Hello everyone, BEFORE I START PLEASE ASK QUESTIONS IF YOU HAVE THEM For a few months now I have been thinking about changing the controls on my old Triptronic steering wheel to audio controls and this weekend I actually sat down and did it. I must say that it was quite the bitch, and I went through many different designs before I had the final version, and this final version, in my opinion, is the best way of doing it. This guide isn't a step-by-step walkthrough unfortunately because I have already installed the system into the car, I am writing this in retrospection so other people can also do this on their cars, as I have seen it asked about many times. First I'm going to cover other designs that I have seen which are either stupid, needlessly complex or just wont work as expected FAILED DESIGNS Using a 4-way transmitter and reciever (As seen in THIS video) (Would work but needlessly complex and many POF) Wiring resistors inline and running wire from steering wheel back to head unit (A steering wheel rotates //2short) Using a pre-existing PCB and wiring it in on the "dash-side" of the steering column (Ribbon cable in wheel boss wouldn't support enough inputs) OK, Now that that is out of the way. We get onto the good stuff. Below is 3 things. REFER TO THESE INCASE OF UNSURE OR COMMENT 1. A video of the finished product AND a talkthrough of how it is all wired (I rambled a bit) 2. A rough wiring diagram for reference 3. The notes of which wires are connected to what and the pin layout of the PCB. ALL WIRES MAY NOT BE 100% REPRESENTATIVE OF YOUR CAR (ie. Different Colour or Pin) SO PLEASE CHECK WITH A CONTINUITY TESTER FIRST WHAT YOU NEED Steering Wheel Control Harness (Most often comes with your stereo as a 3.5mm jack) Universal Wired Steering Wheel Controller (What I used) (I MIGHT SELL PEOPLE JUST PCB's WITH THE WIRES PRE SOLDERED ECT IF YOU WANT ONE PM ME) Soldering gear and experience Plenty of wire OPTIONAL: Desolderer (Expensive and doesnt need to be used but makes light work of desoldering PCB) HOW YOU DO IT ALL WIRE COLOURS THAT ARE UNDERLINED ARE THE STOCK WIRES, ALL IN ITALICS ARE THE WIRES I ADDED PLEASE TEST THE CONTROLLER AND 3.5MM JACK IN YOUR HEADUNIT BEFORE INSTALLING ALL COLOURS AND PINS MIGHT BE DIFFERENT IN YOUR CAR SO PLEASE PLEASE PLEASE CHECK BEFORE YOUR CUT ANYTHING Prepare the PCB Take apart your Universal SWC and remove the PCB. It should have a number of tactile switches on it and a power cable Test and notate which pins are Ground and which pins the actuation pin is. (This can be done with a continuity tester) In my case the whole board shared a common ground between all switches Desolder all of the tactile switches Solder new wires to the actuation pin for each switch Solder a wire to the common ground for the board. You should now have 5 wires soldered to your board (4 actuation + 1 ground), as well as the 2 original power cables IF YOU DONT HAVE THE TOOLS OR SKILL FOR THIS I MIGHT SELL A PRE-SOLDERED PCB FOR THOSE WHO WANT ONE (PM ME IF INTERESTED) DISCONNECT THE BATTERY!! Remove the Airbag Remove your key surround, upper column cover and lower column cover to gain access to the steering column (5 Phillips head screws in Lower cover) On either side of the steering wheel there is a plastic cover which covers a Torx Head Screw holding in the airbag. Remove both covers and screws Disconnect both plugs on either side of the steering wheel behind the previously removed covers. The airbag should be able to be pulled out now Prepare the Switches With the airbag removed you should be able to see the wires for the switch relay. Find where the two switches combine into a single output in the centre of the steering wheel and cut just before here, so that the switch wires are seperated. Solder the "COMMON GROUND" from your PCB to the YELLOW wires from each switch. Solder the "UP" from your PCB to the GREEN wire (One Side Only) Solder the "Down" from your PCB to the BLUE wire (Same Side) On the other side, "Next" -> Green // "Back" -> Blue Connect PCB to Loom On the passenger side of the steering wheel there is a plug, make sure it is disconnected. On the upper plug, follow the wires back to the cut you made earlier. Clean up and hijack the BLUE and YELLOW wires. Connect the POSITIVE wire from the output of the PCB to the BLUE wire, and the GROUND wire to the YELLOW wire Tap Wheel Harness On the back side of the of steering wheel boss there is a cable with a yellow plug (the wire itself is also probably covered in yellow tape) which runs back into the dash. Locate this plug and strip back whatever is covering Cut the 2 GREEN wires on the PASSENGER SIDE of the plug (Make sure to leave enough wire to solder to) Solder a POSITIVE wire to the INNER wire that you cut (INNER to the centre of the plug) (Make sure its long enough to run to the back of the stereo) Solder a NEGATIVE wire to the OUTER wire that you cut (OUTER to the centre of the plug) Connect Harness to Audio Jack Make sure you have enough wire to reach the back of your stereo Solder the POSITIVE wire to the "INPUT1" wire on the SWC audio jack Solder the NEGATIVE wire to the "GROUND" wire on the SWC audio jack Plug controller jack into Reconnect battery and test if working If working DISCONNECT BATTERY!!! Cable manage and protect your PCB with whatever you can (I used heatshrink) Reassemble airbag (remember to reconnect plugs and TORX screws) Reassemble steering column If not working Check your wiring against mine in the diagrams and the handwritten sheet (The handwritten sheet is the notes I took on the day so they are 100% correct for my install) Use a continuity tester and check wiring if able Write a comment and hopefully I will be able to help ENJOY THE AUDIO CONTROLS Conclusion If you need help with anything dont be afraid to comment and I'll help out the best I can. I have seen tons of people asking about how to do this for a number of years now but I believe this is the first tutorial. I posted a couple videos to facebook of it and there seems to be alot of people who are interested, however, I believe that people think its a lot less time-consuming of a job than it actually is.

