I have a 91 Civic Lx 5-Speed and i was wondering if a Ef Si wiring plug up to my Lx Fusebox? The Engine bay wiring and underdash wiring.

and i thought it would make it easyer. so i dont have to cut wires for the mpfi swap and for an engine swap. whats the difference, between si fuse box and dx or lx fuse box?.

i did this. i took the whole harness from my crx si and put it in my civic dx. it was simple i did all the wirering and swaped the motor in a day. and i didnt have a shop i did it in my back yard. so if u can get a complete harness do it.

 

I know that but i was seeing if the underdash harness from an Si 88-91 would fit on a 91 LX AKA DX fuse box... Because if it does im just going to by a Si Engine bay harness and Underdash harness and plug it to the LX AKA DX fuse box

 

my si harness pluged into my dx fuse box

 

I was wondering the same thing I have a 91 Crx Si shell with the complete motor transmission and wiring. I wanted to see how hard it was to just swap all the wiring completly to install this motor into my 91 dx civ hb are you saying I can just follow the harness into the car and unplug it at the fuse box to keep from cuting splicing and repining connectors ?

 

it was very simple for my swap, i actualy used my si fuse box and plugged all the tail lights and **** into it. it was simple just remove all the wirering from the si and compare it to the wirering in the dx and u will figure it out.

 

Shweet thanks Yellow Rex for the info

 

eee thats tiiight so all i need is a underdash wiring since i have the si engine harness
