When you guys were using the coil connectors for the "Godzilla" coils, what kind of pliers did you use?

These are the first thing that I found when I did a search.

Mean crimpers for the pins? I didn't see anything at the temu link. This is what I bought that helped. I also already had a non-racheting open barrel crimper.

I guess I haven't updated this for a bit. The engine runs great, yea there is some drivability things that still need to be tuned and wiring clean up I need to do. But on course and under full throttle this engine is a ripper. It does feel stronger and responds better than with distributor setup. That could also be due to getting a better tune with Decipha than what was on their previously.

My mustang is not a street car. It is mainly used on an autocross course, but there is a lot of on and off throttle. Last year I got the car running in May. Took it to Autocross Week in June where it autocrossed all week along with driving in between each venue for a total of 500 miles. Overall last year with this ECU/ignition setup the car competed is 33 events and racked up 220+ runs.

The best part, for my local club's year end championship I won first in class and first overall, while my girlfriend one first in her class as well.

Yea there is a lot of suspension work done, but without a powerful and reliable engine that would not have been possible. So big thanks to Decipha for pioneering this swap and the tuning. Definitely way more affordable than going aftermarket ecu and gets mostly the same functionality.

Great to hear about the performance improvement. Also great to hear about first in your class in your local club and first overall.
I see the Temu link doesn't work because they sold out of the cheap pliers. Mine from Temu look a lot like what you have.

ADDEDAfter looking at your pictures, I hope my cheap pliers have the correct jaw.

I just re-read your thread to see how to properly hook up the Godzilla coils. I do see where you side that you had to swap the wiring on the coils. Would you, dleach1407 or someone have a pic of the coils showing how to wire it? Thanks.