Hey guys, I'm back with another tutorial that I made (thanks to isolation). This is on a how to swap the RB25 bottom end to a RB30 bottom end with a 25 head in a R34 (R33s and R32 should be kinda similar i think) that I did last year. I had to split the tutorial into 3 parts (each part is like 15mins). It starts with preping the RB30 block, to taking out the RB25, and then putting in the RB30/25 and starting it. The reason why I did an RB30 swap was not because of an upgrade but because my RB25 was showing up bad results on the comp tests and there were cheap RB30s going around (I actually made money out of selling parts from the RB30 that I didn't need lol). The goal for this car is only to be a daily responsive streeter on pump fuel (won't ever take it to the track). It's my first time ever doing something like this (I had no help, did this on my own), so take it as a guide line. If I were to do this again, I would definitely use a proper engine crane and take the whole engine out including the gearbox next time, but yeah... this was a real poor mans job and it got the job done and I've been driving this RB30/25DET Neo everyday to and from work as my daily and I've never had a problem with it (have been clocking 5000+ Kms on it as of 10/4/2020). Here's the videos: Part 1: Part 2: Part 3: I'm really happy with the outcome. Considering I knew nothing about RBs or any engine before I bought this R34. I learnt everything from researching (a shit load) on these forums, so thanks SAU, here's me giving back. The car ended up making 323.8 HP on the dyno with my OP6 highflow turbo which is a bit too small for this engine. So I will go with a bigger one in the near future. List of mods on my car previously that I brought over to the RB30 swap: HyperGear G2 RB25DET OP6 highflow turbo with ballbearing 3" turbo back exhaust 100mm thick FMIC Splitfire coil packs Xspurt 525cc injectors HDI EBC Nistune ECU Z32 AFM Walbro 255lph fuel pump (hard wire mod) 98RON Exedy HD clutch External oil cooler Koyorad all aluminum radiator Just something to add here on the side if anyone was interested (kinda like a build page, but I might as well put it here). This was my whole budget explained: So the total amount that I spent on this build/recon/swap was $3415. I bought a complete RB30 engine (without the box) for $150. Apparently this engine was used in a TAFE course for mechanic students to practise timing stuff on, so the pisons had heaps of screw driver marks on. A recon was in the picture anyways because I want this engine to last for ages. So I only wanted to keep the block, crank and rods. I sold everything els (head, alternator, ecu ect) for $240. That's already a profit of $90 lol! The reconditioning of the RB30 block and RB25 head was the most expensive out of the whole budget costing $1420. The recon from Harris Engines in Perth: $400 - Bore and torque plate hone $190 - Face block $180 - Machine and fit crank collar $90 - Acid bath $90 - Face/deck RB25 head $50 - Acid bath head $90 - Face flywheel $150 - Fitment of pistons to rods $180 - Balance rotating assembly All other things: $270 - 1mm oversized Hypatec RB30ET set of pistons + Hastings Rings $253.45 - RB25 ARP Head stud kit (202-4301) from wolf racing $261.25 - RB25DET Neo genuine nissan gasket kit $106.49 - RB30 ACL race main STD bearing set $88 - RB30 ACL race conrod STD bearing set $30 - RB30 small end rod bushes/bearing set $99 - RB crank collar from Lewis Engines $38.75 - RB oil restrictors (one 1.5mm and one blank one) $38 - RB30 brass welsh plugs $13.71 - RB spigot bush $38.98 - RB genuine nissan timing belt fastner kit $41.5 - genuine nissan thermostat $78.14 - Genuine nissan R34 pull type thrust bearing $110.5 - Genuine nissan RB25 exhaust manifold fastner kit $43.2 - Dayco 94407 (T866) timing belt $72.11 - Mamba RB30/25 turbo water braided line kit $81.59 - Braided -4AN hose + fittings for the external VTC feed from Enzed $330 - Dyno tuned car by C-Red in Perth All of the labour except for the recon and tuning was done by me.

I got my exhaust manifold resurfaced so I thought I'd make a video of the removal process. Let me know if it's good or sh#t. I'm no mechanic or expert in RB's (or any motors), I just use google and use my mechanical mind... Tutorial was done on my 1998 R34 GTT RB25Det Neo (Hypergear Highflow turbo with stock exhaust manifold).
