YJ vs. CJ firewall electrical connector

I just bought a late 80's YJ tub to swap onto my CJ frame, grill and fenders. I've had the body off my cj before so I'm not intimidated by that aspect. It's all the stuff attached to the firewall that looks like a can o' worms. In particular, can I just re-use my CJ wiring and fusebox? Does this YJ already have the heavier duty heater fan? Looks like I can bolt my CJ heater box right on in place. A local jeep restorer here does something like the Blazer heater core upgrade, but he uses YJ fan motor instead. When did YJ's start using a more powerful fan?

Re: YJ vs. CJ firewall electrical connector

Not sure about the YJ heater motor, I upgraded from CJ to Blazer motor.
All the electrical stuff from your CJ should work just fine. I was able to reuse my fuse box and everything just fine when I put my YJ tub on. I did have some extra holes in the YJ tub where more stuff obviously went through the firewall on the YJ, so for now they are "plugged" with duct tape (great stuff).
I had to drill new holes to mount my CJ battery tray. It was in a slightly different position then the YJ tray. If you have to deal with this on your new tub, then you will have to remove the heater box to mount the battery tray(for access behind the firewall), then remount the heater box.

Hope that info was somewhat usefull.
