Im sure this has been asked a thousands times,but im doin an audi a3 agu in my golf mk2. My wires to the orange+brown connector are diff colours to the info i found ive got on mine,ill list the pins Brown plug 1 purple/black= ecu live ? 2 red/green - ? 3 red/ black caseing-starter ? 4 red/purple-? 5 blue yellow - ? 6 empty and orange plug 1 grey/white-diagnostics ? 2 green/white- ? 3 purple/white-? 4 empty 5 empty 6 blue/white-? 7 green-? 8 blue/red-? 9 green/brown-? 10 brown/black Any help would be great

if its early one, the pins a bit different: T6 - brown 6 pin connector, in connector protective housing, on left in plenum chamber 1 - blk/pur - AGU ECU pin 1 (coil live feed (15) in dash panel) 2 - red/grn - Reverse light switch pin 1 (manual models only, coil live feed 1 (15)) 3 - red/blk - Starter motor pin 50 (ignition switch pin 50b, or starter inhibitor pin 8 on automatic models) 4 - red/pur - AGU ECU pin 3 (Positive connection (30) in engine compartment) 5 - blu/yel - lambda probe pin 1, maf pin 3, carbon canister pin 1 (Fuel pump relay output (87a), in engine wiring) 6 - yel/blk - Unused or crankcase breather heater, comes from Fuse 34 (Fuel pump relay output (87), in dash panel wiring) T10 - orange 10 pin connector, in connector protective housing, on left in plenum chamber 1 - gry/wht - AGU ECU pin 19 (Dash plug pin 5, diagnostics k line) 2 - grn/wht - AGU ECU pin 18 (mpg signal) 3 - pur/wht - AGU ECU pin 4 (fusebox pin S3/6, fuel pump relay pin 85, (earth trigger)) 6 - blu/wht - AGU ECU pin 20 (Connection (speed signal), in dash panel wiring) 7 - grn - AGU ECU pin 8 (aircon) 8 - blu/red - AGU ECU pin 10 (aircon) 9 - grn/wht - AGU ECU pin 6 (rev counter signal) 10- brn/blk - Reverse light switch pin 2 (manual models only, output to reverse lights) T10w - white or T10d - green 10 pin connector, in connector protective housing, on left in plenum chamber 1 - wht/red - AGU ECU pin 43 (diagnostics port pin 13, unused) 2 - org/blk - AGU ECU pin 41 (can-bus high) 3 - org/brn - AGU ECU pin 29 (can bus low) 4 - wht/red - AGU ECU pin 9 (clutch pedal switch, manual models only) 5 - brn/red - Alternator pin W (unused on petrol models, assume rev counter signal for diesel?) T10a - 10-pin connector, left side in cable housing on chassis leg 1 - blk - Oil pressure switch (Dash plug pin 10, oil pressure warning) 2 - blk/wht - Speedo sensor pin 1 (Coil live feed 1 (15), in interior wiring, fuse 7) 4 - pur - Dash coolant temp sensor pin 1 (Dash plug pin 8, coolant temp) 5 - red/pur - Fuel injectors 1-4 pin 1 (Fuel pump relay output (87), in dash panel wiring harness) 6 - yel/blk - Inlet cam control valve pin 1, Turbo air recirc valve pin 1 and Charge pressure control solonoid pin 1 (Fuel pump relay output (87), in dash panel wiring, fuse 34) 7 - brn - coilpacks output stage pin 3 (Earth connection 1, in engine compartment wiring) 8 - blk/pur - coilpacks pin 15 9 - brn/wht - Dash coolant temp sensor pin 2 (Earth connection (sender earth) 1, in dash panel wiring) 10- wht/blu - Speedo sensor pin 2 (Dash plug pin 28, speedo)
Jon.. I have know watched a lot of your amazing tutorials and learned alot. Sorry for my bad spelling. But I cannot understand what to do. I have an AGU loom and whant to make it fit my CE1 golf mk2 fusebox. Can you give me some help? When I looked at the OEM harness forum that you wrote I started to figure things out. But when I googled some more I found this thread and you explained the pin connectors, ecu. But I can´t figure out which thread (OEM Harness or this thread?) I should follow. For instance, T6, pin 5 goes in CE1, E/14? Correct? Grettings from Sweden
this is the most complete thread so I recommend you start there: https://clubgti.com/forums/index.ph...install-faq-now-with-added-dieselness.267196/ depending on the 20v you start with afects where you pull all your power feeds from. an AGU would be ok from E/14 spade so long as the wire from it is a decent size, the earlier kjet ones are pretty tiny and so I wouldnt want to put any real load on it. later ones are much thicker so fine, and the AGU will only have the maf and lambda fed from it so no problem. But an R32 for example would have a lot more feeds powered from here so I would consider using an inline fuse on spade N instead, same goes for your AGU conversion if the E/14 wire looks a little too thin for the coilpack and ecu power T6 black and T14a/8 purple/black I would power both from an external relay clipped above the fusebox. put a 15a fuse on the permanent live feed to the relay and tap your ecu permanent live to the same fuse, 2 birds with one stone and it'll be kinda like how VW wired in the later DBW ecu from the factory
Thanks for the reply Jonny! So if I get it right. I can follow your flow all the way from the thread you have given me? And my power feeds should be thicker and use a fuse ontop of fusebox? Thank you again.
yeah make a judgement call. the e/14 spade on early GTI is too thin really, but later ones its fine. or if worried, just run an inline fuse from the large spade 'N' at the back of the fusebox, this is still fuel relay power but can take lots of load as its originally used for glowplugs
