how to swap a si motor into a 1990 hf crx

i have a 1990 crx hf with a DX motor, si intake and ecu already installed. I want to put my si motor in what do i have to do to the wiring harness?

hello anyone there?

yours is an obd0 if i'm not mistaken. are you putting in the d16z6? if you are you just need to get the obd0-obd1 harness conversion to a p28 ecu 90% sure. then just wire the vtec solunoid(sp?) straight to the ecu harness. i'm used to doin it in a obd1 car so its alil different then this but not much. just conect your stock harness plugs to the motor. there are a few thing more but this will give you an idea

search dpfi to mpfi.

u want to put in the si engine like the d16a6 (88-91 si? ) well eather way weather u r talkin about that or the 92-95 si/ex (d16z6) eather way go to www.rywire.com and go from there as far as your harness goes everything else u just hook up as if u were switchin engines i think~marcus
