scottybo Posted January 21, 2014 Share Posted January 21, 2014 so for my new engine (1.8 130) I have an 'aqua' ecu. key chip, and transponder ring. is there anything else at all that i will need to make this ecu work and run with the engine that i have got. i believe it all came out of a mk5b cabriolet and will be going on my mk6 any advice will be greatly appreciated as this electronics and ecu lark is way above my head im afraid Link to comment Share on other sites More sharing options...
JC Posted January 21, 2014 Share Posted January 21, 2014 correct me if i'm wrong you are adding a mk5 ecu to a mk6? so there may be some wire changes? Link to comment Share on other sites More sharing options...
scottybo Posted January 21, 2014 Author Share Posted January 21, 2014 Well there was no mk6 130hp. As i said i believe i came from a 5b. anyone able to help? Link to comment Share on other sites More sharing options...

Andy 3i Posted January 22, 2014 Share Posted January 22, 2014 What ecu was fitted to the car previously? You'd need to see if the pin outs were the same Link to comment Share on other sites More sharing options...

JC Posted January 27, 2014 Share Posted January 27, 2014 have you got the pin out diagrams for both ECUs? Link to comment Share on other sites More sharing options...
scottybo Posted February 1, 2014 Author Share Posted February 1, 2014 have you got the pin out diagrams for both ECUs? no i dont im afraid. can u point me in the right direction of where i might find that? Link to comment Share on other sites More sharing options...
opexo Posted February 18, 2014 Share Posted February 18, 2014 (edited) Okay, for this engine there are 2 ECUsone is with external EDISandone is with internal. Your ECU, AQUA has internal EDIS, which is better imo! So if your original harness is for internal EDIS - plug it in and happy tire squeeling.If not - i'll have to dig through old messages in our forum where i wrote to a buddy in your situation but with external EDIS how to rewire it. It's about 4-6 wires easy iirc. Edited February 18, 2014 by opexo Link to comment Share on other sites More sharing options...
opexo Posted February 18, 2014 Share Posted February 18, 2014 I did a bit of searching for ONIS ecu. I found out it's SKU is 98AB 12A650 AWB and im pretty suspicious it has PATS which might complicate things a bit. Need to get the wiring diagrams from AutoData and/or Tolerance (but they are a bit messy in some years) to figure out which wires to go where. OR i can post what is necessary for AQUA ecu, rewire the plug, cut and isolate the ones which won't be needed and finally rewire the rest to the missing sensors.OR better just get a wiring harness from the scrap yard:) Link to comment Share on other sites More sharing options...
scottybo Posted February 19, 2014 Author Share Posted February 19, 2014 any help u can provide would be really appreciated Link to comment Share on other sites More sharing options...
opexo Posted February 24, 2014 Share Posted February 24, 2014 this is for the Mondeo 2.0 ECU, no PATS, internal EDIS and yours (AQUA) should be the same. Maybe except:- fan control pins (for example pin 13,15,31) because yours is controlled by a thermal switch on the hose between thermostate housing and radiator i guess. You can rewire your fan relay to be switched from pin13 tho and get rid of some wires around the engine and the switch on the hose.- egr stuff (pin 27, 33)- pulse air system...

(the middle, 2, is constant "+" on gnition key ON/Running) crankshaft sensor:rewire: pin5 of EDIS plug to pin56 of ECU plugrewire: pin6 of EDIS plug to pin57 of ECU plug tachometer:rewire: pin11 of EDIS plug to pin4 of ECU plug And maybe a wire from the fuel pumps "+" to pin8 of the ECU plug. IF the ECU harness of your car is for ECU with PATS - DON'T do it. I dont know which wires to remove and what to do with them atm.Basically with the above and with enough free time to spend on the car you can rewire anything, just have to be good with the multimeter. Separate all wires to the engine - sensors, coil, injectors ect. and rewire them to the according pins of the ECU plug. Link to comment Share on other sites More sharing options...
scottybo Posted June 4, 2014 Author Share Posted June 4, 2014 both the ecus i have are pats im afraid Link to comment Share on other sites More sharing options...
scottybo Posted June 5, 2014 Author Share Posted June 5, 2014 so if i had the pin out diagram like you have provided above for the dek ecu, but for my aqua ecu, i recon i could rewire it Link to comment Share on other sites More sharing options...
