I’ve been considering doing a manual swap on my 97 recently and have a few questions for those that have done it

I’d really like to get an entire donor vehicle but finding a junk 5 speed within a reasonable distance seems almost impossible, so is there any source where I can buy the engine wiring harness and ecu? And do they have to be from a 97 or would a 96 or 98 harness work? How about from a Tacoma? I understand the ecu plugs are different between the years but would that still be a problem if I am using the matching wiring harness?

Another thing I wanted to know, could I use a Tacoma as a donor vehicle, they seem to be more plentiful, but would things like the pedals and drive shafts work?

And finally will this be drivable with my Aussie locker or should I consider going to a selectable, I really like the lunchbox locker and the street manners are excellent but I’ve heard it can be harder keep from chirping tires with the manual

Thanks for any advice, I’m just trying to determine if I should keep looking for an appropriate donor vehicle or just piece together components from junk yards as they become available
