which wire should go where?? Im using a 5 prong but no matter how long i stare at the wire diagrams i cant make sense of any of it.

I have a 3rd gen 3sgte in my 96 gt, please i know many have done this but i cant find the info i need.

Hey guys Sorry to bring up an old post but I'm stumped on this and this pic of the fuel pump is pretty good quality for reference. I'm in the same boat with a gen 3 3sgte going into a 96 gt celica. My motor did not come with the fuel pump relay or ic relay. I'm keeping the front mount I currently have so I will throw a resistor to avoid the 54 code. I picked up a 5 pin Bosch style relay and have been studying the diagrams but I I just wanted be sure I'm wiring the relay correctly. I have identified the 4 wires within ea1 3 sgte engine harness plug. Relay of course has 30 85 86 87 and 87a. Does the below wire configuration to the relay look correct. The only thing I am hung up on is the blue and orange wire but to me that would be a positive 12v and the switched ground connecting together.

Blue w/ orange stripe (What relay spot does this go to?)
87a Blue w/ black stripe
87 = Blue w/ white stripe
85 = Green w/ red stripe
30 = ?
86 = ?

Any help would greatly be appreciated.

Here's how it should be :

87a = Blue w/ black stripe
87 = Blue w/ white stripe
85 = Green w/ red stripe
86 = Blue w/ orange stripe
30 = Blue w/ orange stripe
