Thread: turbo timer for a 300tdi D1 fitup.

Are the yellow and blue wires thicker ?
If they are the ign. feed wires they should be the same as on the back of your ign. switch.
If the red is power it should be fused when you fit it.

Cheers.

hey mate,
not exactly familiar with this brand of timer. but from what i know of other timers, they you'll use wiring like:
Red - Constant +12V
Yellow - Ignition +12V
Black - Earth
Blue - Accessory +12V

Or cut the ignition wire on the back of the barrel, and connect Blue wire to one side, yellow to the other. So the timer is "bridging" the ignition line. Thinking of the circuitry, can't imagine it would matter which wire you connect to what side

as Alien said, you'll want to fuse the constant 12v (Red) wire.

g'day mate,

so fusesing it is just a safty things, i have installed only one before but the turbo timer actualy had a plug which is located under the dash of this truck i did, but did not have any fuse ???

yeh if it had a plug, it wouldn't need a fuse as it would be using the constant +12V that goes to barrel, which would already be fused from factory.

If you're running a new +12V line, usually a good idea to run a seperate fuse for it, just to isolate it a bit.

is this the 724/st4 model?
if so all the connections are done from behind the fuse box on the drivers side.
i have a 1998 tdi.
will pull down the fuse box tomorrow and give the colours and connections.

satellite fuse panel #1 is where most for the connections go to.

only fuses 1 and 3 get used on my timer hookup.
i definaltley have the 724/st4 model with 4 wires, red, black, white, blue.

my car manual list these fuses back to frnt so i will list them from left to right.

1. 15amp, one wire, bottom purple---- the red wire from the timer is linked into this one.

2. 20amp two wires, top brown, bottom blue-purple trace----not used.

3. 10amp one wire, bottom white-green trace---- this wire needs to be cut. the white wire from the timer gets connected to the fuse panel end of the cut. the blue wire from the timer gets connected to the now loose end of the white-green trace wire.

4. 5amp one wire bottom red-yellow trace---- not used.

5. 10amp two wires top white bottom green-pink trace---- not used.

6. 25amp two wires top purple bottom brown---- not used.

the black from the timer just gets earthed out to the car.


hope this helps.

thanks to all for the help. got it installed just fine with out any problems and is working well.

cheers simon

Interesting thread, I just picked up a 97 TDi and looking to do the turbo timer thing just incase the Mrs drives it (highly unlikely).
