help!! 20vt wiring
« on: 18 November 2008, 21:38 »
hey everyone.im having a bit of a nightmare with mk 3 gti 8v to 20vt (arz)wiring..basicly i have the 20vt engine loom and ecu,but i also have the the 2 plugs from the other side with about a foot of wire which has been chopped because the person i got it off couldnt be arsed to remove the rest of the loom from scuttle backover.i have the clocks and key but no ignition barrel or the rest of harness.its drive by wire but im using my 8v throttle,so im guessing the imobilized ecu will be no good or need unlocking?also will the ecu still work ok with DBW converted to cable?and finally..with the chopped wires i have can i get it running if i graft them into the old 8v loom using mk3/4 wiring diagrams?qpe option is not affordable right now i just want it running
i only have wiring left to do and im itching to go :-) all help will be great

many thanks

stock ecu makes for a better conversion anyway   a lot safer for your enigne. 

the loom looks scary right now  but there not that bad,  most of the wires are easy to work out even without diagram.  converting the dbw  is possible on some of them at least
all the VW's have gone bar 1.

Unless you have an ECU with the security burned out you'll need ECU, clocks, key and the inductive loop from around the key all from the same car.

It's all coded together.
Just because you're offended doesn't make you right.
