I know that people say that it is pointless to put the SafcII on the tC but I've had luck with it on my other cars so I figured I'd give it a try but I cant find a diagram
for the tC's ECU to match up. I've searched the forums for one but I guess I'm not looking in the right places. So if you guys could help me I'd greatly appreciate it!

hope this helps

 

thanks man but ive searched those already!

 

All you need is the ECU Pinout - it's on Dezod's website under Technotes. IIRC I believe the SAFC interrupts the MAF signal and taps into the tach wire.

Than of course you need power and ground, but this really shouldn't be too bad of an install (Well I am comparing to the fact that I hard wired my Ultimate, which is about 50-60 wires to connect lol)

That is exactly what I needed! Thank you!

 

Here is the ECU Pinout for 07-10 Scion tC

E8-3 / Ground
E8-20 / Throttle
E7-28 / Airflow
E5-1 / RPM
E4-1 / Power



__________________

 

red wire- power
green wire-rpm
gray wire- throttle signal
brown wire-ground
black wire- ground
yellow wire- airflow signal output
white wire- airflow signal input

*** airflow wire has to be cut in two****
*** ground wires have to be install 3 inches apart from each other********

 

I forgot to mention that the tC runs on HOTWIRE, sensor 24-24

Got it! Thanks Jimmy!

 

jimmy (soy de PR)

is this pinout the same for a 2010 XRS??

 

saludos!!!!!!

nope its not the same ecu pinout.... your ecu has two plugs, one super big and one small.
