Well, the harness arrived and I got started. I connected the one blue end to the ignition, likewise the other. Then I was left with a purple wire - connected to the handbrake, a weirdly shaped 3 pin connecter, and a single white wire.

After *******ising the 3 pin connector and wiring it into the control unit itself, and finding the earth etc, success!!! The tt was working when the ignition comes on, and engine running. Great!

However, It doesnt run on when the ignition is switched off. Now Im confused, but there is still a single white wire left untouched. After thinking bout it for hours, I must have to connect it to something, but all the guides and info I have found, are as much use as a chocolate fire guard.

Can someone please help me, so I can get it working properly,
Many thanks

 

easy mate, id the left wire the green one, if so dissconnect the blue and replace it with the white if it is thick enough, do the same, the blue is the aux ignition for radio/heaters like wise, if i am wrong post a pic and i'll help after football, if not already sorted it with this reply

 

Will give it a try!

 

What your missing is the perm live... it runs ok with the ignition on, but turn it off an it has no power for the timer to count down.

The black ( or black an red wire ) has to go to the Handbrake ( its so you can't drive off with the timer active an the ignition turned off ) or so i've been told.

the white wire, well thats not connected on mine either. an mine still works ok.

 

Id put the purple wire to the handbrake, and the black one off the control unit to an earth. Is this the wrong way orund then?

 

can u list the colours you have apart from the one's in the small plug they could be for rpm and tach

you should have

thick red - 12v
thick green - ignition main
blue - blue ignition accy
thin blk - ground
thin grey handbrake
thin white O2 sensor

can u post the model number of the tt please also

 

This is the one I have.

The wires are this:

On the control unit

Red - 12v Bty
Blue - Acc
Green - Ignition
Black - Ground
Purple - Handbrake

On the harness

Blue end and other blue end connected to vehicle original harness

Which leaves the 3 point connector and the white wire. The 3 point connector is connected as per a previous post, which just leaves the white. As was said before, it runs fine with the engine on, but wont count down as when I turn the ket off, the TT cuts off too.

 

i know i am a pain anychance of a pic if the wires in the white plug, or what colour are they, and where is this white wire

 

The wires in the white plug are the same as the picture above from SiV6Si, the white runs from/between the other connectors. Its basically the same thickness as the the rest of the harness, with a female bullet connector at the end. Cant get pic yet, but will try and find one on google.

tell ya what, start over connect as follows,

on your ignition barrel there are 4 wires, you need 3 of them,

red to main 12v supply of ignition loom,
green is the ignition input and tt run on connect this to the ignition that is live while crank, should be red/blue.
blue goes to the ignition accy, loses 12 under crank

forget about the white wire

 

Try the settings on the timer bud,i have the same timer and after my lad messed about with it it wouldnt work,press the left button till it say off,then twice and then u shud b able to set secs/mins with the right buttons,leave it there n try it mate....

 

Ill give that a go first, easier!

 

Right, ive now checked all the wires, and its still not right.

Purple - Live handbrake
Black - Ground
Red - 12v constant
Blue - Accessory
Green - 12 v ignition.

What the f***en 'ell am i doing wrong?

 

Any more?

 

Update, I sorted the wiring out, and now the turbo timer is working. However, I need to connect it to the alaram somehow so when i take the keys out, and the tt is running on, i can remote lock and set the alarm. Anyone help?
