Hi I am new to this site and could really use some advice.

I have a 3vze v6 from a 1988 Toyota pickup which was bolted up to a 5 speed manual trans. I want to put this engine into my 1991 pickup which currently has an auto transmission.

I have heard and verified that the injectors from the 88 to the 91 have different electrical pulgs. Is it easiest to switch injectors and seals on the motor while still on the engine stand?

Also want to know if I am going to run into any complications because the motor came out of and standard truck and is going into my 91 which is auto?

Does anyone have additional advice for me?? Please help!
