I was wondering from those in the know about doing a OBD 1 B18C swap in a CX. Does it make more sense to buy the 4 wire O2 jumper harness from hasport (i think thats who makes it) and use my CX harness. I was told this can be done but havent done all of my research yet. Or to just go ahead and buy a USDM harness and not worry about it. thanks for the help.

 

Use the harness that comes with the B18C. Life would be easier for you if you were to buy a B18C harness.

But it is possible to convert the 1-wire to 4-wire, although you will need to wire up other things as well.

 

My swap hasn't made it here yet should be here later on this week, but it comes with the JDM harness which Ive heard is pretty useless. I'm trying to get everything in order so i'm not waiting around on stuff and have the warranty run out on it. Thanks for the input,

also anyone who may have a USDM OBD I harness, or know a good place to get one I would appreciate it. Also looking for a decent header, and air intake if someone wants to get rid of some stuff.
