OEM MK4 management wiring => Mk1/2/3 harness install FAQ (Now with added dieselness!)

Legend mate, thanks a million

@rubjonny hey bro have a question
I’m trying to use a tach adapt for a 3.6 swap but I can figure out where I can get the RPM signal?

 

Engine came from a 2007 Passat and I have already a tach adapter but I’m not sure where I get the rpm signal from coils or from cams sensor ??

 

R36’s ECU No pin 37 showed in the Ecu (no cable)
On a r32 ECU pin 37 wht/gry go to some
winter driven program bottom (if equipped)
engine code bud

Hi mate

One more technical question if thats ok?

Regarding clutch switch, whats the conditions? Should it be open or closed circuit when Not pressed down?
I know it should get +ve feed to ecu. But when pressed or when depressed.

am using old mk1 brake switches installed on the clutch hydro pipe to slave cylinder as in picture.

thanks mate

 

ok excellent, i use the other terminal on the switch to give it 12v when not pressed.

thank you again mate.

 

thanks mate

 

Hello

I've bought a mk3 golf with a 1.8t AQX. It runs, all the lights work, the dash shows when the lights are on. Can I make the speedo and the rev counter work?

It has a t14 plug, so I should connect pin 2 to G1/4 and pin 10 to G1/11 if I'm right? Will this make the speedo work?
What about the rev counter? It's not mentioned fot the t14.

Thank you for helping

 

I am using the original SEAT harness, there is a big round plug. Do I need to do something with it?

 

So apart from an accelerator pedal issue some months back my AUQ in a Corrado has run well from this guide. Unfortunately the following arose recently, normally from a hot start it will idle very lumpy and struggle to accelerate cleanly and then after a few mins the accelerator will do nothing. If I clear the codes it's as good as new until the next hot start. Codes as follows

17972 Throttle actuator J338 under voltage during basic setting p1564 intermittent

17705 pressure drop between Turbo and Throttle valve p1297

17579 Angle sensor 2 Throttle motor g188 not a plausible Signal p1171

17608 Boost pressure control valve mech malfunction N249

18010 power supply terminal 30 voltage too low p1602 intermittent

17987 Throttle actuator J338 adaptation not started p1579

So it seems Throttle actuator an issue but possibly power or wiring related then there's diverter or N249 valve involved. Anyone got any advice on how to best go at this? Thanks

 

Hey Jhonny question on swaps 3.2,3.6 it’s ok use
428 relay for main power ecu and coils? And for the rest of the accessories,Which relay do you recommend to have enough and constantly power??
I know For fuel pump main relays is 167 but for the others components
And I’m talking about doing a universal wiring his own relay and fuse box not on a ce1-2
