mass air flow monitor
your EA82T has.
Up to 1986 they had a vane style MAF
(also called "flapper door")
in 1987 they switched to a
hot wire MAF
the systems are different wiring wise
see recent post "EA82T"

do you have the harness from the motor, to the battery?
if so, you have all the info you need.
the wire goin to the plus side on the coil, is also the on off for the computer.
black/white. stick that to the ignition switch + or the original +wire from your stock vw coil.
the big red wires, through the whole harness. they are power for the injectors and the computer. give that power all the time, with a fisable link, or a breaker.
the fuel pump wires. you can see where the old fuel pump plugged into the harness, i think its black and blue wires. those go the pump. you can hotwire that, or let the computer controll it(this is wher i cant remember the colors)
whats your mpfi harness from, an xt im assuming/hoping.
i think all of these wires come off of two main plugs, that go over towards the fuse box.
basicaly it should start when you put power to the black/white wire on the +of the coil, the big red wire, then hotwire the fuel pump. refine it after it runs =]
if i can find where i got my diagrams from, i will post them, but i think they have been deleted.

it would make things worlds easier for you. i just use that part, and tape off the wires i dont use.
if you want, i can check if one is available... cheap =]

Scan of the plugs is on the way to you.
Arche's idea is worth looking into.
Neuro - email me I'll see if I can get you the scans for
your system. Please tell me the type of MAF you have
or the year of the system.
