90 VW 2 wire IAC ?

[Fisk1]

Iam putting a MSII Ver 3.0 together and Iam little confused on FIDLE setting.
So if Iam wiring into a two wire IAC valve. Do I use the TIP 120-122 transistor? I guess Iam confused where I put the Transistor on the board?
And what wire is it on the DB37?(is it one of the Stepper Outputs?)
In Help would be Awesome!
Thanks!!!!

ermz , u r mixing up fidle with pwm idle ??????

for fidle (used on old cis injected engines) u dont need to replace any transistors. u need relay to switch it on/off (actually , when engine warms up and ur fidle module is bolted to engine , it will close anyway)

for pwm idle (on newer european engines , bosch two wire pwm idle valve)
u need to use TIP transistor and pwm idle valve will connect to same pin as fidle usually connects (directly , without realy)

hope this helps.
