1990 coil in a 1991

What modification are required if any to place a 1990 coil into a 1991?

First, do a search before posting questions as this has been answered a lot.

Secondly, don't do it. Go buy a 91 coil pack. They have a different power transistor and wiring harness. You'd have to hack your wiring harness and replace the power transistor. It'll be easier to just buy the right part.

Actually, I've been researching it since I did a 91 JDM in my 90 and was having tach problems. I found three or four threads on it. Most were revolving around the tach not working after a swap.

FWIW, my tach still doesn't work I think the reverse polarity may have @#$@ed it up. The two odometers and tach signals use different polarities to work.
