I just finished putting in a 4.0L from a '98 XJ into my '90 YJ - also added a 700R4 transmission. Everything appears to be working fine except the charging system.
I had the alternator checked and 2 separate Auto parts places and both said it was fine. The old alternator had a plug that just plugged in but the new one ('98) has 2 studs and is supposed to have some kind of connector that is bolted onto the back. I just connected the wires to the studs since I don't have the connector thing. Is there something else I should be doing here?
