Power Mode - Pin A4
hello all, I was doing the power mode mod to my 92 SVX. I made a pin, stuck it in the back of A4 of TCU. However, no Power Mode light comes on when I put the car in gear. The Power Mode light does work at ignition.
I am getting voltage on the wire from that A4 pin... it sparks a bit when I hook to ground. Is this normal?
Also, when A4 is hooked to ground, my check engine light comes on and car runs really rough. I think my TCU has a short in it? What do you think?
Thanks for the help.
