I ran a search and didn't come up source for early year toyota ECU terminal pins. I'm mid process in re wiring my knock sensor but the only part i have not been able to source are Pins to re-pin the 2 wires on my yellow plug 18 pin connector. Would anyone know what the specifications on these pins would be or where to source them. I contacted Tweaked performance to see if their pins could be used but i was told the ones listed on their page are not for early yellow connectors like my 88 has.
