hey guys, my front wipers dont work after doing a rb25 conversion. i read thru predators tutorial but i still cant manage to get them working. ive tried exactly what he listed in his tut :rofl:

can someone guide me in the right direction plz? :D

cheers

Edited by whyte

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?

    • This is a real nostalgia trip for me, I mean SK Bilsteins? I ran those lol Good times.  Good work Duncan, it's not an easy job in many respects. I'm sure the family appreciates it. 
    • It's not a dumb question. I was circling this idea myself. User error is always possible!
    • Nope. The seal is in the drive. A new cable would just fill up and continue to convey oil to the speedo head. To check if this is what is happening, take the cluster out, dismantle the speedo and have a look. You probably don't even have to dismantle it. If there is oil coming up the cable, the drive into the speedo will be grossly greasy. I had to manually (and delicately) clean the gunk out of my speedo.
    • Thanks for the quick response mate, and I agree Nismo 555s, Z32 and high flow 2871 in OP6 housing (run by PowerFC) would all be "period correct" and should be a simple, reliable and reasonably quick track car.
    • It is normal for a speedo to read 0-10% high (unfortunately), intended by manufacturers and ADRs (although not in this case) to ensure your speedo does not read low if your tyres are worn. Speaking of which, what size tyres do you have on the rear, and what does they tyre placard say you should have? you can use this https://tiresize.com/calculator/ to determine what % difference that is causing Personally, when I buy tyres for a car I buy a size that will bring the speedo back to being more accurate; it if it reads 5% high I buy tyres that are 5% larger diameter. If you had an electronic speed sender like R33 onwards, the other option is to add a speedo adjuster but that won't work in R32. Finally, you  might be able to find a different sized gear for the speedo sender but that will be limited to what already exists (and I don't know what sizes do)
