dui tri power questions

"Their website" is full of crap.

If you originally have a 2 terminal ballast, do as I said earlier above post 9

If you have a 4 pin Mopar ballast, you can eliminate a couple of things and clean up the wiring. Carefully unwrap or cut open the factory harness in the vicinity of the ballast, and pull out the wires going to the ECU connector. Replace the 4 pin ballast with a 2 pin, connect what's left together, and run off to the new distributor.

What year is your car? You have a shop manual?
