I'm putting a b18b1 from a 94 teggy into my 97 Civic Hx. I've researched through the forums for a while but I still have some questions. If i get a p75 ecu and a rywire jumper, can i just hook up the obd1 ecu to the existing wiring in my car. I'm sure people but obd1 motors in obd2 cars all the time. What's involved? There's probably a thread on this that I missed, but if someone could give me some info i'd appreciate it, cause I'm on a strict timeline for doing this swap and I gotta get all the stuff I need pretty soon. Thanks
