How to install and adjust a 1998-1999 4.0 distributor? (CJ-7 MPFI upgrade)

I know this is basic, but I haven't done this type of distributor before.

I'm moving from a hybrid EFI system that used the old CJ (Motorcraft) distributor to a new HESCO/MOPAR setup that uses the newer 98-99 type.

I'm familiar with installing the old type, setting the timing, etc. but the new one apparently only controls the injector timing. How should I install it, synch up with the #1 cylinder, etc.?

Most of the articles I've found talk about marking the position of the old one, etc. but obviously that is not possible here. I know it's probably a simple thing, I just need some instructions.

Yes you should line it up with cylinder #1 spark plug tower which is at the 5 oclock postion on the distribtutor then pull the indexing pin on the the timining plate. Benny at Hesco should be able to help you if you have problems.
