1990 13b to 13bt harness issue
 

hi there im having some troubles and was wondering if someone could point me in the right direction. iv tryed looking threw the forums but cant find anything.

i have a 1990 rx7 13b n\a and i have a 13bt that is going into it. i am having some issues with the wireing harness and want to know if i am able to use the n\a harness on the 13bt and if so do i have to frankenstein the harness? thanks so much

They're is few threads about it but Rotarr on this forum can answer your question regarding the electrical of the swap

ok well second question. is there a write up/chart for the conversion between the 2 im finding some connections that are non exsitant between the 2 motors

Post your research & a bit more info on your setup , it's easier to see where you at & help you bro

ok well all research iv done on this there all saying lengthen some connections and wire in the knock sensor but dont say how to. and there are some othe connections that i have found on the t2 that are not on the n/a and i dont know what they are. from what i can tell both these motors are s5. a lot of the connections do look the same just a couple arent. ill take some pictures and post.
