HI I NEED SOME WIRING GUIDEDENCE

can any one help me in try to wire up my engine

i have a audi a4 engine 1.9tdi afn not sure of age
it came with a loom <a bit choped up the lad said he ran out of spare time to finish it>
ecu ,clocks , throttle pedal

im hoping some one can tell me witch wires i need to start engine or possibly send me a easy to follow guide

Hey, I think you messaged me on youtube.

I was thinking, if you really struggle with it then you could send me the loom and I can try and make sense of it for you. I could try it on my engine but only if it has the same connectors, i.e. the round one for the sensors etc and the 12 pin one for the pump.

What are you doing for clocks? New electronic ones or sticking with old mechanical ones? If you're going with electronic then it adds a fair bit of complexity.

Cheers, Dave.

Haha, or send it to me as I can do those in my sleep.. almost !

And the late electric clocks are pretty simple too. Link

hi guys
yes dave i was following your youtube videos hoping for an in depth engine wire up

my problem is iv not seen engine running and im not keep on spending 300 pounds on loom just to find out engine shot of worn out

has nobody got a quick sketch of which wire i need to power up
and if im not useing audi clocks then emmo is in clock so is there a quickcupple of wires i can cannect to make sure engine is good the i dont mind spending money
if that makers sense

Hey Boonflap,

Well, it's not really as easy as just attaching a couple of wires, you have to make sure all the grounds are grounded and all the +ve's go to the right places (i.e. Ignition or Battery direct).

Also you have your Immobiliser to contend with. This isn't in the Clocks, its actually in the Engine ECU itself, you need to turn it off by opening up the ECU and changing some Data in one of the little chips on the board. I can do this for you if you need. You can also get an immobiliser 'defeat' board from ebay which simulates the original VW immobiliser and allows you to start the engine, that's about £10.

If you try and use it without dealing with the immo then it either wont run at all or will fail after a few seconds. Which ECU do you have? 1 long square plug (MSA15) or 2x plugs (EDC15)?

I have the circuit diagrams laying about somewhere but they are just the original Audi Drawings which I used to trace the wires from the ECU and clocks. It sounds Daunting but it's not that bad, Your engine will run fine without the clocks but only once the Immo is dealt with.

Send me your Email address in a PM and I'll send you the PDF with the wiring diagram, it won't allow me to upload it here as it's too big.
