Title: Clutch switch plug / what colour are the wires ?
Post by: tigers_gonads on 09 June 2016, 15:19:38
Gis a clue

I've got the 2 pin switch and have the fuse / relay boxes hanging out.
I've also removed the fuse box door for access but can I hell as find the mystery plug for this switch  :-[
Most of the under dash loom is unwrapped and I found the 4 wires which run to the brake pedal switch with ease but still no luck  :-[

Anybody know what colour the wires are on this invisible switch are ?
It might be easier to find the wires then trace to the plug  :-\

Also been blind without these glasses is a friggin pain in the arse because every time I stick my head under the dash, the oppsers fall off the end of my nose and can't see a bloody thing   >:( >:(

Oh yeh, i've stabbed myself with a Stanley knife while removing the loom tape so I think its fare to say, i'm having a bad day  >:(

Auto to Manual conversion Rob  :y

ECU needs a pulse from the clutch on gear change to let it know when to drop off the revs or it holds on to them for the torque convertors benefit  ;)
Mark has already done the Tech 2 bits but it is still showing gearbox faults due to the switch  :-\

It would also be nice to have the cruise working again  :)

No clutch switch plug in the auto loom. :P :D

Oh FFS  :(

Don't suppose you can get the plug separate so I can splice it into the cruise cut off circuit on the brake pedal ?




Would the lads who have 3.2 police specials or converted FL converted auto to manuals with a working cruise care to help out on this please

Some good news at last ...............

The missus has taken pity on me and is taking me down the local wetherspoons for my tea and a few beers  :y :y


No doubt i'll end up having a bad pint and end up sick as a dog later  ::) ;D ;D

Okay since I left the masters abode a couple of weeks ago after the tech 2 session, the EML light has been on.
I left it because I thought he clutch switch was causing it and this would clear when the offending switch was fitted.

Right, i've just plugged my slightly dodgy laptop based "My Naff Code Reader" friend in and this lot came up  :(

P0650  (4) Present
P1700  (8) ---"---
P1700  (0) ---"---
P0170  (9) Not present
P0150  (5) Intermittent
P0150  (F) -----"-----
P0150  (4) Not present

I cleared the lot and restarted the engine then re run the code check to find this  :(

P0650 (4) Intermittent
P1700 (0) -----"------
P1700 (8) -----"------

This lot have returned and even after clearing, return after start up  >:(

IS this lot down to the switch been missing ?
Could this lot cause the revs to hold on when changing gear ?

Other than the lack of cruise and the gear change been a ball ache when changing quickly, the can runs absolutely great  :y :y

When you next time down south pop down and will get sorted

Btw this fault it's not due clutch switch missing

On the Non DBW, one of the pins on the ECU gets a High or Low from the main loom, that tells the ECU whether its an Auto or Manual Gearbox fitted, cant image it would be much different on the DBW.

When I had a intermittent start problem on a 3.2 Auto, and having changed the Crank Sensor twice  ::), I borrowed the ECU from my 3.2 Manual Plod and vice versa, and the fault moved with the ECU confirming my thought about a faulty ECU, point being, neither cars complained about having an swooped ECU from a different GearBox and no codes was thrown up.

Cant remember if I checked the Cruise during all this, as the Plod doesn't have Cruise Stalk, but would have though it should have worked ok if the ECU was Cruise enabled.

If I get a chance this weekend I'll check if the 3.2 Plod Manual has a Clutch Switch fitted.

Money / work is tight again mate so I cant see myself down there in the near future but i'll keep in touch  :y
If I get the chance to go down to Skegness with the caravan, i'll nip out and pop in for a chat  :)

What are you thinks the problem might be ?

Cheers Chris  :)

Either way, to get the cruise working, I need a clutch switch sorting  :y
I might be totally wrong on this but i'm wondering it something on the Tech 2 session hasn't taken  :-\

I've just been down the M62 for the cars weekly blast and it drove great with the exception of the revs holding on when changing gear  >:(
Put it this way, I visited some back roads on the way back and on a couple of occasions, I gave it some welly in the first 3 gears (as you do  :D)
Between 1 and 2 and 2 and 3, the revs would hold on for upto 5 seconds with the clutch depressed and the foot totally off the gas pedal  :(
And even then, the revs would seem to drop off in stages instead of just dropping to idle when the clutch is disengaged and the foot was totally off the gas  :(

