hi peeps trying to build a mk2 ayp loom going to need help with a couple of pins outs and connections at the mo, if not shortly to start with does anyone know the pin outs for t14b so far i have got t14b/2 t14b/3 both go to fan control unit so not needed in a mk2 can anyone help with the others plz thanx in advance, barry ps i would check against the other half of loom but that in my bro's garage 60 miles away
i have the seat ibiza diagram in my sig, you'll also need the round plug pinout in there if you're really strugglign I'll decode it for you tomorrow as I'm leavign work now
if you could that would be great, ive looked at both 6k1aqxaypecu and also 6k1 basic equipment diagrams in your sig and can only find reference to t14b pin 2 and pin 3 cant find any other pin outs unfortunatly. ps, its an ibiza loom
T14b is the radiator fan control unit, you can bin off all the wires to this and just use the factory mk2 fan wiring instead. you would only really want the fan controller if runnign aircon or if it was a 5/6 cylinder to control the electric coolant pump T28 1 - crank sensor pin 3 - ecu pin 82 2 - crank sensor pin 1 - ecu pin 108 3 - fuel injector #4 pin 2 - ecu pin 88 4 - fuel injector #2 pin 2 - ecu pin 89 5 - crank sensor pin 2 - ecu pin 90 6 - oil pressure switch - G2/10 or G2/11 7 - coilpack #4 pin 3 - ecu pin 94 8 - coilpack earths - battery -ve 9 - coilpack #2 pin 3 - ecu pin 95 10 - fuel injector #1 pin 2 - ecu pin 96 11 - fuel injector #3 pin 2 - ecu pin 97 12 - knock sensor 2 pin 3 - ecu pin 108 13 - knock sensor 1 pin 2 - ecu pin 99 14 - coilpack #1 pin 3 - ecu pin 102 15 - coilpack #3 pin 3 - ecu pin 103 16 - knock sensor 1 pin 3 - ecu pin 108 17 - coil live feed - G1/10 18 - knock sensor 2 pin 1 - ecu pin 106 19 - knock sensor 1 pin 1 - ecu pin 107 20 - ecu sensor earth - ecu pin 108 21 - throttle body pin 6 - ecu pin 91 22 - throttle body pin 5 - ecu pin 118 23 - throttle body pin 4 - ecu pin 84 24 - throttle body pin 3 - ecu pin 117 25 - throttle body pin 2 - ecu pin 83 26 - fuel injectors pin 1 - Z/1 27 - throttle body pin 1 - ecu pin 92 28 - N249 pin 2 - ecu pin 9 T14a 1 - fuel pump power for engine loom - G1/8 or Z/1 2 - N112 valve pin 2 - ecu pin 105 3 - N75 pin 2 - ecu pin 104 4 - cam sensor pin 2 - ecu pin 86 5 - ecu temp sender - ecu pin 93 6 - dash temp sender - G1/3 7 - PAS switch pin 1 - ecu pin 49 8 - PAS switch pin 2 - ecu pin 50 9 - earth for dash temp sender - head or battery -ve 10 - speedo sensor pin 1 - G2/4 if using 11 - speedo sensor pin 2 - G1/11 if using 12 - speedo sensor pin 3 - earth if using 13 - inlet temp sensor pin 1 - ecu pin 85 14 - cam sensor pin 1 - ecu pin 98
cheers jonny your are a star as normal, you have also confirmed my wiring is correct thanx again barry
have just had a loom done for 1991 mk2 16v golf gti to fit ayp dbw setup it starts idles . Throttle body has full movement with pedal but bares absolutely no affect on rpms I’m stuck also has no signal from ecu for fuel trigger. with what to do has something been missed ? It’s had o2 post cat sensor removed Sai removed ‘brake ‘clutch abs ‘and wiring for these parts removed too etc removed any help would be very much appreciated. My first ever time on here hope I’m relatively clear it’s ce2 Sorry if I’ve posted wrong place etc too
did you do the loom yourself or was it done by someone else? the loom builder woudl be the best person to ask as they'll know what exactly was done. heres a full ibiza -> ce2 guide: https://www.clubgti.com/forums/inde...-general-fusebox-plug-reference-guide.285928/ I would start by checking fault codes and scan through ecu measuring blocks make sure all is well there. if its not been wired in then its the grey/white on ecu pin 43 which needs to run to diagnostics port pin 7, then give the port live on pin 16 and earth pin 4. for fuel relay trigger this is a green/white wire from ecu pin 65, if you want to use the factory fuel relay on the fusebox it goes to g1/3
