Ty, you need to specify which fuel system

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"

you dont realy need a diagram... seriously.

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.

if it was me... id be looking for that engine, to computer harness.... i may be able to find you one, within the next few days.

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.

Archamitis, Unfortunatly I am in wales UK so shipping my be pricey. But otherwise great idea as the engine is wired right up to the plugs but the previous owner just sliced the wires just after the plugs.

 

Skip, I have an '86 system if you have any more info I have a friend who is a whiz at electronics who can wire it all up for me. Thanks all Tom.
