I'll check the pin for you tomorrow, think it's a19 offhand though. I'm using a manual ecu by the way.
OBD1 has two pins for the lockup, one full and one partial. Neglect the partial one and get the full (a19 I think) and I just wired it to 12v. It kicks on like normal due to pressure just being constantly wired. I have a switch though to keep it off during cold starts and such, pretty simple.
how bout a closer picture of your ecu
there's no way its a manual
unless you added the high-side switch
i can see the high-side switch in the picture already
which is what controls the 12v/ground output on A19
thats an auto ecu bub
Yes, I added the 5151s, but for whatever reason it still will not engage the torque converter, so I said screw it, a friend is sending me a free auto p06 any day now so I'm not worried. A stock auto would come with two 5151s anyway.
