AJQ Loom Conversion

Pirrol! Im spanish

my golf mk2 also mounts an ajq engine, we are doing the same swap jejeje, thank you very much for the info, the photos of flickr do not see me, could you upload it again? Where are you from?? I from Madrid

 

I'm glad it useful you my excel, all it was possible thanks to rubjonny, nowadays that excel has more modifications, How are you wiring your AJQ swap??? did you add a ECU relay or not??? if you want I send you a private message with my phone number and we works together about this thread, and we publised our conclusions for future swaps about AJQ engine code. Will be useful for other people.

 

Ive drawing a new NON ECU RELAY VERSION, I hope help you rober_20vt, I believe its correct.

ADDING ECU RELAY version has been posted previously for rubjonny.

hi guys!
What relay can I use as an ECU relay??? OEM relay is 428, but maybe 53 could works?
as you know I dont have relay 428. If both relays have the same diagram must be work... I believe.

 

Thanks rubjonny, Ill use 53 relay.
I have been searching more info about ecu relay and I have found that.
I need to check if my ECU has these pins previously, because this information is confuse, and if I need it, wiring these pins between ECU and ECU Relay.

T121/21 -> pin5/85 of J271(ECU RELAY)
T121/121 -> pin2/87 of J271(ECU RELAY)
1/30 loop to pin3/86 of J271(ECU RELAY). There J271(ECU RELAY) gets power (30). It is supplied via 10A fuse S10.
I need to join pin1/30 to 3/86? I dont understand why this loop.

following rubjonnys advise and this information I understool the following:

pin 30 ECU RELAY: Y spade(15A fuse)
pin 85 ECU RELAY: T121/21 and GND, but I though that T121/21 are +12... I dont understand this...
pin 87 ECU RELAY: T10i/8, T6m/1 and add T121/121
pin 86 ECU RELAY: G1/4(add 10A or 15A fuse), or G2/4 (OEM fused), and add loop to ECU RELAY pin30? I think this loop are innecesary.

thanks and regards

 

Just as it is in you previous diagram, perfect!!!
Thanks for your explanation, now I understand perfectly.

 

Hello
Im spanish too
This wiring diagram is correct for non ecu AJQ???
Its too easy to be true...
regards

 

Hi chapulin I think so.... Maybe rubjonny could confirm you, I did this diagram previously but I add an ecu relay after that, and I didnt test it.
I think that this non ecu relay diagram could work fine if you decide use it.

 

Hi guys!
When Ill add a new ecu relay (53), can I remove OEM relay number 32??? If i dont need it...
regards.

 

In that case, relay number 32 is for scrap.
Ill add my new ecu relay out of fuse box, in a new relay housing, as the mk4 oem ecu relay. Perfect
Thanks again dear rubjonny

 

Hi guys!
My mk2 AJQ its alive!
I wired how rubjonny said me and it was a success.
The only problem it was that throttle body non response, and I tried to move it with my hands and the engine plug off, after that didnt start again... could been broken throttle body?
Id other throttle body previously but it was broken because donor car had and accident, I changed for my current TB witch has the same reference, both TB are from narrowband ECU.
This weekend Ill wire VAGCOM port and try with TB alignment after deleting errors.
someone has any other idea about this?
thanks mates.

 

Yes TB buzzed approximately 10 seconds, and them engine start corretly. I need to wire diag port and check fault codes. :thumbs up:
I hope ecu is fine... Ill check lambda wiring too because I had read in some cases could has a wires damages.
