if i get a si underdash harness will it plug right into my dx crx or will i have to mod .

are they the same plug????/

 

hrmmmm

the si has a sunroof, and that might plug into the under dash harness. the si also has a tach, and its wiring is part of the under-dash loom.

I cant see why the guts wouldnt be the same though, just a few extra wires strung thoughout the si harness....

dont quote me on that though... good question btw, I've never heard/seen this talked about.

 

also, the under dash harness for 88-89 are likely a bit different from the 90-91 harness as they repositioned the hazard light switch and possibly made a few changes in its routing to accomodate that
