Hello to all and thank you in advanced.
I started redoing my wiring in my 89 180 with a sr20 red top about a month ago. But I've ran into the issue that my the motor cranks over but I have no spark, Ive checked the brown and big gray plug that go from the engine harness to the body harness but can seem to find the way to make the coils have spark. I've looked at all the possible diagrama the only thing that they have in common is something about a eccs. Wtf does that do and have you'll ever ducked with a painless wiring?
