1G S90 Throttle Body TPS Help

[JT90LASER]

From what I've read I'll need to modify my current stock TPS to fit the S90 70mm TB, or " you may have to switch to a 2g TPS which incorporates the 4th wire which is the throttle close switch (IPS) on a 1g"

Need to find the best solution.

your best bet is to look at a factory service manual and go from there.
it should say what wires go where etc. and should show where the throttle closed switch is located if any.

Ecmlink can simulate your throttle close switch.

Don't mean to hi-jack the thread but I didn't want to start another one.
Is it possible to install or weld a throttle body switch to the s90 tb? These were design for the 2g and evo3 not exactly for the 1g dsm which uses a throttle switch. Some people have run the s90 without the switch and are doing ok. But this isn't to say that everyone will have the same luck. Others aren't running ECMlink to do the simulation.
