post the tutorial link please?

is there a blown fuse or something? is the motor getting power? etc

[dori34]

its in the tutorial FAQ section (Search for rb25 conversion), i cant post links when at work cause im using a proxy website.

i think theres another plug somewhere in the r32 body loom that it has to be bridged to but i dunno which one it is.

no blown fuses, ive double checked them all.

hey eug, here it is, copy & pasted

Wiring

Wiring is pretty straight forward if you have the correct diagrams and ecu pin outs. I'd recommend using the RB25 loom and ECU, which is what I used. This a) allows easy engineering to meet polution standards b) Allows you to run the cheaper and more readily available RB25 powerFC. Once you can get the stock ECU working fine, just drop in the PowerFc and it should work right away.

I won't go through the whole lot here, but a few things to note.

1. Grey wire near the main engine bay plug is your 12v constant injector feed. Make sure this is hooked up to a 12v line. Without this the car won't start.

2. It's not a bad idea to splice in your original engine bay resistor (passenger strut tower, silver block thing) from the rb20 loom back through the firewall and to the thick black and white wires of the r32 body loom. This provides backup ground to your fuel pump incase you lose the grounding in the boot area. It will work without it, but is a valuable safety measure which is worth keeping if you value the engine.

3. Use the O2 sensor from an RB25. I believe the R32 one is different. Effects fuel economy

4. To get the wipers working, you can use the r33 loom plug as a direct fit into your wiper.

There is another plug nearby which looks similar. You'll need to connect the orange in this plug as well or your wipers won't turn off once turned on until IGN is turned off Cut the orange up near the plug, and run a wire to this through the firewall, and this connects to one of the wider R32 body loom plugs. There is like a thick orange and a thick green next to each other. Connect this to the orange. This turns the wipers off when you whack the wiper switch back to "off". Took a while to work this out.

You also need to attach 12v IGN source to blue w/ red stripe on that plug. Hook the black with silver blotches to GND (or chasis).

The rest of the r33 plug is 'spare' and the other wires can be left disconnected down near the r33 ecu part of the loom as well.. On the R33 it connects to a brown junction box on the passenger side...but on the R32, this is on the driver side and can stay there.

difficult without actually seeing them. wiring is a pet hate of mine, just make sure you trace everything and label them.

have you done everything he's mentioned in his post?

he says that the 33 loom plugs straight in into the wipers - i take it you've done that?

the wire which you mention needs to be bridged is on a nearby plug, the orange wire needs to be connected - have you done that?

is it getting power?

i managed to get it working,

only 1 thing that predator said to do was right (bridge the orange wire) everything else didnt work, had to do it another way with the helps of simona31
