    Hi

    I went ahead and bought a VR donor cos of its low mileage, originality and full VWSH but....

    it was an auto.[eek][eek]

    I've since changed the box to a V5 manual.

    I am about to start wiring up, keeping as much of the wiring as I can from the donor, inc. the fusebox, splicing the dash wires in.

    Am I gonna run into headaches adapting the auto wiring/ecu??

    Any help much appreciated of course!

    From memory it's all the same apart from the added gear selector. It will only start if it's in park and the ECU will always look for that so i think you have to do some extra wiring.

    Hi, bonus,

    The engine compartment harness of a mk.3 usually has a 2-pin connector breaking out the thick Red-black* wire for the starter solenoid (terminal/function '50' on diagrams). Automatics plug in the safety switching here, while manuals simply have a connector socket fitted with a wire loop

    * or is it Black-red? (and the breakout is on the cabin/fusebox side of the bulkhead)

    early corrado stalks are the same as CE2 mk2 golf so will plug in if you're going full ce2 conversion. you can use mk3 stalks as well with a bit of work to the hazard button if the roundy look tickles your fancy or you need a cheap emergency set of stalks

    they wont fit on CE1 ignition housing though so you'll have to swap that over plus the CE2 lock housing wont fit the MK1 column tube either so you need to chop off the mounting lug. Ideally re-weld it in the correct CE2 position but most just leave it off

    plus the ignition switch isnt the same either, but the mk1 ignition lock will fit a ce2 housign though if you want to keep your original key.

    Well I went for the Corrado stalks, I'm thinking of going quite minimal, no ignition barrel - push to start button so I'll have a little play around with that. Fully custom dash made by Sunseeker [8D]

    I wonder if the speed sensor from the auto box will work on the 02j [8-}]- haven't tried that yet!

    I wouldnt have thought so, but you never know. worst case splice the MK4 plug to mk3 wiring or hunt around for earlier 02A/J sensor with square plug not difficult to find

    you got 2 knock sensors and a crank sensor :)
    1 knock sensor is on the driver side near the MAF, the other one is on the gearbox side and the plug hangs about with the crank sensor

    Will the mk2 switch work with the original mk1 key/barrel? if I use a mk2 housing

    the ignition switch is different ce1 and ce2 as is the plug on the back so you'll have to splice that as well as the stalk looms etc. The pins are standard timer and widely available if you have a good crimp tool

    I actually have the donor mk3 key, however i didn't get take the barrel before I scrapped it. It has the immobiliser code doesnt it, so if I use a ce2 housing, with the immobiliser ring+ecu - I'd need a new barrel that works with the key - dunno if thats possible!

    Looks like its easier to just get a CE2 housing including the key, delete the immob and just have different door keys.

    you can swap the mk1 lock barrel into the ce2 housing then get a new mk3 chip key cut to your locks, swap chip and jobs a goodun :)

    before you do that though check to see if the mk3 key reader will fit under the mk1 ignition plastics. though on that note the ignition plastics probably wont fit the ce2 lock housing even if you cut a hole for the hazard switch? if so use ce2 mk2 ignition plastics the key reader fits under those no problem. maybe mk3 would work, though they're a bit wider than mk1/2 so may not look right
