well all going to plan just but got a mental block a few questions
1 none return valve on servo where to get one and where to fit it ?
2 do I use black white wire to power immob
3 50 amp glow plug fuse strip I broke do I need to replace ?
4 got a few wires spare in the loom in the engine bay blue / white trace wire ? brown / black trace ? green / black trace ? brown / white trace bit thicker than the rest ? white / blue trace where do these wires go
got the conversion bible think I been looking at wires for to long I got head mush
will it be ok to directly fix ecu to bodywork without bracket ? cheers in advance

1 - scrappy?
2 - any switched 12v supply will suffice
3 - nope
4 - off the top of my head , no idea.
Fixing the ECU directly to the body is okay.

great just the wires now hope to get running by 29 june 48 years young then

Unfortunately I don't have my notes to hand.

Some of those wires are not used so you can ignore them.
They are detailed in one of the sheets that come with the bible.

Okay the blue/white is most probably the glow plug sensor - not needed.
Brown/white going to the dash could be the cylinder head earth.

The others you'll have to trace, if they're going forward into the bus loom they are most likely for the dash.

The coil has a Brown/black

If the blue/white is coming from the ECU then it's for the speed sensor - not needed.
Green/black from ECU is for the rev counter- not needed.

Are the wires coming from the ECU loom or the bus loom?

sorry yes all coming from agg loom except blue and white that comes from 3 pin plug not sure but mite be golf gearbox plug

blue / white

VSS input to ECU

89wedge wrote:brown / black

ECU to F87 Fan run-on switch to J293 rad. Fan cont. unit

89wedge wrote:green / black

ECU engine speed to dash

Engine earth (not return path for sensors on T3)

89wedge wrote:white / blue

G22 Golf gearbox sender via engine harness (not reqd. on T3)

great where will red white vag port go to ?

The 'OBD' port normally gets its power from battery + via a fuse.

super-duper

right immob wired up but have I extra gray wire coming out of immob next to grey white wire with little brown connector on the end ? where will he live

The immo box feeds the obd connector.

Immo box pin 1 to + 12 (switched if you wish)
Immo box pin 2 connects to ECU T68 pin 43
Immo box pin 3 connects to obd pin 7.
Immo pins 4 & 6 connect to earth.

OBD pin 16 to the same +12 as above
OBD pin 4 to earth
OBD pin 7 to immo box pin 3

The small brown connector used to connect to TV14 which is the self diagnosis wiring junction.
You don't have it nor do you need it.

thank you that's great hope to be running in a few days well hopefully

omg it runs bit lumpy on throttle but what a sound of sweet music can now concentrate on all the little fiddly jobs like to thank everyone for advise and of course garyd for wiring information will update when closer to full completion
