The car is a 92 if that helps, also what I don't understand is where I
plug the wiring harness to on the back of the fuse panel. i know that
I shouldn't have to rewire the entire dash.

The Engine Control Module (large black box)
The Ignition Module (small palm size device) sits on top of the ECM.

So you are removing the Digifant Fuel Injection and replacing it with the
Passat's.

You need a Bentley for both the Golf and the Passat to read the wiring
diagrams and merge the systems!

Well then theres no wire for the ignition module, and that goes to the
coil, so any ideas?

Will do, but I cant till I get paid, i believe I get the idea, the
wires that connect to the ignit module connect through a different
sizeconnect then those wires go from the wiring harness where they
connect to the ignition module then the coil and such?

Will do when I get paid, till then I'd like to know if there's a
seperate wiring harness connector for the ignition module that then
goes to the coil?
