I have a 90 crx i think its a hf. i put a 93 ls in it but havent wired it. Some dude told me that he could do it with the stock hf engine harness. Is this true? he also said he could use the 93 ls ecu, but i checked and it wouldnt plug up. Man im confused, does any body have any tips.

 

if its a HF the engine harness will plug right up with no problems but the ECU would have to be a 90-91 Ls because in 92 they went OBD1 and the ECU changed along with some of the electronics. So you need a 90-91 LS ECU

 

thanks for the info. another question. will my 93 ditrbutor work on an 90-91 ecu?

 

no sorry, it has to be a 90-91. You have a OBD1 Diz. you can get a OBD0-OBD1 Jumper harness for a bout 150.00 from blownhatch. May save you some $$$$ in the long run instead of buying a new ECU and Diz just get the jumper harness and a 4 wire 02 sensor and plug and play

 

what do u mean a jumper harness from a blown hatch? u mean like cut the ecu plugs off another car? As for the o2 sensor i think my down pipe has that four wire one. thanks ur alot of help.

 

blown hatch is a user, he sells jumper harness to convert your car from OBD0 to OBD1 https://honda-tech.com/zerothread?id=465128. yeah seeing you have everything OBD1 already I would go with the harness idea
