OEM management wiring: 1.8T => Mk2 harness install FAQ

this mite sound silly guys but where would the two pin plug from the alternator go to ? and who can i buy the tach adapter from for the revo thanks for help i am starting mine soon i just need to sit the engine in also who has any info on wire tucking how does the extra lenth of wire affect it resistance wise?

 

hello can you tell me where the two pin plug fom altinator will go to thanks

 

Johnny what's this second wire that goes to the ECU? I vaguely remember when I did my loom many moons ago now getting shot of a wire I labelled alternator lol because I assumed at the time I could just run the mk2 blue exciter wire from pin 2 on my alternator to the fusebox. Might have to have a sift back through the wiring diagrams & see how it links up, think it was located in either the orange or white connector on the 20v...

 

I want to ask.. Do I need to have switch on clutch pedal when AGU is swapped to mk2 ? I didn't delete wires from the loom and left that. The switch itself is not adapted to mk2 pedal yet, but I have it. Just wanted to know if it's influence operation of ECU.

 

Hello everyone! Wanted to thank Mr. 20v_Jimmy for taking the time to organize this data. Thanks to this write-up and my Bentley manual, I am now a proud 20vt driver too! Still a ton to work out, but this thread was a great resource for getting the thing running.

Here is my "pavement-princess" with her new power plant:



I found it easier to print, cut and paste wiring diagram pages to get the "big picture".

 

i know there is many ways of making a rev counter work, but would the link below also work?

My friend is undergoing this conversion in his CE1 carby mk2, does he need to keep the mk2 coil wires or can he cut them out?

 

Awsome thread guys! Thanks!
Ive been following the wiring hints in this thread and a few others ive researched. I got the AWW 1.8t to crank and start in my mk3 using this table that I made.



I still have to hook up some of the A/C connections from mk3 to mk4. I have a few strange problems though.

- When I turn the key to the ON position the clock and ODO go blank. Also, the temp and fuel gauges dont move. I think the cluster power gets cut when the key is in the ON position. A few warning lights come on though. After I turn the car off the clock resets.

- No MIL light, I'm not sure which wire from the mk4 side goes to g1/9

- No tach


Anyone with any suggestions?

 

Hi i may have missed this but could you help me im trying to wire a agu engine into golf mk3 some1 said they could do this but when i checked they put t6 pin 1 into g1pin4 so they say but thats a double black wire is this correct?or they got pins wrong?please please help me thanks

 

Here is a swap table i made.

everything works so far except I'm having trouble with the VSS signal to the ecu and the MIL.

My speedo works but there is no signal to the ecu. I pretty much have the VSS wired directly to the ecu right now. Do I need to wire it to the mk3 cluster's speedo output? Or do I need to install a mk4 cluster?

 

Im having some issues wiring in the fuel side of things, I dont get what g1 is that you refer to ?

Anyone any ideas ?
