I just sent Hoppy a pic. I see my 64 has a 5 wire harness. I wish I had more times to look at the ECU to see if it's a 4 wire. Ill get over there tomorrow and check it out. Let's see, you can use a 4 pin on a 5 pin system or the other way around? Damn, I just read that yesterday.
I understand, our brains need a reset at times, i have to read something twice with in 20 minutes then when I get to the firewall I have to have it right in front of me, do you have a double ballist resister Mike?
