KA24E to KA24DE problem

[DS562]

this is my first swap and im a little confused. i read the write up on nico but it doesnt address this specific situation.

im taking the dual cam out of an automatic 96 S14 and putting it into my 1990 5spd S13, which had a single cam.

now i know i need to take the ECU from the s14, but can i use the automatic wiring harness? or can i just find the harness from a 93 DC and use it?

also, the write up on nico stated that i need the tach from a dual cam in order for it to work, is that true? cause i never heard of that.


thanks for any help.
