Another SR wiring issue....

[MistaZ31turbo]

Sup everyone...well ive thrown an bk top s13 sr into my 95 sx. I was following frsport.com (i think thats them) and pretty much wired up everything like they had but somewhere i missed something because the black/yellow wire (fuel pump signal from KA "F3" plug) isnt hooked to anything and Im not sure where it goes. Yeah you guessed it....no pump prime. So does anyone have any idea where I hook this wire up to? Also there is two relays in one of their pictures and my car only have one (ECU Relay). That may be because i am swapping this into a automatic chassis, not sure. Is there a way the car will start up without it or do I need to hard wire another one in? Thanks

Cmon guys...all of the knowledge in this forum and not one piece of help?? Where does the Black/Yellow wire go from the M63 connector?

You might want to wait more than 2 hours from a post made near midnight before you jump on the "How come no one replied yet???" wagon.

S14 SR service manual. Go to page 294, and that should be the fuel pump wiring you're looking for.

Mating an S13 SR into an S14 chassis is a bit more difficult than the simple rewiring job on an S13 SR into an S13, but it's been done before. The S14's dash plug serves as the primary plug for the EFI harness, but on the S13, a lot of those wires go through the two plugs by the battery tray. You'll need to move a bunch of those back over to the dash side of the harness. My suggestion is to take the EC & EL section of the SR manual and the USDM 240SX manual, and make sure you mate up the wires from the SR harness to the S14 dash plug. Also, if you use the USDM S13 DOHC manual, most of those wires will match up with the S13 harness (aside from the way the ignition wiring is done, they're practically identical).

If it's too much for you to handle, you should consider getting a conversion harness.
