So, I have a 1981 BJ42 with possible electrical issues.. I know my headlights are 24 volt, not sure what else is. I need wiring diagrams for this DIESEL Land Cruiser, and any info on which wiring harnesses I might be able to use from other make/models, if any.. Also, I'd love to simplify this if I can, turn it into a 12V system where glow plugs and possibly a heater go thru the second battery.. Basically, convert it to a single battery system where a second battery is used in winter.. 10 minutes with a heater and it starts like it's a hot summer day at -5* F.. Also, I really hate chasing shorts, so if anyone can recommend someone good at it in Erie County NY, I'd love the referral..

 

I think that you can contact an electrician, he will surely offer you the right solution. A good electrician could be a solution to the problem. When I was doing the wiring in my house the electrician from https://bates-electric.com/locations/charlotte-nc/ knew everything. He was the one giving me advices on what, and how it should be done. I loved having a pro doing this for me because I knew that when he finishes the job everything will be working great. Before doing stuff like this, it's worth doing the research and finding the best possible solution to the problem.
