...I got a wrecked Integra, the motor is still good too. I am planning on putting the LS motor into my 91 CRX SI...Do I need the LS wiring harness for this swap???

 

nope.. you can use your si wiring harness.. it's a plug and play with it.. just change the injectors..

 

ummm no need to change more than injecters unless its a 90-91 than just plug ur harness on it and thats it the 92-93 has a completely different set of plugs that will not plug into ur harness without modification.

 

The wiring is all plug in play, but remember that you need a mount kit for the engine to bolt into a CRX.

 

that is not true i have a whole 93 teg for a parts car and i know that it will not plug into the obd0 plugs not happening unless its a 90-91

 

Oh crap, I automatically assumed is was a 90-91. Sorry, my fault.

 

damn, I just sold my LS wiring harness...I really didnt think i'd be needing them...how much would it cost to get me some new ones???
