Anyone out there installed a dual battery system in a 1991 80? Seems like all the guides cater to the 93-97s. If anyone has suggestions for placement and battery trays that would be much appreciated.

Thanks for the reply - I saw that it was the case but because the configuration of the engine bay is different seems like that won’t work. The washer fluid bottle is in a totally different location. Looks almost like either up back near the horn or on the other side of the air intake would be the best place for a second tray

Should work no problem, you only have to remove the fan setup on the right side. The "injector cooler" apparatus or whatever the heck it is (believe "engine cooler" is correct term) is basically a hair dryer pointed in the intake manifold's general direction. Might have to "relocate" the EGR as well, can't remember though.

This is great intel. Thanks so much. I had not previously seen a pic of a 91 done this way. Time to get to work!
Why do you want a second battery? That ground terminal on the battery you have looks like it's about to break.

It’s fully broken - I just got this home and it has a lot of issues that need addressing. I have new terminal on order.
Second battery is for the fridge and the winch!

Managed to get this all sorted out this weekend. Using a battery tray from the FZJ80 was a great suggestion - we did the “hair dryer” delete and there was plenty of room to fit it in. Happy to field more questions in the future if people have questions about the kit we used etc.
Was the hair dryer delete all that you needed to do? How does this effect the vehicle?

Just seeing this now, but I did some research when recently re-wiring my terminals on my dual battery '94. At least with the IBS dual battery controller on mine, they specifically note to wire the winch to the primary battery with all other "extras" pulling from the secondary...fridge, secondary lighting, extra outlets, etc. Hope this helps and that your project is coming along ok!
How’s the setup working are you stilling running it aside from the fzj tray what kit did you use?

Works great! I will see if I still have the full parts list somewhere.
