Regarding installation, is it possible to splice into the ECU wiring instead of removing the console/seat/wherever else there is to splice into the wiring and splicing in there? I have a ECU patch harness, so it is better if I splice in there. Which connection should I splice into in the following diagram:

I am assuming it is pin 75, but I just want to confirm with those that have done it this way.

I am hoping it is as simple as splicing into one wire, but according to the the people at o2simulator.com I need to put in a resistor for the secondary o2 heater sensor. Anyone have input on this? Thanks.

 

Anyone have any input on this? I'm sure many of you have changed out the cat for a hiflow cat or cat delete.
