Evening, after being away from the Volkswagen community for a while I decided it was time to do something with my old mk2 gti. A friend of mine had told me he was breaking a mk3 golf gti 8v, so I said I'd take the engine and wiring loom off him to put into my mk2. I spent the weekend removing the old broken 1.8 engine. And putting in the mk3 lump. The car is a H reg mk2 so I believe the engine code for that is PF? The new engine I have installed is from an R reg so I believe the engine code to be AGG? I have installed the engine but not the wiring loom, and as expected I have noticed that there are some differences between the two looms. I have been searching high and low and found a lot of information that has helped me get to this point. Am I going to need to install the mk3 loom or can I get away with using the mk2 wiring? Is there anything else that I will need? Any help is much appreciated. Thanks, Nathan.
