simplest way of converting a 1990 mk2 PB to VR6

vr6 arb is completly different fitment, its no good to you.

191 199 171 E is oem MK2 radiator carrier, the part you need is:
3A0 199 201 B - 177+VAT
89-95 Corrado VR6
88-97 Passat

3A0 199 201 D is the toledo, fitted to 92-99 models with ABF

 

if its deffo toledo abf one yeah its what you need, just make sure its engine support part not rad part. or both if still together is fine

 

pull the transponder ring from around the barrel, then follow the wiring to the box. this box has wireing to the immob jumper block above the fusebox, it also has earth & ign live feeds.

As above if you want to use the orig vr key(s) to run your car pull the ign housing out. otherwise you can get a blank MK3 transponder key cut by a locksmith to match your locks, then just pop the chip out of the VR6 key and fit it to your freshly cut one. For the short term tape the VR key into transponder ring and stuff it behind the dash, or do it like that permanent like if you dont care about having the immob working.

Dont forget to pull out the diagnostics connector, its next to the ashtray behind a panel that slides across. Also note there is a single wire from engine loom to transponder box, you can see the wire i mean in the bottom pic, its the grey/white wires with brown plugs:

 

no, but i beleive the tumblers from the mk3 locks will fit the mk2. as i say tho, buy yourself a mk3 transponder key blank off ebay, pay locksmith 1 odd to cut it to match your old key, swap chips over

 

depends on where the alarm is spliced into! usually most of the splicing will be to ign switch and fuel pump. obviously if antyhting is spliced to the engine loom, then this will be removed. if you carefully document each pin that is spliced into, you should be able to add it back into the VR loom the same way without any fuss.

 

depends what the wires you leave disconnected do

the MK2 1 touch fob thing remove it and throw in the bin, no need for it since VR already has an immob built in. As for the alarm, do you actually want it?

 

the green plug also does the brake light switch, i left it intact as you can just swap the mk3 green plug into the mk2 fusebox. doesnt actually matter what you do, all that matters is the black wire to this plug gets ignition (coil) live!

jumper block is literally just there to connect the grey wire from the transponder box to the grey/white wire on the diagnostics plug. you could just solder em together if you wanted and bin the jumper block. I'm an OEM freak though so I want it exactly as VW intended.

 

dont need to add brown & red, those arte for the brake light switch. just need to add the black wire to the mk2 plug, or just find another ign live feed

just have to make sure its a coil live i.e. live with ign on and cranking, not x-over live which is only live with ign on and not cranking.

whjat i would do is pop the black wire out of the mk3 plug and pop it into the mk2 plug in the same spot. if you cant get the pin out just chop the plug wiuth a sharp knife.
