I might be able to help you out with this, but I'll need you to let me know what pin positions your original tps wiring go into at the ecu. Very easy to do if you have a multimeter and do a continuity test to bell each individual wire.
Not so easy if you don't as you have to rely on checking the colour coordination.
When you know what wires go where on your ph1 loom, mention/quote me so I get a notification. That way I'll know when you've replied. :up:

Cheers. Ill get on the case the morn.

The 3 pins used on ph1 loom are 48,74,75

Ok buddy. Leave it with me and I'll have a scan through some pinouts.

@Doogimus the 6 wires that go into the ecu plug on your current loom need to be removed from your ecu plug. 3 of them need to then be transferred to the pins you stated above. It doesn't matter which 3, just remember the colours.
Cut the 6 pin plug off and fold back the 3 wires your not going to be using.
Now you need to look on the original tps plug and cut it off the ph1 loom leaving yourself a bit of length on the wire coming out the plug. Then it's just a case of connecting the 3 wires to the correct ones that go into the ecu plug, so if pin 48 at the ecu translated to pin 3 on the tps plug, it needs to do the same thing.
You'll find that the pins 48, 74 and 75 are already used on the ph2 loom. Pin 48 can be removed on the ph2 loom to make way for your new pin 48. Pin 74 should be unused, and pin 75 should be found at the 6 pin throttle body plug. Just double check, as you should be able to reuse it.
If any of that's not clear mate, just give me a shout and I'll try and explain it better for you. That's quite a mouthful what I've tried to write!

@http://www.cliosport.net/members/northloopcup.61663/ i checked the tps on the ph2 loom. The pins used on that are 62,61,17,7,13,82.
So pin 75 is not used for the tps.

Yeah apologies, I should've known that as I've helped another member with wiring a tps sensor in on a ph2 only the other day!
Just replicate the wiring for the ph1 on the ph2 loom mate, but make sure you remove the remaining pins mate. It's then just a case of connecting 48, 74 and 75 into the ecu plug and connecting the plug on to the other end.
It's when you go the other way and need to add the fbw throttle body wiring in that it becomes a bit of a pain.

@NorthloopCup ok thanks very much for your help.

No problem at all. Any stress, give me a nudge.

Glad I've found this as I'm fitting a cable throttle onto my cup and was wondering about the plug situation
@NorthloopCup
Hopefully I can work it all out from this.
Or do I need to fit ph1 ecu and engine loom?

Is it a ph1 ecu? Or a gen90?

It's a ph1 ecu @NorthloopCup

Happy days then mate. There's a few other wires that need swapping in the ph2 ecu plug, but can't remember which ones.

@NorthloopCup Sorry for all the questions, but I would like to get it sorted soon.
I currently have the ph1 inlet and cable throttle body fitted, ph2 engine loom and ph2 ecu.
I do have in the garage a complete ph1 engine loom and ecu.
I want to go to the cable throttle for reliability and response, and still need all the other bits n pieces to work.
Do I need to swop the engine loom from the ph2 loom to the ph1 engine loom and use the ph1 ecu?
Or use the ph2 engine loom, change the plug that goes to the TPS and swop a few pinouts to the ecu and use the PH1 ecu?
Help appreciated

To keep things simple you may be better off swapping out the ph2 loom and fitting the ph1 engine loom tbh. You need to check the wiring connections that go into the interior loom (n/s inner wing fuse box) are the same across the 2 looms though to be certain it's a compatible swap. Some of the wires going back into the car will be for the throttle pedal potentiometer, which you will no longer require for obvious reasons. You'll find these in the white multi plug connector.
That then should sort out the issue, but I can't be 100% as its not something I've done myself mate.

Fitting the Ph1 loom is the best option as Mark has said , I know the Ph2 loom doesn't have the idle valve wiring , and I think the Ph2 ECU wouldn't have the pins for the ICV also .
I have a pin out for a 182 but not a 172 cup but both are FLY BY wire Throttle.
I think you will need the Ph1 ECU also to run the ICV , unless you run a screw tyre adjustment on a manual adjustment.
Easily done , but wouldn't know if it would be enough to support idle after over run .
