1.2 16V to 172 conversion questions

[Fred@BTM]

righto then

wiring, not my favourite subject!

i have 3 seperate looms that came with the engine, 1 is the engine loom (ecu, injectors etc) i understand this one!

next is the UCH under dash loom, now do i have to install the complete loom, or can i just swap the UCH etc etc onto the 1.2 16v loom already in the car?

the 3rd loom looks like its for lights etc etc, ie not relevant

16v jon??? Batman?? help!

What version is the 172 loom?
Cup FF?

 

[edde]

Fred from the looks of the wiring diagrams you could use your old looms but for the effort I wouldn't bother just swop the whole looms. OK your dash needs to come fully out and its more work but you'll need to work out your ABS and PAS systems anyway.

 

[Fred@BTM]

its 172 proper cup

ABS and PAS is ok, 16vjon sent me the diagrams on how to do that

 

[Fred@BTM]

if some kind soul coul e-mail me the wiring diagrams or the 1.2 16v and the 172 cup that would be lovely!

 

[Fred@BTM]

not messing about there. just been looking at adamhodg's couple of pics i took on my mobile. fair to say i wont be attempting one anytime soon

Wow Fred, you don't mess around - looks like you're making some rapid progress there! Hope the wiring goes ok - never enjoyed that side of things myself either!
Are you keeping it looking as it was outside? (with the green rims?) or is there going to be a new look to go with the new engine?

Edit: Just noticed the bonnet stay! I have something similar in the garage for my mini...

 

[Fred@BTM]

new look for 2007 on the way

uch will need to come from the original car..matched with immobilisor mate.
key/immob/ecu/ all matched.

 

[Fred@BTM]

yes i know that, but do i have to use the loom attached to the 172cup uch etc? or can i just swap the uch and bits onto the 1.2 loom in the car? ie save me taking the dash off to change the looms

 

[clarkiev6]

looms should be the same mate..

 

[Fred@BTM]

sweet!

 

[cK]

rubbish

 

[RSTuning]

Fred i can help you with the IMMO side if you need.

[clarkiev6]

the block connectors to the uch are standard now... like on the megans..the uch will interchange ..its the unit itself that varies due to the spec of the car.

 

[Fred@BTM]

so basically

pull out my old uch, decoder ring, clocks and ignition barrel

then whack in the 172 cup parts, hook up the fag lighter and off it go?

Give it a go its the easy option. I'm trying to read the drawing but there impossible.

Don't forget the PAS pump needs removing.

 

[Fred@BTM]

PAS pump is in the bin

i have to wire up the electric PAS and ABS

i'm using the 1.2 hubs and driveshafts! should be interesting!

I assume your using the ABS system to power the speedo if so least when/if you need to chnage boxes you cna use any box not just a Cup box with its speedo sensor.

1.2 shafts humm can we guess now long they last? I'm guessing two months.

 

[Fred@BTM]

there's not much difference between the 2 shafts

speedo i'm not sure what to do with it

Just though I gues your using the Cup dash?

If so then you'd need a Renault Clip to swop the dash over to think its got an ABS system IMo its worth it. Only issue is the ECU has a speedo in line so it tuns the fans on /off at different speeds depending on temperature but IMO thats no issue.

lol, can see where your driveshafts have modified the bodywork in that one.

 

[Fred@BTM]

oh yes!
