Title: mk4 golf engine harness with a b5 a4 ecu???
Post by: EuroXs4 on January 31, 2017, 11:15:44 AM
Hey guys I am wondering if its possible to use a mk4 golf engine wiring harness with a b5 a4 ecu???Just wondering if its a plug an play solution or if the ecu needs to be reflashes to a different software??Or if using a b5 a4 ecu is even possible???Im only using the engine harness and ecu nothing else.

I only ask because Im swapping a engine from a4 into a mk2 golf.Was hoping to be plug and play if I use all the sensors from the a4.

Have done a few PD conversions into Mk2 golfs and always use mk4 Golf looms, As long as ECU is PD no real problems,
although always better to use the ECU that came with the engine  :)

Thats the plan.Wiring,sensors and ecu from the same car.Now I gotta figure out how to waterproof the ecu.LOL

Not too much rain in Portugal LOL !
If you look where they put the ECU´s on MK3 & 4 golfs you´ll see its only under a plastic cover by the wiper motor
and they seem to survive ok. I´ve seen them wrapped in plastic bags before now  :D
