Hi there! Great video, wondering about a few things. When you say something needs 12v power does that mean ignition power or constant 12 v power? Also the lilac yellow wire on the blue connector, do you connect that to ignition power to wake up the ecu if you’re not running the 109 relay? Thanks!
Hey adam, yep i mean constant 12v power. Pretty much the only thing that gets momentary power is the wire connected directly into the starter which fires the starter solenoid. You can run that one through a relay from your ignition. The lilac/yellow wire on the blue connector is hard to figure out honestly. It's something i was planning on running an update on once I get the system more sorted, but I think the lilac/yellow wire is the one that actually powers the relay... so once igition is swithed and the ECU gets power, the Lilac/yellow starts running high 12v supplied from the ECU. The one that i DID glance over in the video is that the dark purple wire on the T14 connector needs 12 supplied to it to wake up all the engine sensors in addition to the yellow/black wire. Hope that helps!
Also do those + and - have to be hooked up to run. I can get the engine to fire. The ecu is coming on and the injectors are getting fuel but all the engine will do is spin over
I found the answer to my question online 5 - 30a fused, 6 - 10a fused, and 9 - is a ground. The engine started right up. Now I have another problem with the TPS not working. Reading online that it could be the brake pin out.
Bennett, the ALH engine code came in the Volkswagen Golf, Jetta, and New Beetle, and a few other things from 1999.5 to 2003. Basically the MK4 body styles. This video applies to the engines which have the bosch VP37 injection pump.
I just used the Haynes manual which had a general wiring diagram, however I found it was just easier to trace back the components that I knew I needed to keep rather than tracking down individual wires
I'm not familiar with that engine, but from the name PD it's likely a pump duse VW engine which does not use the same bosch VP37 injection pump, but instead uses a different fuel injection pump. So no, I'm guessing this specific guide will not help you.
Hey Adam! I'm throwing this into my '97 TJ Wrangler but my goal was to show how the harness could be trimmed universally and be used in whatever. Hopefully should have my full swap done in a few months.
Thanks a lot for the whole series. It will help me a lot during my swap!
Thanks bro
Well done!
hi, i have a 1.9 tdi alh engine on my vw bora now, but im thinking to do a swap to 1.9 arl, i suppose that i need to change all the harness right?

@@FiedtheNeedIT1 I see! Yeah that’s great! So the dark purple wire on the T14 is switched power?
On the T14 connection will you give the numbers for the power and grounds. I don’t have that plug so I will have to splice into the engine harness.

do you not carry out an electrical installation like this ALH for a fee?
I'm interested in this can you make me a harness for my tracker swap I'll cover material and what not
Hi, thanks for the video, What year is the TDI engine?
Bennett, the ALH engine code came in the Volkswagen Golf, Jetta, and New Beetle, and a few other things from 1999.5 to 2003. Basically the MK4 body styles.
This video applies to the engines which have the bosch VP37 injection pump.
My 2003 beetle harness is little different, maf sensor has additional plug and is on the main body harness thats not pluged into ecu dirrectly.
What year is your tdi???
This is awesome! Any chance you have a wiring diagram ?
I just used the Haynes manual which had a general wiring diagram, however I found it was just easier to trace back the components that I knew I needed to keep rather than tracking down individual wires
what pin do you need to activate the starter?
and ecu to like power it like you turn on the ignition?
will this work on a pd130?
I'm not familiar with that engine, but from the name PD it's likely a pump duse VW engine which does not use the same bosch VP37 injection pump, but instead uses a different fuel injection pump.
So no, I'm guessing this specific guide will not help you.
What is this swap going into?
Hey Adam! I'm throwing this into my '97 TJ Wrangler but my goal was to show how the harness could be trimmed universally and be used in whatever. Hopefully should have my full swap done in a few months.
@@FiedtheNeedIT1 wow! That’s awesome I’m actually doing the exact same swap with a 97 Tj and ALH. Very good video thanks so much! 👏🙏🏻
@@adamsytsma5112 awesome, good luck with your build and let me know if I can help at all
Thanks I will!
You have time to make another? I'm on the fence of TDI or MTDI alh for this very reason in the wiring.
