So, ive had a nice project going for the last 7 months. I have a question about upgrading my coil pack though. I was only able to find 1 thread on swapping from the old 3 wire coil pack to the newer 4 wire diamonds that came on newer subies.
As far as i know i believe i have to bypass my cars original igniter that sits directly above the transmission. The diamomds have their own igniter in the pack if im not mistaken? I wanted to know if anyone else has done this besides the rob 4 to 2 conversion for the 20g ecus. Should be pretty stright forward, i just need confirmation if i need to bypass my original igniter or not.
Car is 91 legacy wagon LS. 22e/25d hybrid. Vf28 and small fmic. Running speed density off of tunerstudio. Trying to start it here soon.

Re: 3 wire coil pack to 4 wire diamond pack.
Pictures are, of the harness i created to use to the 4 wire coil pack, and the motor all complete waiting to have its first breath of boost.![Image](//uploads.tapatalk-cdn.com/20200719/c03332f01fc4d106823156dfc643587d.jpg)

I haven't really researched this, but yes I believe the newer coil packs have a built in igniter so you would need to figure out how to wire things accordingly.
