Oh btw, the climate needs a separate outside temp to work. You need a mk4 one as the Corrado one doesn't work with the mk4 climate. You'll in effect end up with 2 outside temp switches, one for the instrument cluster and one for the climate.

You have to be careful not to rely on cable colours, they change from time to time. The heater box is a lot bigger than the stock corrado item and as such you can't fit the glove box back in, it's too long. That's why you need to cut and shut 2.5 inches out of the middle. I'll read over your write up later this evening and see how it sounds!

That's giving me naughty thoughts!

In other news today! Fitted the polo 02j hybrid gear change! Feels soo much better than stock! Also cut my glove box down so that it fits properly with the new heater box. For anyone who wants to know, you need to shorten the length by 2.5 inches to leave 5mm of clearance at the back. Still leaves a healthy size space!

Yeah I'll go for that. Send me a pm if you want it.

When I looked into it before, it was possible to wire it all in without the need for an extra hvac harness as the standard fan control module (in a vr6 anyway) was setup to work with aircon, regardless of it being fitted or not, when the a/c is switched on, the fans should run at speed 1. The best way of looking at things, the air con system is a separate system to the cooling. The climate control will tell the cooling system that it is on and then the cooling controller takes its info from the brown plug in the thermostat housing and the pressure sensor (I think!) to keep the cooling under control. All the cooling system needs to know, is that the air con is on and within pressure specs!

I'll have to dig out my notes on exactly what pin does what but all 3 pins are all the same pressure switch which sits on one of the air con lines. As I said earlier, I've not looked too much at the air con side of the build as it's not the proity at the moment. I've still got plenty of other jobs to do on the car before it even moves from my driveway :-)

1.8t and 24v use the same ecu so the vast majority of wiring is the same. It's listed in quite a few places on the 24v conversion thread what is what. I made the loom myself with reference to the clubgti 1.8t thread and the vehicle wiring diagrams. Not too hard, only about 10 or 12 wires if memory serves me right. How come you decided to go 02m? Yeah it's 6 speed but the final drive ratios are broadly the same as a 5 speed rado box but with the penalties of much more weight, more shifting and additional mounting brackets.

You'll be surprised!

Nice one mate!

I used this setup: T17: 1: Blower Live from N1 2: Not Used 3: A/C "ON" Switch 4: RPM Signal from U1/6 5: Power feed from A1/7 6: Earth - I used the earth stud above where the ABS ECU lives, there are 2 earth points, either will be fine. 7: Not Used 8: Outside temp Pin 2 (Mk4 External temp sensor) 9: Not Used 10: Illumination feed, I took mine from the old heater control feed 11: A/C Pressure switch Pin 3 12: A/C "on" signal from ECU - I have a 24v so the pin out to for the ECU will be different for 12v 13: Not Used 14: Not Used 15: Not Used 16: Not Used 17: Not Used T12: 1: OBD Diagnostic feed 2: A/C Pressure switch Pin 2 3: Not Used 4: Not Used 5: Outside temp pin 1 6: Not Used 7: Not Used 8: Sunlight Sensor Pin 3 - The other sensor pin goes to earth 9: A/C Pressure switch Pin 1 10: Speed Sensor from W1 11: Not Used 12: Not Used I've not looked in how to wire in the 12v fan controller yet, i'll get back to you when I figure that out. May not be for a while as i'm not planning on getting the aircon fitted until next year .

I'm going to roll with Kev's idea of stock location myself! Looks great and gets the intake out of the hot air coming through the radiator on the right hand side of the engine.

Which plug combination version do you have? I've only worked out the pin outs for the 17/12 pin plugs.

Looking good Sean! It's quite some turnaround from the car you picked up!

That's been on this forum before!

C and R Enterprises are where I got my from. Cheap, Goodrich and quick delivery.

Yeah, my bad!

The 24v turbo stuff is pretty expensive compared to the 12v stuff, but not as expensive as the r32 taxed stuff!

Throttle pedal, bigger brakes if you don't already have them, the 24v powersteering pump with the 12v pulley and the cooling system a few posts up should be enough to get you on your feet.

Try the fuel pump relay, about 30 secs to replace and 15 quid from a dealer. Those are classic symptoms of a dead relay. Sorry back on topic.

No probs, anything, give me a shout!

I used the 24v pipe, it's a few mm longer than the 12v item. I matched that to the 12v thermostat housing as the 24v has a slightly different output for the pipework. Basically, plug the front of the engine where the 24v normally takes it's aux water feed from and then use a 24v crack pipe and use the original 12v cooling system. Relocate the aux pump to the stock 12v position and you're done! Virtually plugs straight in apart from having to shorten the length of the pipework going to the throttle body as the 12v and 24v throttles are on different sides.

Bump, need these gone!

Open to offers, need this stuff gone!