Certainly one confused gonads here  :(

Good point Al  :-\

Gis a clue, were is this magic box and i'll check in morning  :y

Tbh, that weekend was a bit of a blur  ::)
I did 4, 12 hour night shifts then drove back home from darn south that Saturday morning  :(
Toughed it out until 10pm then went to bed.
Spent Sunday trying to work out what day it was then back on the road to Sereks at 6am Monday morning !!
So to say I was knackered is the understatement of the friggin century and if i'm honest, I haven't got much of a clue what went on that day  :-[

Drivers side kick panel. Might also need to Unplug the blue? round plug by the battery assuming still got an auto loom fitted... ;)

Will do, cheers  :y

Just thinking .............. I know i've seen one box up around were the accelerator pot is with maybe bosch on it  just before my glasses fell off my nose and I stabbed myself with a Stanley knife  :-[
Am I right in thinking that this is the alarm / central locking box and NOT the gearbox ECU ?

Both in the same postcode ;)

If the central locking stops working, try the other one :D

Okay, transmission ECU unplugged  :y

Car starts and runs with no problem

Now the TC light is on as well as the EML light  :(

Plugged I the code reader to find the good old

P0650 still there but I don't really give a toss about  ;D but also i've now got a
U2106 - (4) CAN-Bus no Communication with Transmission Control Module present  ::)

Okay, I take it that the TC lamp and new code is because i've unplugged the ECU but why the TC lamp, I haven't got a clue  :-\
I think i've found the blue plug in the middle of the 3 at the rear bulkhead side of the battery  :-\
I'm just waiting for it to cool down a bit under there so is it definite that this plug needs to be disconnected or may it cause more weird going on's  :-\

Post by: 05omegav6 on 12 June 2016, 16:22:38
Until you tell the engine ecu that it's manual, you'll be stuck with the 2106.

Just at work, so don't have the reverse light wiring to hand, but am 99% certain that the blue plug is the gearbox loom and the reverse lights are wired through the white plug... Certainly when I fitted an auto loom to the manual car the reverse light switch was the only wiring needed ;)

Ideally you want to track down a manual 2.6/3.2 loom, fit it and get tech 2 to activate cruise and tell the engine ecu that it now has a manual box.

This probably didn't take before as it was still seeing the box ecu...

Okay, blue plug unplugged
Car will not turn over so I take it that the old gearbox start inhibitor goes through that plug  :-\

Anybody in OOF land got the schematics for this plug so I can see if they is a work around before I end up changing loom for a white plugged one ?

Ref this white plug / loom

Is manual loom on the PFL cars the same as the FL cars ?

No as dispack and throttle body looms are different...

Thinking this through... perhaps the ecu needs another talking to... if it can't see the gearbox ecu, then it should now accept that it's a manual car...

Without seeing it though, it's impossible to say how the wiring was tweaked to accomodate the reverse lights... assuming they work of course ;)

Perhaps Serek can elaborate for our benefits...

Okay, a update on this little saga  ;)

Popped round to the masters abode last night for a bit of investigation with his Tech2 contraption  :D

It would seem that even though the initial reprogramming of all manual settings was installed on the cars engine ecu a couple of weeks ago, because the gearbox ecu was left connected by myself the engine ecu could still see this and because said gearbox ecu didn't have a gearbox to play with anymore, it decided to spit its dummy out and throw codes at me  ::) Also when it was disconnected, it got futher upset and that's why I ended up with the TC light on too  ::)

Okay, a bit more info on the cruise setup .........

After we looked at the wiring diagrams on TIS, it would seem that the V6 manual facelift cars with cruise DO have a clutch switch and this is supplied with 12 volts from a ignition live fuse / circuit, through the clutch switch and back to a pin on plug X36 on the main ecu  ;)
Even though its all reprogramed and all warning lights have gone, the revs still hang on a little but nowhere as bad as before. Whether the clutch switch has a effect on the revs hanging on a little when playing I not sure but  we will see in the near future when i've sorted out the new wiring ect.

More details to follow later on pin identification ect and i'll take a few pickys to add to the guides when its all up and working.

If i've got any of that lot wrong, i'm sure somebody will be along soon to smack my legs  ;D ;D

As always, thanks to Mark and all others who have helped (including Serek who did the spanner work in the first place)  :)

Lol, ok...

Was sending you a pm instead...

Master has obviously worked some of his magic on it, so see how it goes I guess ;)

Meantime, see if you can't rustle up a 2.6 manual loom...
