Not a drop in and go job. Recommend reading the stickies around here...

Wired for sequential or wasted spark? OEM ECU or standalone computer?

I believe that it requires a stand-alone computer to adjust dwell settings. I'm not an expert on those coils and what they require otherwise.

You mention it is oem ecu which is not going to work well because the dwell requirements are very different. Also you dont mention if it is 1.6 or 1.8 etc. A NA6 requires rewiring so remove the igniter where NA8 coils have built in igniter. You really just need to read the stickies about these but the first step is you have to use a standalone if you dont want to be constantly burning coils
