Uprated Ignition Coils for 1NZFE - Toyota Yaris Forums

Parmas · 08-08-2010, 10:47 AM

I am recently installing a new engine management and I got a doubt about the coils connection terminals.

In the engine managment manual it says that the positive terminal must be common with all coils while the negative terminals must be connected with external ignitors then to ecu. The problem is that the common wire in the coils stock loom is color coded Black and White and I am suspecting that the wiring needs to be adjusted to match the my management.

Scioncrew.. since you have experience with these coils, do you know which of the terminals is negative or positive?
