Ok, so i'm literally right around the corner to starting my RB swap.. but my incompetence has stalled my start up.

So story is I was feeding my wiring harness through the firewall, and unplugged the two green relays so it would fit through the firewall hole. Yea, all went well... but now i cant find those stupid relays. I turned my garage upside down for 3 hours trying to remember or come across where i had put those RELAYS!

Can anyone tell me what relays those are? If i can order some new ones? or if anyone has some extras laying around?!? I searched through the FSM 2wice over trying to find a wiring diagram... NOTHING.

Yes i'm desperate... please help?

Any green nissan relay will work or you can go to advance and order them, they are like $5-6 a piece.

I had a similar problem, except my injectors weren't getting switched power because the ecu wasn't triggering the relay. So i just jumped the main thick wires so they had power all the time. That was after I bought 2 new relays and still had a problem with no power to my injectors.

Good news, found the relays... bad news.. still doesnt start. I'm thinking i have the wrong "white wire" that goes into the ka fuse box. The one thats supposed to match up with the White/purple RB wire... Where exactly is that white wire??

Wip out that multi meter.IIRC, it's any wire that gives 12v in the "start" and "on" position but 0v in the off.
