does anyone have the step by step on how to install a TII Facttoy ECU into 1st Gen,what wire i need to install with out the rat nets

 

look in the archives i got a thread in there on s4 wireing very simular as s5

 

best thing to do is get the driver side harness pigtail from an FC that plugs into the ECU. you'll need it for CAS and coil wiring.

pretty sure it will work from any FC as long as its S4 or S5(whichever ECU you have)

 

i have a Facttoy ECU from a 87 t2 and the motor is the same year

 

i look at your tread is this the plug that come out the driver side harness pigtail.and how do i wire up power to it

 

anyone

Here you go.
This is S4 specific,there are lots of other threads on the subjuect if you search.
Only about 10 wires are needed on the left side harness for a basic running swap.If you want a bareblock,no smog gear swap,youll have to strip down the huge right side harness and extract the injector,AFM,MAP and other wires......at that point,you might as well save the hassel and run a standalone.Itll make more power and use only a fraction as many wires.
