Did I Mess Up My Ecu?!!

[drz]

I was trying to reset my oil service light (by the way, I put in Mobil 10w30, is this good for Arkansas? First time using snthetic - I think I may change the oil after 2000 or 3000 miles this first time; call it "break in") and mistankenly connected pin 7 to the positive battery terminal instead of using pin 19 or any other good chasis ground. The worst part is that -- since it wasn't working -- I kept trying over and over. Now I read about 11.5 V on pin 7 with a voltmeter with the ignition on and nothing else connected to it. I have read a ton of other posts and other forums online and found one (and only one) place online that says pin 7 normally has +5 V. Is this right? Have I killed (at least part of) my ECU?

how is the car running?

The car runs fine, which I know means I could not have killed the ECU, but I am still concerned about the SI pin and what I did to it. BTW, I used a direct connection (no diode or resistor). Thanks

You should be fine.. most of the wiring in these cars can hold more than they are used for... dont worry about it unless you are having problems.. and or something is absolutely wrong with your OBC.. and or tempo of the car.

Good Luck,
