Convert your dx or a junkyard dx harness which will most likely be more widely avaliable then a si harness. Or if you want you can buy a brand new crx si engine harness for around 200.00 from the dealer if there even still able to be bought. I bought a brand new one a long time ago for around 200.00 and it was the last one (this is going by what the parts seller told me at gettel acura) Last one in the country. Find someone that knows there shit on wiring on tamparacing. Like neal sutton (cxcivic) I heard hes good with wiring.
