Ok so my rb20det harness was cut at the two green relays right next to the ecu.

I know one is Fuel pump and the other is Eccs i found the 4 wires to each but just trying to figure out which location of the wires on each relay.

Attached below is the best i could find through the FSM.

Somebody explain to me what is going on. 104 27 and 40 are understood.

I will try to get a picture of the wires that are supposed to be relayed.

This should be the last thing cockblocking the Rb from starting.

Any help appreciated.

Any help?

Run power from pump to battery or you could always jump the fuel pump relay and ground out the fuel pump wire from ecu (black/pink on rb25) that way it will constantly run haha if you really wanted it to start

One question though. The thicker white wire would follow 3 on the bottom relay?
