All,
I have a 78 FJ45 LPB that I plan on throwing a 3B + H55 into shortly. I am down to the frame and ready to put in new engine mounts prior to cleaning up the frame and painting/galvanizing/powdercoating it (dunno exactly which to do yet).
For the swap I have a donor 12V BJ60 (rust bucket with a good engine & tranny) and a 24V 81 BJ42 donor for all the other componenets (rad mount, front disc axle etc.)
My question is this. I want to run the truck at 12V similar to the 60. I won't be needing 24V as this truck is going to be a pavement mostly, gentle offroading, summer only "Princess". This truck will not be seeing winter at all so sub zero starting will not be an issue. I figure for accessories trailer lights etc. 12V will be the easiest way to go for me.
This is my first conversion so I am at a bit of a loss as to what I need to do for the wiring harness for the truck. Do I simply use the wiring harness off the 81 BJ42 and run it at 12V? I don't see why there would be a problem with this, am I wrong here? Any gotchas that I might need to worry about? What happens with the headlights if I do this? I understand that the 24V trucks only run 12V headlights, will I have to make some modifications to the wiring harness? I have thought about this for a long time, and I am really excited about moving on this project.
Any and all help and advice would be appreciated.
Thanks
Adam
