I have been kicking around the idea of a 4.3 and reading this I think I'm gonna go for it in my 88 4Runner. Looking on painless I only see obd2 harnesses p/n 60215 for the extended length. Being a auto tech I really appreciate obd2 for diag and simply seeing what's going on. Any one go obd2?

 

Did you use the Toyota gear driven case or did you go with something else?
I want to keep my transfer case Toyota, but am not comfortable taking the entire tranny apart to change the output shaft are there other more simple options?
