I've got an 86 n/a. the motor was replaced with an 87' engine and an 87' wiring harness





I am trying to reground the BOOST sensor (passenger shock tower) I have these color wires......



Thick solid black wire, with a thin white stripe and yellow dots



Thin solid black wire, with brown dots



Solid brown wire, thin white stripe, with blue dots



Solid brown wire, thin red stripe, with blue dots.





I've heard so many different colors in the past couple of weeks and I DO NOT want to fry my ECU.. please tell me which wire would be the correct wire to ground... thank you very much
